Brake squeal solution....

I read on another forum where someone cut two diagonal slits in the brake pad material down to the back plate so that accumulated brake dust had a place to drain thus reducing brake squeal. Anyone done this?
 
Brake noise is from the back of the pads. Vibrations move the pad against the piston and the bracket. Noise reduction should start on that side with shims or the CRC disc brake quiet #05016. If your brake pads are not offered with shims many parts stores can order them separately. The material can be cut with shop scissors if an exact match to your pad shape cannot be found.
 
You can also try chamfering the leading edge of the brake pads 1/4" or so. Just enough so the leading edge (the edge that the rotor passes first as it spins when going forward) doesn't immediately contact the rotor. Use a file or disc sander to knock off 1/4x1/4. Then (sparingly) use the CRC blue disc brake quiet on the back of the pads.
 
If you cut the slits you want one section to be a little longer than the other. This forces each section to be resonant at a different frequency and reduces the energy at a single frequency.
 
I use Kevlar pads and have no problems with squeal on the MGB. I had a problem like that on my truck and did the same to solve the problem. It worked! PJ
