Technical High pitch sound coming from rear and can't Id

This truck has a new aftermarket rear brake kit and plenty of pad. Once on the road and warmed up a high pitched squeal like when your pads are warn down. These pads are near new. This squeak happens while moving and goes away when brakes are hit. It's driving me nuts. Definitely the rear as I put it on jacks and placed my truck in drive it started to squeak like the video. not a constant sound and exactly like the video.

 

and you don't have dust shields rubbing, like the guy in the video did?

Might just have to bite the bullet, and put drum brakes back on it.

 

No dust shields. That would have been too easy

 

Maybe you could make a video of yours, so we can see/hear it? up on jack stands would be good.

Disc brakes do like to squeak. Also, does it have a drum park brake inside?

 

Maybe the rear u-joint, when you apply the brakes it may change the pinion angle enough to stop the squeel like a

 

I'll try and get a video but in the mean time I'll hit dome spots with brake cleaner and see if the noise goes away so I can narrow down where it's coming from maybe..

 

Make sure the pads are tight in the caliper.

 

Pads tight in the caliper


Do the pads have the “ low pad warning tab”?
Little bit of metal that touches the rotor when the pad gets low?
They squeak just like your describing
