Looking for ideas as I recently replaced the rotors and pads all around (actually upgraded the front calipers, rotors and pads to Defender 110 hardware).

Rear passenger wheel seems to chirp / squeak while driving at different speeds and not all the time.

The noise goes away when I apply the brake pedal... so either something is dragging or there’s a wear pad piece hitting the rotor?

Looking for opinions, thank you

 

Sounds like either a stuck caliper or a warped rotor.

 

I am going to take it out and double check. Calipers could be sticky as the previous rotors were rusty and the pads were ground down to nothing (and no, that wasn’t my doing... never lend vehicles to family members)... lots of crap to clean and maybe I didn’t do a good enough job cleaning them up.

Will report back once I have solved it.

 

when my wife (ex) had our Discovery 1, it did the same thing, she took it to the Rover dealer, under warranty, they replaced all the ABS sensors. I wondered why not just clean them.

 

next on the list lol as they are toast from being the originals

 

you want to know what the problem is? I'll tell you what the problem is. One of the pads has slipped from being squarely in the caliper and has tilted so that the metal of the pad will come into contact with the hub, causing anywhere from a squeak to a squeal. If you take off your wheel to adjust it and then drive it to the airport to pick up your kid, it can even start to jam in there and grind. Driving with your left foot pressing the pedal slightly gets you out of Oakland.

First round I took off my wheel and thought, wow, this will be an easy fix. So I took out the pads, cleaned everything and put them back in squarely. But one of them kind of shifted again so I re-adjusted it. Over and over. It just wouldn't sit square. Thought I had it but then the airport run. I fixed it by replacing the still-good pads with Brembo P44001 (rears) and got a positive lock in the caliper. Maybe I was doing something wrong, and maybe the last guy did too, but this solved it. Some of the pads have a step at the bottom but the Brembos are squared and just fit right.

If I'm right, you'll see a witness mark on the hub like below.
