What did you do to your NBS GMT800 Tahoe/Yukon Today?

Bear77 - You're going to hang that on the wall of your garage, aren't you ?

The piston came out right after the rotor split, because the brake pad had nothing to press against. Because of the heat generated, you were really lucky that the leaking brake fluid didn’t catch fire. Thank God for dual reservoir master cylinders. Back in the “old days” you wouldn’t have stopped until pulled the emergency brake or hit something.

Not the angle, to me it looks smaller too. And another pic of the caliper. Seems like the caliper seized up and blew the piston...



What’s left of the piston...

That was not a rapid failure of the rotor. Here is what it looked like right before a fin pulled the piston out.

wow, just wow! I’m surprised it didn’t blowout both pads. Just when you think you’ve seen it all.

Just a thought, but I wonder if it got hot enough to compromise the wheel bearing

Will save it for when I do get one! Lol

Actually the backside brake pad or what was left of it, was still there. And no emergency brakes, those need to get done as well.

Didn’t even think about that...

Been getting the service 4WD message pretty consistently lately, and interestingly, the tcase seems to start out in Auto 4WD rather than 2WD where I leave it. It goes away quickly, usually right after turning off, and then pops up again a day or two later.

Finally caught it with the tech 2, and I have a C0327 code, so figure I need to replace the actuator motor, or possibly the TCCM.




Also getting the loss of comms message, and it won’t actually read data from the tcase as well. Here’s a video when I try to read the tcase data:

probably not those rear bearing are pretty hardy, I beat the crap out of my 00 for nearly 300k before the rear bearings started humming at me

Decided to clean up the grounds under the driver seat a little better. They weren’t terrible, but they’re a lot better now, and coated with dielectric grease.

my guess would be just the encoder motor I think they run about $160 for a REFURB
