I don't know how everyone's brakes feel when they're stopping, but when I brake it seems like I have to push almost all the way down to get the Av to stop. It's almost like the Av is to heavy for the brakes. I have new brake pads, so that's not the problem-it just seems like the truck doesn't want to stop. I found this on CAFCNA-do you think something like this would help???

Linky thing

When running bigger wheels other than factory,really puts a lot of stress on these tiny discs. Its been said that if you upgrade to bigger wheels you need to upgrade the brake system as well. Sure upgrading is the way to go but $1,500-$2,500 for the BAER or whatever other setup,is way out of my budget

I think our discs are 12". Upgrading to 14",im sure it will cure most if not all headaches when stopping.

bluedevil · « **Reply #2 on:** November 06, 2007, 06:07:45 PM »

One more thing.....i think but not sure. If you upgrade to 14" discs,your factory 17" wheels wont fit. I think is for 20" wheels and larger.

You have homework to do

MoAv · « **Reply #3 on:** November 06, 2007, 06:17:01 PM »

Yikes-is that how much that set up costs? Wow...guess that's not gonna happen anytime soon...

You're right Blue-I'd better start doing some homework. I just don't like the feeling I get when I'm stopping. I'm afraid of what would happen if I had to stop in a hurry.

Yep. The AV is lil' over 6k pounds of steel. Is somewhat hard to stop it with big wheels at high speeds.

Easy over 2k for BAER discs and pads. Now thats a good brand but theres others out there to choose from at somewhat cheaper.

It is probably old news now. I just did the GMT900 brake upgrade on mine. The '07 and newer models received upgraded front brakes. The rotors are one inch larger in diameter and an easy bolt on upgrade.

I went with local "performance parts" from NAPA. The application that I used was a 2007 Tahoe.
Eclipse reman calipers with brackets, Reactive One slotted bidirectional rotors, Adaptive One ceramic pads. The total came to just under $420

Some comparison shots:

Brackets and to rotors in the background

At first I thought that the caliper pistons were smaller. In the first shot it looks that way, but the second shows the larger piston of the new caliper. Very deceiving.

A comparison of the pads shows only a small increase in contact area. Most of the swap benefit must come from the mechanical advantage. The rotors and pads will be the rest of the improvement.
Reports are that 17" wheels are the smallest to fit.

You can see that any bigger than this is not an option.
I have had only limited testing with these rotors in the fleet. They do bed in pretty easily and evenly. It is a little too soon to say just how much of an improvement they will be , but with the "rose colored glasses" still on, the improvement is noticeable. Less effort to bring this thing down. It feels much better.

Nice set up... True if you do do bigger tires and rims you should upgrade the brakes.. I went with the full SSBC in my last truck.. My new one has the short stop system About $450.. Slotted and Drilled Rotors and Hawk Pads. Been happy with this set up on 20's...And I can still put my factory 18's on for the winter...

oHIobellboy · « **Reply #7 on:** April 17, 2011, 10:42:59 AM »

Something for me to look into also with the bigger wheels and tires. I'm gonna pull an Enkei though. A guy that sells EBC brakes is offering free brakes if I do a write up and video for his website.

The other thing that 02 owners should consider is going to the hydroboost setup. I will probably do it one of these days, when I need new brakes.

Are you talking about just rotors & pads or the whole shooting match - calipers, brackets, rotors, & pads? Either way, it sounds like a great deal to me.

I need to set up a meeting with the guy. He's a customer of the advertising company Twiggy works for. Find out exactly what all he wants to donate to the cause. Those pads alone are $125 a set. I know those are in the deal. If the rotors aren't then I'd like them for cost. The calipers are going to have to come from somewhere else I'm sure.

AvalancheAviator · « **Reply #13 on:** April 19, 2011, 01:22:08 PM »

I'm really liking that 07 Tahoe upgrade. But, I've got a couple of questions. First, would that change in rotor diameter cause the antilock system to behave differently? Second, is there a similar upgrade for the rear brakes as well? Personally, I'd like to upgrade the whole truck if possible.

No/ The ABS system senses differences in speed. It will not be affected.

Quote

...is there a similar upgrade for the rear brakes as well?

Not that I have found. We already have the larger rear disc brakes. Pads could be improved and maybe some matching slotted rotors.
Much less braking is done by the rear as all the weight transfers forward. Any increases to the rear performance would be minimal improvements when you consider the percentage of work they do.

I'll likely replace the calipers , pads , and rotors on the rear eventually. If I can match the front rotors , I will do that. Right now it is not a priority as there is life left in them.

AvalancheAviator · « **Reply #15 on:** April 19, 2011, 05:09:56 PM »

Ok, understood. I might still go ahead and do the whole thing, just to get new parts all the way around. The system does have 140k on it. Thanks for the input.

Henry, how are those upgraded front brakes working out? I know it's only been a month. Have you noticed an improvement already?

HenryJ · « **Reply #18 on:** May 26, 2011, 05:24:04 PM »

It just feels right. Much improved from before. I don't notice the additional effort that was needed before the swap. A panic stop before was a little unnerving. I really had to push hard to slow it down fast. Now there is no extra effort needed to bring 6700# to a stop.

Two thumbs up here.

HenryJ · « **Reply #20 on:** May 27, 2011, 09:26:38 AM »

Even if all you are doing is a normal brake service it just makes sense to replace the parts with the late model ones and go to the bigger brakes up front. I just did a quick cost comparison and found the cost of the "upgrade" parts is less than $40 more than the stock replacement parts.
The complete upgrade can be done on the cheap for under $230.
For all those with 17" wheels, it is kind of a "no brainer" when choosing the front brake replacement parts.

AvalancheAviator · « **Reply #21 on:** August 05, 2011, 09:58:43 PM »

A bit of an update...

I went and pulled the trigger on the Napa brake parts. Including the slotted rotors and ceramic pads for the rear. Unfortunately, the pricing was more expensive and it's gone up again. Front brackets, calipers, rotors, pads, rear pads and rotors cost me just under $900. Pretty steep, but if I see a massive improvement, it's worth the money. Tomorrow's the big day. I'll report back after she's all done.

AvalancheAviator · « **Reply #23 on:** August 06, 2011, 03:52:58 AM »

Yeah, it is the gmt900 mod. I just went one step further and bought matching pads and rotors for the rear.

Can't wait to see the pictures!! I recently bought a set of front and rear DBA rotors and SS brake lines which were a PIA to replace. Noticed a difference after replacing the brake lines - braking was stiffer/firmer not so much of a difference after installing the drilled and slotted DBA rotors - UNTIL I had an emergency stop on the highway... WOW this thing brakes now. Well worth the money. Best part though is "No more Brake Fade"!!!! I used to have this terrible problem on my 02 where after an emergency stop or braking over a long trip the brakes would become less and less effective. Actually after a hard stop or two they would become useless at high speeds.. pretty scary. Spent about 175 per DBA rotor = 350 total for the DBAs used a new set of Stock Delco Pads. Spent 110 bucks? on the Russell stainless steel brake lines. 460 buck upgrade - saved me like a week later from a Horrific accident

Russell Stainless Steel Brake Line Thread can be found here - http://www.chevyavalancheclub.com/index.php?topic=13147.0

Some pictures of the DBA rotors and info on the install afterwards - http://www.chevyavalancheclub.com/index.php?topic=13223.0

Well worth the money, just wondering whether I shoulda just went with larger disc brakes in the front and did the whole caliper/bracket and everything else upgrade. Also, like I've said in the other thread(s) DBA paints their rotors... unfortunately paint doesnt last... Doesnt affect performance but the orangey rust doesnt look great ether.. I highly recommend anyone interested in new rotors get some that are Zinc Plated not "painted". The DBA "Kangaroo Paw" vents Do work. Its not hype these Brake discs dissipate heat Like a B*****!!!!!!

P.S. The brake upgrade I did was prompted by the 20inch rims and 33" tires I recently added to the Avy.

I'll try to post some more pictures of the DBAs behind the wheels soon.

AvalancheAviator · « **Reply #25 on:** August 06, 2011, 07:04:18 AM »

Glad you're satisfied MM! And still in one piece!!

I was thinking about going with high performance rotors and pads, but a friend of mine argued against it. He had his wheels off his 02 Tahoe and had his S.O., significant other, hit the brake pedal. He noticed that our front calipers flex outward under hard braking conditions. Of course that means massive uneven braking. 2 or 3 hard hard stops? Warped rotors and wasted money. I don't know if this is a design issue or something that happens as the truck ages. All I know is, I decided then to replace the calipers. Not only for the bigger rotor, but to hopefully solve that flexing problem...

As for the flex lines, I'm going to have them made. That same friend offered another compelling arguement against ss braided. He said that if, heaven forbid, you bottom out and crush the line, you instantly have no brakes. They don't crush and bounce back, they break. I think the pressure capacity from the factory is about 300 to 400 psi. If I can get just double capacity of factory, I'll be happy. He said that we could get 3000 psi, but I think that might be overkill. Plus, that has got to be a very stiff hose and might not flex very well...

Anyway, I've got to pick up the rotors and rear pads today. I just found out that it's going to rain, so it might be next weekend before I attack this and post pics...

Happy Trails!!

MonstaMonsta · « **Reply #26 on:** August 06, 2011, 08:32:15 AM »

Thanks AA! Mee too

Flex outward? Yeah I want to replace the front calipers just because they look terrible. I've Stomped these Brakes going from 100 Miles/hr. to almost a stand still more than once already and they're still flat. I may be lucky with my choice and these DBA rotors may be made really well. I don't think they're warped, I may be wrong... I dont sense any odd motion when I brake. These rotors are exceptionally thick, and the vane design might be saving them from being warped (They have this interesting "Kangaroo Paw" Vane Setup) I just don't know - anyone's input here would be awesome. I do know they run cooler than the OEMs rotors.

I'm super curious about the "flex outward" motion you said your friend noticed when the brakes were pressed. Do you think our OEM front rotors are made in a way that accepts this outward flex or are they being punished due to being old or maybe design flaw by GM? When I was picking up parts the other day from the dealer he said that the front rotors usually go on these trucks/ they warp and need replacing after a period of time.

I wish I had found this thread when I was buying the front rotors. I like the way you're thinking

... I woulda bought the rotors for the 07 up "the larger diameter ones" and went ahead and purchased the bracket/caliper setup and been done with the brakes... ofcourse when the mod bug bites theres never a "finished" only a "currently satisfied"

hmmm..

As for the SS Lines. I see you're friends point on the bottoming out and, god forbid, the worst happens. I feared more - that the rubber hosing would eventually degrade and possibly burst. I feel safer with newer SS brake lines vs. the OEM rubbers "especially since they provide stiffer braking". I think I would understand your friend better if he were to provide some sort of secondary rubber tubing around the Stainless Steel Braided line in order to provide a secondary fail safe tube? I don't know. Nor am I sure. I do remember the various manufacturers (Goodridge/Stoptech/Russell) that I was to choose from rated their SSB lines anywhere from 2000 Psi to 3000 Psi.
I did'nt go with Goodridge or Stoptech because I wasn't sold on their quality and didn't like the reports that the aluminum banjo bolts that came with ether set of hoses breaks when tightened due to the aluminum construction.
^ Again this is not from my own experience anyone who knows better feel free to correct me. The Russell SSBL don't even come with new banjo bolts. I just thought the Russells "looked better" and was reassured by a fellow member "waz" who installed them on his 04, and his other trucks. He highly recommends them, and so far so do I! Heres the Russell Brake Line Thread (Haha, I see you've found it already Thanks for the answer to the hub question AA!)

-> http://www.chevyavalancheclub.com/index.php?topic=13147.0

I don't know what the Russell brake lines are rated at. Heres the website with the russell lines, its probably on there somewhere, http://www.russellperformance.com/mc/brake_hoses/hoses_domestic.shtml

AvalancheAviator · « **Reply #27 on:** August 07, 2011, 06:25:56 AM »

You make a very good arguement for ss braided, MM!!

While I was picking up the rest of the parts, I got new front flex lines from napa. I'm going to give those a shot for now. My dad has a 2010 Sierra and his brakes are much much firmer than mine. I have to believe that the newer flex lines have something to do with that fact...

As for the caliper flexing....
I have to believe it's due to our trucks' age. Maybe I've got the rose colored glasses on, but I don't think GM would put a flexing caliper on their 6500lb, full size trucks and send them to the dealership. Yes, they would put brakes on that are too small.... I mean, think about it. If it's supposed to flex, it would get worse and worse as the vehicle ages...

Ok, I've had my coffee. Time to attack this job! I know, I know. GRAB THE CAMERA!!

AvalancheAviator · « **Reply #28 on:** August 08, 2011, 08:45:28 AM »

I just did the GMT900 brake upgrade as well but no pics, I was in a time crunch to get the job done. I went with the same front rotors and pads as Mike (OBB) and I purchased a set of drilled and slotted for the rear from the same ebay guy. I also went with the NAPA Eclipse (07 Tahoe) front calipers and brackets, I broke off the bleeders on my rear calipers so I went with the Eclipse for the rear and while I was at it I swapped out the e-brake shoes. There is a difference but I would probably notice more if I had changed out the factory rubber lines.

Did you do the bedding in process per the included instructions? 5 moderate to aggressive stops from 40mph down to 5mph without letting the brakes cool down and do not come to a complete stop. Then do 5 moderate stops from 25mph down to 5mph and let the rotors cool after each brake application. You should expect to smell some resin as the brakes get hot.

I've been reading this thread about how weak the brakes are on AV's, but I noticed on my 02' if I need to stop fast and I put it to the floor, the wheels start to lock up. To my understanding, if the wheels are able to lock up that is a good thing.

The key to really good brakes is how much braking power can they apply without locking up. Larger diameter rotors and good pads come into play in making this happen.

In my opinion the upgrade was worth it but I think it could be better if I would have spent the extra money and went with a set of braided brake lines and removed the original ones. Total spent was $765.11 - the core charge of $118.25 = $646.86. This price includes front and rear drilled and slotted rotors with ceramic pads (GMT900 front), stock rear, new calipers with brackets front and rear (GMT900 front), stock rear and e-brake lining.

I've done quite a bit of research on it and yes, a factory Av setup should work fine. You need the brake pedal in addition to the hydroboost and you have to tap into the power steering pump lines unless you also get the hydroboost power steering pump. You have to tweak the firewall slightly to get the new setup to fit exactly. From my research, the bolt pattern on the hydroboost master cylinder is a little different than the one on the 02s.

I don't know if it will help but, I can add a my $0.02.

There are two vehicles in my yard that have the GM hydro-boost system. My '04 AV and my fathers '02 1500HD Silverado. I don't know if they have the same bolt patterns on the firewall or not. It might be worth me taking a look. If the '02 is different then the '04, you might just avoid the firewall tweaking.

Where should I look for this slight difference?

The tweak on the firewall is to drill another hole a little lower and to the left or the right, I did read a little in regards to this. I think there were two different units, one with the assist and one without? I already have a brand new power steering pump in the basement that I need to put in so I would just tee the line in.

We can always install larger brakes, however, their comes the question of custom bracketry for the calipers, and you would also have to install a different proportioning valve. I come from the BMW world, where I had 12" rotors all the way around and if you slam the brakes the seat belt rams into your chest. The AV compared to my BMW doesn't have any brakes.

Hence why folks in this thread have been installing larger diameter rotors from later model GM trucks - the bracketry is solved for them by GM.

As far as a proportioning valve, dialing in what is needed there has largely been eliminated by the anti-lock brake system. Prior to anti-lock brakes, pickup trucks braked horribly because the proportioning valve setup was really a compromise between what was needed for an unloaded bed and one loaded to the truck's fully-rated load capacity.

when doing the gmt900 brake upgrade do the factory brake hoses fit the bigger calipers?

Yep! They sure do! Just make sure you get new banjo bolts. They're not included with the new calipers.

Edit: Since you'll be that deep into the job, why not go with new flex lines? They weren't that expensive when I did mine. Plus, you won't have to worry about ripping everything apart twice, if an old line pops...

I'd go with the 07. Actually, have the parts guy grab both and compare. If I recall, they're the same. However, it's better to inspect and be sure....
