Brake noise

Postby fcanary » Sun Jul 03, 2016 3:08 pm



I replaced my brake pads on my '86. Compressed the Pistons correctly, installed the pads correctly, reinstalled the calipers and torqued to 20 on top and about 15 on the bottom. Front rotors looked new rear was ok with some scoring. Flushed the lines and had good pressure. Took it down the street and did several "hard" stops to seat the pads as one "how to" said, with no issues and was quite happy. Did one more and now it seems I have a noise coming from the left front and rear. Almost like a high spot on the rotor. A squeaking or even a grinding sound. Do dragging right or left. No smoking like they are too tight. Is this normal until they really seat, or did I do something wrong and need to start over, by pulling the calipers decompressing the pistons and basically start all over again? Any thoughts?

Have a similar problem with my 81 1100. Front has a squeal that is very loud. Checked the pads and they are fine. Found that if I hard brake once in a while the squealing is reduced or stopped but comes back in a short period of time. So I am interested to see what kind of response you get.

You should never just slam on the brakes to get them to seat. Your just putting a glaze on the pads and rotors.
I would just stop mildly to start. One thing you can try, is file the leading edge. So that the pad isnt totally flat but curves up some. Some pads these days come factory with the leading edge with a tapper. That will help them not to squeal.

Didn't mean to imply that I was seating the pads by braking hard. This has been a squeal that I have had for a couple years. Very irritating!!!

But I will definitely radius the edges a little and see if that helps. Thanks

If you're not replacing the pads I would rough them up with some sand paper also. You can use sandpaper on the rotors, take some of the glaze off. Then wipe the rotors with brake clean to get the dust off. I also use rubbing alcohol to get the brake dust off. Sometimes the alcohol is a lot cheaper compared to the brake clean, and use it for more important things.

make sure all the anti rattle springs are there. And all the hardware is in good working order.

You have to watch those springs. mine came with the pads and there were two different sizes in the package, Mine uses the larger spring.

Make sure your rotors are not to thin, that can make noise resinate. You could use ceramic pads, they work well with less noise and dust. The semi-metallic pads are the noisy ones and hard on calipers too. I ve never used on bike pads, but on cars. Brake quite....or similar. Put on the back of the pads next to the pistons.
