Squealling brakes......cause of???
What is the cause of squealling brakes? Pads...rotors....both?
I took all the pads off and used a drill mounted wire wheel to remove the glazing off the pads. This got them quiet for about 5 miles...and now its back. I get a loud squeal when I first apply the brakes and then if I keep them lightly on rolling to a stop. If I come down firm, no squeal....but drag the brakes and oh.....my ears....
I have no idea what brand the pads are...came with the car. I believe the rotors are original as the rears are still riveted on...no idea about the fronts. The calipers are all new from VBP, couple of years ago.
Should I just get a new set of rotors and pads and be done with this or is there something else I need to do?
Brake pad brand that are quiet?
Anyone running with drilled/slotted rotors?
Thanks for all comments.

Lanny,
I've been doing brakes on Corvettes for 27 years. I've fixed this same problem many times for very low $$$. Go to your nearest auto parts store and buy a tube of "Disc Brake Quiet". It's a thick liquid solution usually blue or red in color and only costs about $6.00. Remove the pads and put a liberal coating of this all over the metal side of the pad where it contacts the caliper and re-install.
The squeal you're hearing is caused by a high speed vibration of the pad when braking. The Disc Brake Quiet bonding material is designed to prevent this vibration. Don't let a brake shop convince you to resurface your rotors unnecessarily if they are not out of round as this will just use up the life of your expensive rotors.
Many people with the same problem have been convinced to pay for resurfacing all four rotors and after they are done the technician will add the Disc Brake Quiet anyway. The customer is convinced the rotor resurfacing did the job.
Good luck,
Greg

Could the squealing be caused by dirt on the rotor also?

I have seen this "Disc Brake Quiet" stuff under many different names...have never tried it....but am going to give it a try now.
Funny though....drove the 81 several times yesterday....and one trip...got no squeal at all....other times...it will shatter glass within 50 feet..
Going to the parts store now.
Thanks,
LannyL81

Not usually. Even if your brakes had a lightly rusted surface if they'd been sitting for a while a couple of applications while driving would clean them off. Dirt, water, dust, etc. is the same way. If those types of things caused a squeal disc brakes would be impossible to keep quiet because they are always going through something that will get on the rotors momentarily. Their ability to self-clean is another terrific point of disc brakes.

Greg
