Brake surface "shudder"

[Prozac]

I need assistance / advise please . . .

 

As per photos , My training wheels has a small "chip , tear , piece " what ever you call it on the braking surface causing a "shudder" when I brake . . .

 

How can I fix this ?

I had something similar (I think), I had a small chip with a tiny bit of the rim protruding on the rim which caused more a of "tick tick tick" sound when braking.

 

I just took some fine sand paper and sanded down the protruding bit of the rim / chip and it seemed to do the trick.

Have also sanded down a rim when I had a crash which left scratches on the rim. use a flat block with fine sand paper as you do not want to create a valley where you are sanding,

 

It doesn't take many passes with the sand paper to smooth out the protruding bit of metal that is causing the noise and shudder when it passes the braking blocks.

Shudder is more likely to be from the caliper not centered evenly or the pads not aligned properly. Depending on your calipers you usually have a small screw on the one side that you use to set the caliper so that the gap between the rim and pad is the same on both sides. You may have to loosen the bolt holding the caliper to the frame to center it if the screw does not move it enough. Your pads also should be aligned with some "toe in". To do this loosen the pad, hold a business card between the back end of the pad and the rim and with someone activating the brake tighten the pad in this position, making sure that the pad is well positioned on the rim - clearing the tire and balancded with the pad on the other side.
