Ok. I've put anti squeal coupound on the back of the pads. I've replaced the rear brake shoes and all springs and hardware and fixed and adjusted the e-brake so I know the sound is not coming from the rear brakes. I've put shims on the back of the brake pads. Could the squealing POSSIBLY be related to the one piece "spring" that keeps the pad-holding pins in the caliper? Might the brake pads be playing this spring like a violin string? This spring does touch the top of the pads, in fact that is where it is compressed against to gain force to hold the pins in the caliper. Can I take out the spring, and find another way to hold the pins in? Or is that spring supposed to suppress rattling or something? Here is a top-view of the spring. The pins go across the top and bottom sections, while the pads are below, and touching, the left and right sections providing the force to hold the pins in the caliper. Thanks for any help.
