2005 Suburban Brakes Issue?

[OR VietVet]

You are going to need a scanner like a Tech II to bleed system properly. If you didn't open the system it likely does not have air in the system but to collapse the pistons back may have caused a problem. Was this current problem happening before the front pads were replaced?

No, it only started a little after I replaced the brakes.

Dumb question (sorry): But did you get the correct thickness pads? If the pads are too thick, the brake fluid expanding would then cause them to stick -- right? Just a thought -- not a brake system expert.

Then you need to go back and recheck your work at the brake area. Check the sensors where they mount at the bearing hub and the wiring.

Good point @OR VietVet there was a TSB about corrosion under the speed sensor for that generation truck. Knowing about the salt helps support that. You could inspect where they mount after they are removed. Just be sure to put a rag in the hole before chipping any rust off.

Couple of suggestions. Make sure the caliper slides are lubed and the calipers are free to move sideways slightly. They should "float" back and forth (side to side).

Also, the flexible brake hoses can collapse inside and allow fluid to build pressure TO the caliper (as in the braking action) but not allow the calipers to retract. Solution for that is to change the flex hoses.

Hey I am a new guy on here. I have a similar issue. I’m in the rust prone area of the world. The wheel bearing seems tight to me. I have not had the brakes apart. I just bought it and the previous owner said wheel speed sensors. It’s possible. But from my experience the bolt doesn’t walk out. It more like snaps off and you end up replacing the bearing. I am hoping to hear what your fix is so I can start there. For me, if I push the traction control button, the Yukon will not have issues. If I leave it regular, after I leave the stop sign I will get the stability track message and it will make the buzzing sound. I’ll come on here if I fix it myself. But for now I’ll run it and let the problem present itself further.
