Brake noise...

[Groo]

Was riding without my XM on a day or so ago, and noticed that my front brakes seem to be making a sharp squealing sound if I'm slowing down to come to a stoplight... Not the normal brake pad on rotor sound... much louder and sharper. The bike stops fine... and the Spiegler lines seem to be working like champs...

I pulled the pads out, and they're all fine... the rotors look ok too. Could it be that one of the pads has a strange wear pattern that needs to get worn down over time to eliminate the noise?

Curious if anyone else has run into this, and/or if you did anything to make it stop.

Put grease on it....that'll stop the squealing. :lol:

My buddy tried that on his Montgomery Wards 3 wheeler (we were about 10), watching him hit that fence was priceless! :haha:

A comment like that requires pics.

I wish I had pics... But like I said it was over 30 years ago.

Oh, he figured grease wouldn't be a good idea.... so he used WD 40 instead! :lol:

I am going to bring wd-40 to all the bike meets I go to. We'll have a brake spraying contest.

:lol:

Though you mentioned everything looked ok, did you also thoroughly clean both calipers' pistons?

Without seeing the bike, maybe you have glazed rotors/pads from overheating?

Don't know if the FJR pads have audible wear indicators or not?

Recommend removing them again, clean everything including the pistons and maybe even sand the pads and rotors. It just depends on what you find in there.

HEY.....let's not accuse anyone of thinking in here.....I am 12 beers deep and the rangers beat the red sox tonight....which I saw personally.

When you did the Spiegler swapout, did you also get the Carbone Loraine brake pads? Did you transfer the stainless steel brake pad shims to the new brake pads. Reports have come in that these shims control some brake squeal, and if you didn't know they were on the brake pads, you may not have transfered them to the new. Just sometime to look for.

Thanks for the non-grease/WD-40 suggestions....

I also have the Carbone-Lorraine pads, actually had them longer than the ABM rotors or the Spiegler lines because they were the easiest to install. I did reinstall, and have the shims from the original pads... I didn't clean the pistons, i.e. disassemble the entire brake calipers. If it keeps on making the same sound, I will though. The pad surface didn't seem glazed when I pulled them off last night.
