Brake pedal pulsing after changing rear brakes

In the past...there have been members that bought the power stops
and had problems with the front rotor/calipers pulsating....and had to return them

and there's been several.........all of em power stop

I personally bought bendix shoes for rear ....because they're $28

didnt feel right from the beginning .....6mos in the front shoe on each side was down to half thickness of the two rear on each size


I bit the bullet sprung for the real ones from Mcgeorge......never looked back
