My 1980 Honda station wagon's front left brake squeals. I have pulled the wheel, and everything looks fine. When driving, there is no perceptible drag or pulling to one side. It is simply a nuscience (sp?). Does anybody have a suggestion on how to get rid of the noise? Murray at Intel @ t4test

The disc brake on my bike squealed when new, too. It went away by itself. One thing I've heard is that some pads have some slop in their caliper so they vibrate when you drive, and when they vibrate into contact with the disc, they squeal. Heavy grease on the BACKSIDE of the pads to damp out this vibration will fix this. Au

I had the same problem with my 280ZX recently. A local mechanic
referred to it as "chattering brake pads". The remedy for this
syndrome was the one used by Mercedez Benz; the end of the pads
are beveled at a 45 degree angle (degree of angle can be disputed).
Example:
old - __________ new - ________

This did eliminate my squeling brakes; now I sneak by the state
troopers with NO problems. I hope this will help you.lrd@druri.UUCP (DuBroffLR) (04/06/84)
This has been the subject of much discussion in this group in the past. The pads on disk brakes will sometimes vibrate at high frequencies, causing a squeal. Your local auto parts store should have a product called "Disk Brake Quiet" (an indicative name), or other similarly named products. These products are aerosol foams or thick liquids that are applied to the back side of the brake pad (NOT the side that contacts the disk rotor and creates the braking action). The goop that has been applied dries -- or, rather sets, to a gel whose purpose is to damp the vibrations that are causing the squeal. I haven't used these products, but have heard from people who have; some report the problem totally cured and others say no effect. In any event, no harm is done, the (attempted) cure is not expensive, and doesn't take very much time.

Possibly an easy fix is to replace the factory brake pads with "metalic" pads. This worked like a charm on my car. It will also eliminate any "dusting" problem. -- --- John Bossert Boeing Computer Services Seattle, WA uw-beaver!ssc-vax!bossert

Regarding metallic brake pads... Be warned, however, that if you use metallic pads, one typical result is that the disks themselves wear out MUCH faster. And the disks cost a lost more to replace. Roger Webster (...ucbvax!trwrb!felix!roger)

Metallic pads have another problem, they don't work very well when cold. Any one with an automatic transmission will have great difficulty in keeping the car from creeping until the pads and/or shoes warmed up. Once warmed up, these pads have superior braking ability to the standard pads. A fair tradeoff if you cand stand it. P Kelliher AT&T-ISL S Plainfield, NJ
