Abstract

[Object] To provide the disc brake pad including the friction material having the friction surface with the scorch treatment that can provide sufficient braking effectiveness while preventing the fading phenomenon at the initial stage of the disc brake pad usage. [Means to Resolve] In the disc brake pad including the friction material having the friction surface with the heat history due to the scorch treatment, the friction surface has the mixed areas including the area with the large heat history of the scorch treatment and the area with relatively small heat history of the scorch treatment. The following formula needs to be satisfied where the reduction rate of the mass of the inside of the friction material without the heat history due to the scorch treatment when performing the thermogravimetric analysis of the friction material at 500 centigrade is A, the reduction rate of the mass of the friction surface area with the largest heat history due to the scorch treatment when performing the thermogravimetric analysis at 500 centigrade is Band the reduction rate of the mass of the friction surface area with the relatively small heat history due to the scorch treatment relative to the friction surface area with the largest heat history when performing the thermogravimetric analysis at 500 centigrade is B  Formula:
