Bedding in and/or burning in the brake pads - how to cure disc brakes squeal.

The growing interest in disc brakes even in road bikes should be accompanied by increasing knowledge on disc brake technology.

Other cyclists including the pro, dislike disc brake for the additional weight and more maintenance costs and processes.

One of the never ending problems in disc brakes is brake squeal.

The usual cleaning the brake pads and discs with alcohol and/or sand papering the pads and the disc, there are other things I did not get to know -  the burning in and or bedding in the  brake pads.  This must be done:

     1. When new brake pads or discs are installed;
     2.  Immediately after the cleaning of the pads and the disc

You can do the bedding in either by:

1.  Riding down a long hill with brakes engaged 75%.   You are literally burning the disc and the pads with this process

2.  Ride on a level ground using the largest rear cogs, and engaging the  brakes slightly (same 75%)  The squeak may recur but eventually as the disc and pads bed in the squeal should disappear.
