What causes brake squeal, and what's the best solution?
I did the front brakes a while back and I noticed two things. One rotor has two colors on it as if one area isn't making the same contact. The other is squealing.
I used to use Disk Brake Quiet, but it didn't come with any and they want you to buy a large tube of it. I only need a small amount.
So here's the what I'm concerned about: Several shops said to use the caliper grease to rid the noise. As I understand it, the caliper grease is just to lube the parts that slide when you brake, I never thought that would matter in making noise. On our fronts, we just have that screw in peg that the pad float on at the very top of the pads. I don't see how that would make a difference.
The Permatex disk brake quiet also seems like it just absorbs the vibration, it's just a gel that sits on the outside.
So what causes it and what's the best way to get rid of it?
