What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Rocket Man]

I wish I could score the '21 PPV brakes.

I ordered the standard '21 Tahoe front calipers. They're a fixed 4 piston caliper, they got a ****** shit ton more clamping power by design.

I still need to get pads and rotors....but those are easy to get. The calipers have been on a national back order and are still hard to get now.

The ‘21’s bolt right onto the NNBS? Need brackets I assume.

Nope.

The rotors will go from 13" to 13.6" so it should be a solid upgrade for the money.

How much more pad area?

I don't have this measurements, but I can get the pistons sizes off the new caliper. I bought one awhile back for test fitting.

I'll report back in a bit with that

Nope bolt right in with a single washer. They're a fixed caliper, so no bracket.

The caliper bolts to a bracket that’s attached to the knuckle in the front or backing plate in the rear. So these bolt right to the NNBS brackets? I know when I upgraded my NBS fronts to NNBS calipers and the larger rotors I needed to buy the corresponding brackets. Some calipers come with them included, some don’t. When I look up the part numbers you ordered I don’t see them included.

There is no bracket, its a fixed caliper that bolts directly to the spindle/knuckle.

So it must have the same dimensions as the NNBS..! Wow, that’s pretty sweet..

Yes, very similar.

These calipers run on a 13.5 or 13.6 rotor. So definitely an upgrade and no longer have to deal with sticking/seized caliper slide pins FTW

Sweet. What are these pins though when you look at the calipers at Summit? https://www.summitracing.com/parts/...l8HTjibEtXLF8ZEeZx_RlbA8cgrO7c6BoCNL8QAvD_BwE

Dropped the wheels off with new tires and sensors at a local shop to be mounted and balanced. Should be done tomorrow morning. Will be nice to have the 24's on again. It's been over a year I think
