Triumph TR6 - squealing front brakes

Basic question, can anyone advise what the cure is for squealing front brakes noise
Bob

Hi Bob from the UK
Yup 2 options. Ear plugs or a very loud car stereo

oops sorry meant to add more ...darn enter key after spell checking.

OK joking aside. I have exactly same problem. Rather embarrassing noise. Happens mostly when brakes are hot and at intersections with 500 people scrambling for cover figuring they are about to be hit with a car.

Charlie Ballard has suggested to me to bevel the leading edge of the pads.

I have tried both anti-squeal compound and the MOSS supplied anti-squeal shim plates. Both made no difference.

I wait to hear from others on this subject.

I assume the front brakes are not worn :)
Instead of the anti-squeal shim plates you can try copper-grease. Just put a little on the outside (!) of the brake pads.

I friend with a TR3A replaced his front caliper pads and they squealed. He took them out and tried everything. Nothing worked so he sandblasted them. The squealing was gone. When it came back later, he did it again. Give it a try.

Bob-I too had a frustrating problem with squeaky front brakes. My final soulution was the shims with the cut outs from TRF. I also used some of the "blue goo" between the shims&pads. Squeal be gone.

I also had a very embarassing squeal from my front brakes. The TRF anti-squeal shims took care of the problem and 3000 miles later I'm still squeal-free.

I recently changed to "Green Stuff" Kevlar pads. They have a sort of anti-squeal backing pad already, so I didn't re-use the factory steel shims. Only 500 miles so far, but all's smooth and quiet...

And I thought I was the only one. I get tired of cute girls in Mustangs looking at me as if I were a sea slug. If the brakes did not squeal I am sure the looks would be admiration and awe. I have new disks and green stuff pads with about 2000 miles on them. The back of the pad has a neat circle worn in the material spead on the back. Local car store said try silicone. Worked for about a week and half. I will try the shims.
Dick Porter

Thanks for the warning, Dick. Guess I'd better hang on to those shims when the material on the back wears through in 1500 miles! I put in new rotors as well.
Maybe the squeal is the built-in Pedestrian Warning Device.

Thanks for your comments fellows, I thought it was just me!!
One of my work colleagues had a Dolomite and said sqealing brakes used to be the norm, he suggested bevelling pads and shims.
Copper grease apparently is used alot in the US according to a web site, it acts as a barrier between the two metals.
Bob

I found bevelling the pads made no difference so I tried this and it worked on 2 TR6's...no noise for a couple of years...

Buy HEAT resistant brake lubricant..I use kleen-flo EZE-SLIDE.

Clean the metal sides of the pads and the channels where they sit in the calipers..the most important part is to spread some eze-slide on the sides of the pad (just the metal..not the actual pad ) where it contacts the caliper and slides back and forth. You don't need lots.

I also cleaned and put some on the back of the caliper but if you already have that silicone stuff it should be okay

Bob/Charlie:

Would a lubricant or copper grease find its way to the pads and the rotor or would it stay in place? Interesting squeak problem which I have not yet had, however, last nite I installed hi-perf pads in the 6 but it rained last nite and all day today and I have not yet driven it so I don't know what to expect re squeaking. Question??? My anti squeal shims on both sides are pretty much triangular in shape. I thought they should be rectangular but the TR6 manual does not show the shims in detail. Are they triangular or rectangular meaning mine have worn about half out and simply fell out the bottom?

Cheers,
Bob

Hi Bob,
My shims are rectangular...I gues any shape will work as long as it's larger than the piston area. I've never had a problem with the lubricant getting on the pad...you only need a small amount just to coat the metal part.
