Why do my brakes squweeeeel?

[Bambikiller240]

Silicone Brake grease and new anti-squeal shims kept mine from being noisey for the 20,000 miles I had the car before I completely rebuilt the brake system this past summer. I reused the shims and applied another coat of grease on the back of the new pads and ....................(sound of silence!)

Duct tape sounds like something Kyle would try!

Who you think taught him?? I have a hard time buying----BRAKE GREASE!!!!! As a comedian I heard once said.I don't need that!!!!

OK, went to NAPA today and they also sell this orange stuff that looks and smells like glue. Does it work? Does it get hard or does it harden to silicon-like felxibility? Is it goinging to be a mess to scrape of when I do them again? Anyone?

Hi Daniel:

I know what you mean. I'd always thought that you had to keep grease and oil away from brakes PERIOD, but I when crewed for my (now) ex-father-in-law on a Trans-Am series Corvette back in the mid 80's, they were applying it to the back of their Disc brake Pads routinely, and he clued me in on it's benefits. It is a very hi-Temp grease that does not melt and if applied THINLY, it will not migrate to places it should not be.

I'd be afraid that the Duct tape would catch fire or melt from the heat and booger up the rotor or pads since it's not designed to handle heat.

Steve:

What is the orange stuff called? The Silicone Brake grease that I buy is CLEAR and comes in a plastic (toothpaste-like) tube. Says right on it "Hi-Temp Silicone Brake Grease". What I purchase does not harden. It does not melt either. Just sits there. Removes easily with a rag and a bit of CRC Brakleen or paint thinner when needed.

Yes, I founbd the hi-temp brake grease...this stuff is over with the magic potions and is a little tube and is called Disk Brake Quiet.. There were two different brands and both looked identical.

You guys might find this odd, but I've never used anything except the shims on any of my Z's and have never had squealing brakes.

Even using Carbon/Kevlar pads on the race car they were quiet, and I've always used some type of metallic pads on street cars.. maybe I should shut up before I ruin my luck huh?:stupid:

Naw, just count your blessings!. On my first 240Z (a 73 back in the mid to late 70's) I didn't use anything but the shims either and never had a problem, though I knew people who did have Squeal problems. I wouldn't be surprised if the quality of manufacture and the pad friction material has a lot to do with it.

I MAY have seen that too. It sort of sounds familiar, but I have no experience with it.

I just had mine done and they squeeeel too but only after driving a few miles. When i had my 240z they squeeled too but after a 1,000 miles or so they settled in and stopped making noise! go figure. anyway, i'm not sweating the squeals until March!

Zvoiture -

When mine squealed like you discribed

I pulled the pads out with out removing

the caliper - I ground a small lead on the

leading edge of the pad so the leading

edge did not have a right angle to the rotor

face - squeal GONE - this allows the pad to

set in as that lead wears off - by that time

the squeal would be gone anyway. Oh- you

still need the squeal shims mentioned by

bambikiller and tomanyz's.

OK, just changed my brakes and got the squeals too!

Where do I get the Shims?

I used the hi temp grease and still got the same squeal.
