C2-Brake Squeal

[john lokay]

What do I have to do to get rid of this? My brakes start to squeal after I have driven the car, once I get things up to operating temperature. Do I changed all the pads (and if so what type pads do you recommend) or should I take off the existing pads and apply anti-squeal pad paste or do I check the surface of the rotors? Also, I am aware that the corvette brake system can be a strange animal to work with, and as such, can a trust my local mechanic in town to work on the brakes or should I seek out someone who is more familiar with C2's? Thanks

Re: C2-Brake Squeal

John, I had similar problems on my car. At the suggestion of a friend, I beveled the leading edges of the pads. I put a 45 degree bevel on the edge (roughly measured) using my grinder. It did solve all of my brake squeel issues. It also solved the brake squeel issues on my 79 Mercedes too. I am a convert on this issue. Be careful of the dust from the pad and use a face shield.

Re: C2-Brake Squeal

I have the same issue with my 66 so I am looking forward to the responses you get. I had been told it would go away with use, but over 5000 miles later, I still get a squeek upon light braking after I drive for a few miles. The squeek stops when the pressure increases on the pedal. I have a 68 that does not do this, and I thought the brakes were the same, but maybe not. I don't know what kind of pads are in there, but I hope I'll learn something here.

Also, in the latest Restorer (I think) there was a reprint of an old GM service bulletin that talked about cutting away a portion of the pad to eliminate squeeks. I assumed all new pads would have that fix, but maybe not.

John,

I have not found the C2 brakes to be anything unusual. Anyone that is familiar with disc brake systems should not have a problem attempting a fix. I would pull the pads and do what Gary has suggested and clean/lube all metal to metal contact surfaces with the anti-squeal paste. My experience is if that doesn't do the trick them replacing the pads and surfacing (or replacing) the rotors is your next option.
