07+ Brake upgrade on a 00-06 NBS, is it worth it?

[1992rs]

I want to give my .2 cents on something I noticed.

I did the upgrade when I had my stock 17's. I've always noticed the petal was really light for maybe the first 1/8th of travel and when it finally felt firm, it braked too hard except for maybe panic stops or sprited driving. Maybe it was bleed poorly (I had a shop do it,) maybe not, I don't know.

After I installed my heavy chrome 20's the pedal was a lot firmer from the get go and stops much better now. Much of that obviously contributes to running a lower aspect tire, but the pedal feels more linear, Instead of dead space...then boom face to the windshield. I am depressing the pedal a little farther with the 20's but it still have plenty of bite and I've never had to put it to the floor even at quick 80+ mph stops.

It just so happens that I am doing all new front brakes next weekend. I ordered the replacement caliper/bracketss (for my 03 escalade) Saturday from my local O'Reilly. I will be ordering the 07-14 brakes instead since I have stumbled across this thread.

My truck has hydro boost and it's on 26" wheels. I am excited to be able to actually stop. The bleeders in the current calipers are seized and I went through a set of pads in about 20k miles. Which leads me to believe I have some sticking calipers.

I will update with a quick review once I have all the new parts installed.

I received my AC Delco / Amazon rebate today for the calipers even though I returned the GMT800's instead of the GMT900's. So either they didn't care or they didn't notice. It did take almost a month.

Good to know, I was wondering which way I was gonna go about where to buy the new calipers.

I'd be looking at relatively aggressive pads if I were you running 26" wheels. What pads did you order?

Looking forward to your review!

I'll run whatever is cheap. The truck stops alright for for having big wheels because it's hydroboost.

I've run a few different brands on my previous truck (titan on 24s) and didn't really feel much difference for the cost. $40 pads were fine and $80 pads were only marginally better.

Whats the wheels size you can run with 14"?...(asking cause my snows are still on 17"...would like to see that change to 20" once the tires wear out or get sold)

In my experience regarding brakes- the bigger the better. 14" with good rotors/pads should improve stoppage dramatically...

I'm gonna "guess" that the 17 inch wheels won't clear the one inch larger rotor?? 18 inch at the minimum ... I would think??

I believe 17's clear but not 16's. Didn't you do the upgrade while you had 17's @1992rs ?

To my knowledge this is true. 17" factory wheels will clear the 13"ers

 

[1992rs]

@Red Rocket & @TheAutumnWind are correct. I did the GMT-900 (NNBS) upgrade when I was on stock Denali 17's. There's no way you could fit a 14" rotor. I didn't take any measurements but I'm betting there was maybe half an inch of clearance between caliper and wheel. The only thing I miss about the 17's, it looked pretty aggressive.

Yep ... just saw this in here somewhere ... sorry lost track of where:

http://www.chevyavalanchefanclub.co...D=lpld7nq7oeor41e02sl2jp4ms5&topic=122524.125

But the 17 inch rims will clear the larger rotors the 16 inch rims will not.

So I did the upgrade. Rotors, pads, calipers and brackets all from a 2007 Tahoe. Everything bolted on as this thread suggests.

The brakes feel amazing. The truck stops hard and I no longer have a terrible shake in the wheel when I have to get on them hard. I was also fighting a random ABS issue that seems to be fixed now. I attribute that to the disgusting fluid.

In the photos below, the purple calipers are OEM. My reason for replacing was that the bleeders were seized. You can tell by the brake fluid in the Dr. Pepper bottle that it was in desperate need of a flush.

Last photo is a before and after. I had to install new tie rod ends so I took the opportunity to take some load off the torsions and put it back to stock.

The brakes look so much better on the vehicles with big wheels!

What rotors did you go with? I personally am a fan of blanks over slotted/drilled options so I like that you went that route and found it to be an improvement!

Great job @MikeLade ! Good to hear your brakes are working better.

I agree. The brakes behind the big wheels look much better.

The rotors and calipers are Brake Best brand from O'Reilly. I have a jobber account with them so the cost was my biggest concern.

Great job @MikeLade ! Good to hear your brakes are working better.

Thanks! Next on the list is braided hoses then lots of other goodies to possibly go to SEMA next year.

OK ... O7 upgrade are on my things to do list. I also have "Black Brake Fluid" and I get a "pulsing on the front brakes??

pulsing is likely warped rotors, which you would replace when doing the NNBS upgrade so that would fix that problem

Yeah kinda what I was thinking?? The rotors were turned and they look good ... but something is off??
