Surface modification of OEM brake pad by scorching process

One of the main ingredients of a brake pad is resin material that acts as a matrix in the friction material. In the production process, the mixture of ingredients goes through pressure and temperature to increase the strength and integrity of the brake pad. However, baking process produces gases reducing the fade resistance of brake pads. The scorching process gets some millimeters of friction material surface porous resulting in slightly weakening the integrity of the components and as a result, friction materials can easily be contacted with the brake disc in the first braking condition. This means that the pads and discs need less time to get matched to each other. Having done scorching process, some properties such as hardness reduce, coefficient of friction whereas wear rate increase.
