1987 gm high sierra 4 wheel drive truck, new front pads,new rotors, when i apply the brakes i get this high pitched squeal. anybody know how i can stop this irratating noise.
-
how new are the components?
-
rotors and pads are about 3 months old.
-
Did they just start squealing or have they been squealing since you changed them?
-
started squealing about 2 months after i installed the rotors and pads. by the way the pads are the very best i could get, and i was told by the salesman they would not squeal. one other change i made about a year ago,was i installed new leaf springs on the front i went from 2 leafs in the springs to 3 leaf in the springs. this raised the front of the truck about 1 inch or less. would this effect the combination vavle for the brakes?
-
The combination valve would really only effect the rear.
Brakes squeal due to pad vibration. Remove the caliper, clean and lube the slides so that they move freely. Put a little bit of moly grease on the back of the pads where they contact the caliper and piston.

that did the trick. thank you very much for the tip.
