brake squeal.....(5 posts)

brake squeal.....buffalosorrow
Dec 19, 2002 5:49 PM
After a year of perfect bike performance with a rear SRP grumpy. It has developed massive brake squeal "MBS". I have the bike overhauled and the experienced mechanic could not fix it and suggested a v-brake with pull adapter (which I have on the front).

What it comes down to is the angle between post, canti and brake pad. When looking at the play between post and brake I can imagine the play and screaching noise, once this happens what do you do? Is the brake screwed? I have the matching brake on a different bike (no problems). What is wrong? I am terrible at a loss...

first try to finely clean the rim surface (fine steel wool) and brake pad. you can experiment with toe in on the brake. if you have some play or the pad is worn just replace the pad. are they the combo post pad like Spooky's or Froggleggs or are the Cartridge Pads? where is the play? is it in the brake or canti boss? we need more info

I have had no problem until now, I would have thought that the rims are 'broken in' aswell as the pads. As of the compete overhaul the bike received, new pads installed, It sill is squealing, just as before.
The play compared to my other cross bike, is in the junction between post and brake hole, it shifts a goon mm. An extra washer was tried to tighten this but according to the mech, the problem still exists.
I would liek to state that I think I has to deal with the shifiting, vibration of the brake and amplified through the pad, angle offset maximizes.
I have tried to 'toe in" the pad, to no avial. there is not much 'toe in ability" with the SRP's

ok I would have tought that the mech would have caught this one. After some drinks and thinking....the brakes were on backwards and in reverse.
everyone throw mud at me!

splat. you can create "toe" just bend the metal post a tad.
