Answer
Hi Earl... could be a couple differant things... check the rear end for fluid... also check rear brakes see if the pads are wore down to metal...check to see if maybe backing plate is rubbing on the rotor or if maybe stone caught in betwen pads and rotor. remove wheels and do overall check... hope this helps
