After waiting over a month for an ï¿½lbsï¿½ (i live in rural Texas and itï¿½s a two hour drive) to do some maintenance including replacing brakes and a tuneup i decided to learn to fix more problems at home.
Different rotors from different brands have micrometer differences but itï¿½s enough to run and squeak if you donï¿½t reset the pads. I tried using credit card shims , moving the pad mounts, but nothing was 100% effective. A friend said they had the same issue and the lbs they used told them but the park tool. He said it worked wonders so i bought my own. First try NO SQUEAK!
Have used it on my other bikes and it is the most consistent fix for rubs Iï¿½ve encountered. If your rotor has warping issues it wonï¿½t fix that, you may need a truing tool if itï¿½s even fixable.
A cheap addition to your workplace that can save you headaches and cash when pads and rotors last longer.
