I discovered frozen front caliper pins that could not unfreeze. I had to go out of town so had service shop repair fix and put on new pads. I couple of days after getting the car back, the front brakes squealed like crazy, so took off calipers to discover lots of orange rubber goop on back of shim plates and one shim plate hang out the back side of caliper (not pretty).

I cleaned everything up and used a spray on back of pads and back side of shim plates. Quiet for a couple of days, now back to annoying squeal during slow stop. Have never had it this bad of a squeal. Calipers move freely on pins.

Suggestions anyone? Should I trash the pads and try new ones?

I would ditch the pads, and buy Volvo ones...it's all I use. I've tried aftermarket in the past, though they may have gotten better in recent years (I wouldn't know), and had a problem with them badly scoring the rotor, and the little brass knobbies (technical term) weren't as good at keeping the brake pads where they belonged...I'd get uneven wear, and a rattle of the pad in the caliper.

Thanks Chris

That orange goop is supposed to stop brake squeal. Never known it to work yet. All it seems to do is glue the pads to the rubber brake piston dust covers, making it difficult to remove the pads without tearing up the rubber. Ditch the pads, buy some decent ones (ATE or somesuch), smear the backs of the new pads with a high temperature grease (bearing grease is fine). Bed in the new pads using a few firm but not overly forceful applications of the brakes leaving a few minutes between each application.

Thanks Steve
