When you install new brake pads, which are typically replaced at the same time as new brake rotors, it’s a good idea to break-in the brakes using a “bedding” procedure. A bedding procedure involves a series of controlled stops in order to transfer an even layer of brake pad material onto the new rotors. The reason why you want to do this is to prevent uneven “pad transfer”, which can cause you to experience wobble or vibration while you depress the brake pedal.
