What is a pre-bedded brake pad?
Some brake pad manufactures offer a pre-bedded pad and/or a pre-bedding service. Pre-bedding is performed by placing a pad in a caliper and running them with a mechanical driven rotor. The rotor and pads are then slowly brought up to temperature and allowed to cool down over several cycles. This process simulates on track situations while the two surfaces mate correctly. While this process can be very expensive, it greatly reduces the break-in time prior to pad purchase. In most cases the rotor and the pad would then be sold as a matched set.
