Brakes Sqeaking, Need Help !! . . . . . .Nomatt
May 27, 2003 10:11 AM
just got my first road bike, and when i do any hard braking, the brakes make a REALLY loud sqeaking noise. i have had the bike a week and have ridden about 40 miles, during which i had to brake hard about 4 or 5 times. is this supposed to happen, is there a breaking in period for the brake pads after which they will quiet down? or is something not adjusted correctly and i should fix it? thanks for any help.

couple of things:
(1) your pads or rim braking surface could be contaminated with with unnoticable amounts of lubricante, oil etc clean the brake pads and rim braking surface throughly.

(2) What type of brake calipers and pads are they cermaic, Campy, Shimano? the brake pads should be toed in ever so slightly so the front part of the pads contact the braking surface first.

My hunch is your pads are contaminated but that is just my hunch.
Hope this helps.

Agree--a tiny bit of toe-in, and VERY clean surfacesSilverback

That will solve the problem at least 90 percent of the time, in my experience. Set the pads so the leading edge touches the rim 1-2mm before the trailing edge (they'll pull flat under braking). Then make sure everything is clean--you can use 100 or 150-grit sandpaper lightly on the pads, to remove the top layer of material, and scrub the rim walls with alcohol or detergent on a very fine steel wool pad or one of those Scotchbrite scrubbers. If you use detergent, be sure to rinse it off.

Clean off your pads and rims with soap, hot water and a abrasive pad (I use the green pads sold to clean pots and pans).

If that doesn't work try toeing them in a little.

Lastly, if nothing else works, replace the pads. Shimano makes two kinds of pads -- high performance and regular. The high performance ones work poorly IMO and make noise. I installed some by mistake once and ended up tossing them.

Properly functioning brakes are important.
