I hooked up my disc brake on my Champion Legend recently and it squeals when I apply it. That sometimes means glazed pads but it had only 300 miles on it from a previous owner when I hooked it up. He had it hooked up from the start and used it about 300 miles. Anyone got any ideas on how to quiet it down?
Hi Bob,
Grab a can of Brake Clean and some coarse sand paper. Pull the pads and scuff them and then clean them up with the Brake Clean.
Later,
David
Thanks Dave. I didn't think pads could glaze that fast but I'm probably wrong.I'm still trying to get up to Coos Bay to go riding with you and the other local guys. I'm going to visit a buddy of mine in about two weeks at a gold camp past Happy Camp and near I-5. I made that trip last year and had a great time.
Break squeazing starts when the brakes were used too soft for a long time /or patches are uneven worn /or there is a warp in the disk.
Any way make the clean up first and check for wear and warp. I have now a floating front disk different from the former bikes and it never squeezed except when one patch was worn down to the steel plate.(But it will make noise on gravel.) If you changed patches recently then you have to mold the patch to the disc by driveing and pulling the frontbrake at the same time.
Brakes want to be used and will glaze if not used strong enough.
Best regards

9 times of 10 brake squeal is vibration between pads and the housing. Apply a thin coat of silicone to the back of the pads..
Had the same problem with the brakes on my Spalding car from the word go. Recently put a floating brake rotor on the car so while I was at it put silicone on the pads. NO more squeal what so ever.

Brake noise is also cause by the weather.I know when it is hot and humid
my brakes squeal.You can sand the friction surface to remove the glaze and put on some
"brake silent" to the friction material but brakes do make noise
and it is something you have to live with.
You can try different pads/shoes from another maker but at a cost,
faster wear,more money,harder on disc/drum, or more noise,longer stopping
distance,etc.
I have Brembo brakes on my sidecar and they squealed, took them out and sanded them, they were good for about 200 miles, I think it's the pad material, next time I get ticked off enough to pull them I'm gonna put silicone on the piston side.
Pep Boys (and most similar auto parts houses) sell a product/products called, I beleive,"disc brake sqeal" (not positive of the name). It is a heavy paint like material brushed on the back of the pads, sold specifically to eliminate disc brake squeal.
I used this a couple months ago on the Wing, very easy fix, So far has lasted about 6,000 miles. I have used this in the past when I have had the problem.
So far, for me it has been an easy and cheap fix, much easier and long lasting than sanding the pads, etc.
If sanding the pads it is best to use a flat surface like a piece of glass for a backer.
Have had sucess with just putting a piece of masking tape on the back of the pads in a pinch. Probably not recomended though.

I don't really see why not. I've seen factory squeal shims on all types of vehicles that were made of cardboard, heavy paper, phenolic and other similar materials. While I'm sure the adhesive loses any of its properties pretty quickly the paper of the masking tape will continue to absorb the vibrations for a long time.
I'm partial to the spray on squeal stop (paint like substance) as I had good results with it when I was doing car brakes for a living. Time spent chasing squeals on warranty claims was time I didn't get paid for. A good rotor surface is just as important. I found that using a grinder with 80 grit sanding disc to put a "swirl" finish on the rotor helped to eliminate squeals. If the rotor is toast nothing you do to the pads will help.

"Silicone".

Copper lube is good for back of pads/shoes
Copper lube?? what is copper lube, did you mean copper base anti-seize
