Left rear Brake

[apb2148]

2007 GMC Yukon 4x4. When I am at a complete stop and start again, it seems like the left rear caliber is dragging. So we removed the clips and slides. Cleaned them and lubed them. It went away for a little while, but then came back. So I said screw it, changed the caliber with new hardware kit as well. It seemed to be fine, but it started again this morning. What do yall think?

I have made it a habit of pulling the caliper slide pins annually. I clean them and use the Permex Green Caliper slide pin grease

Since then I have never had this problem.

This problem is more appearant in trucks that live in the salt belt or get dipped in the water for boats and such.

We did all that and it was still having the issue. We turned the rotors and it has stopped.

I noticed this too. Never had this happen to me before moving to a snow/salt use area. It sure is rough on everything under the hood and body.

I had the rotor turned and that seemed to help, but it is doing it again. They did say the rotor had to be turned a good bit, due to it being a little warped. Could that be the problem???

Maybe another item to check would be the brake hardware.

I just figured out a pesky grinding noise on mine that was driving me nuts. Turned out that there was rust on the caliper bracket in the slot where the pad retainers sit. They weren't able to seat in the slot fully and creating drag on the pads.

Last weekend I pulled the caliper pins and re-grease them but that actually made the noise worse. This morning I pulled the calipers again and noticed that the pads were stuck, I actually had to tap them out with the butt of a hammer. I ended up taking a file to the grooves where the retainer clips sit, removing all the rust, and a wire brush to the pad clips themselves. They now sit fully in the slots on the caliper bracket, moving freely.

No more squeal after a day of driving in stop and go Saturday traffic.
