What is the bed-in procedure (brake preparation)?

When pads and rotors are new, they have to be “bed in” before they reach their full braking potential. This is achieved by first accelerating the bike to a moderate speed and then firmly applying the brakes until you are at walking speed. Repeat this process 20 times. Then accelerate the bike to a faster speed and apply the brakes until you are at walking speed. Repeat this process ten times. It’s important that during this process you never come to a complete stop or lock up the wheels at any point. The idea behind bedding in a brake is to evenly distribute pad material across the rotor to improve the coefficient of friction between the two components. Coming to a complete stop causes a build up of pad material in one spot that can lead to pulsing and noisy brakes.
