When I backup, my car makes a loud and annoying screeching noise. I'm guessing the rear calipers are siezed(the front is all good). But when I go forward, it just makes the noise of worn brakes.

Suggestions? Thanks fellas.

 

It's most likely the brakes making the noise. The calipers could be seized or it could also be the pads have no life left and it's metal on metal

 

Thanks. I'm getting a new break system today.

 

Or it could be pads warn unevenly and the opposite direction of rotation hits the brakes in an unusual way...plus the pads are probably have high % of metal.

 

It might be that too. But I need to swap out the calipers, roters and brakes anyways the guy said.
