Driver rear brake squeak

[Truestyle Scott]

So Ive narrowed this squeaking down to the driver side rear wheel. It sounds like a brakes squeal but only at a certain point on the rotor, so when you accelerate you hear the squeaking spot get faster and faster. Its pretty loud. Embarassing. Goes away while driving if you are on the brakes. I recreated it turning the wheel myself. Then took the wheel off and looked at the brakes. I changed the rotor and pad earlier this year. Also a year ago this corner of the truck was t-***** a lil, enough to ruin the wheels lip. It was repaired at the dealership. Anyway, the backing plate isnt rubbing, the brake pads are greased good to release, nothing looks like its wobbling that i can tell. Is this just a warped rotor? Or maybe bad wheel bearings? The accident kind of worrys me but it just started this 6 months ago. Anything else to check or try?

Could be a sticking brake caliper?

yeah, i should take out the pins and grease those up good too. Forgot to say, when i turn the rotor around there is a spot its harder to turn, hopefully its just brakes not anything axle related. Ill have to get the caliper and maybe rotor off to confirm the the axle turns without issue.

Yep. That's what I would do. Good luck keep us posted.

I've seen seized caliper pins caused squeaking since the caliper won't release smoothly. I'm thinking it might be the parking brake shoe though, if there's rust/dirt inside the brake rotor that might be your culprit.

rotor is pretty new so shouldnt be much buildup. Ill take it all apart this week and see how its looking. thanks all
