Hey guys, here's the situation. I've got a 1973 Riviera. When I'm driving, I get a constant "cheep" sound that happens approximately once per tire revolution. As I speed up, it speeds up. I've had the drums turned, new brake pads, and I've replaced the U-joints. Sound is still there, and I'm not sure what else it could be. I'm not sure if it is brake specific or not, since I can hear it coming from both sides of the rear of the car while driving. Any help would be appreciated. Thanks.
Sometimes cheap brake shoes do that. It sounds like the material is too hard. You may also try backing down the adjuster about one turn but the noise may come back eventually. Have you tried sanding the shoes? :idea2:
If you put the rear of the car up on jackstands and run it in place, can you still hear it? You might be able to get really close to the noise that way and zoom right in on the brakes or wherever you hear it coming from. K
In reply to Devon, the last time I had the drum off, there were rub marks on the backing plate. What could this mean? Thanks a lot...
Rub marks between the brake shoes and the plate are normal, and are lubrication points for anti-squeal compound. My comment was aimed toward a potrential contact between the drum & backing plate, usually happens if a plate is bent from improper jacking or other influence. A warped drum could also cause this.
