Brake Upgrade

[RST Dana]

Just installed the Brembo GMC kit on my Denali. Very easy except for getting copper washer off of brake line bolt. Just breaking them in, so I haven’t tried any hard stops. Shop around, you can find this kit for just over 2k. Tried finding a Denali with this option back in May when I bought my 18 but none were available. Option was around 2800 so it was more economical to add them myself. I still have old rotors and calipers as well.

Photos?

Not a bad price for those considering this kit:

For $1800 might as well get Wilwoods so you can get the matching rears later when yours cash supply rebuilds.

GM Performance/Brembo kit just installed by dealer. Massively better stopping power.

Only gripe is that the Adaptive Cruise isn’t as smooth when slowing down.

Cool. How much? They only offer on the front right?

Yes, only the front. Given the front/rear weight distribution of the Suburban the rears don’t do all that much.

I think they were about $3000 after installation. I also did the exhaust and front air deflector at the same time and it was about $5000 all together.

Weight distribution on subs is 51/49. But I get it. Just wish they’d have a full kit so it all matched.

The rears don't do that much on all cars. Fronts handle from like 65-75% ! Thats why you go through 2 or even 3 sets of front pads per one set of rears.

Weight distribution has less to do with how much the braking effort is divided front-to-rear than weight transfer does. Ask any drag racer about braking's opposite; acceleration, and he'll agree. Suspension geometry also plays a role. But SUVs, with their relatively high center of gravity and (usually) softly sprung suspension tend to transfer quite a bit more than a car would. I've not done the math specifically for a GM SUV. But on average for a sedan, the braking effort is 80/20 front vs. rear. It wouldn't surprise me if an SUV was biased even more. The incremental cost of the rear system, when compared to the incremental improvement in braking, is typically quite high. It doesn't surprise me that GM doesn't offer it, for that reason.
