Method of manufacturing disk brake pad.

摘要

A method of forming a disk brake pad having a friction member composed of a bonding layer having a low porosity and a matrix layer having a high porosity and laminated on the bonding layer. This method requires no pre-forming step. A material formed by pelletizing a mixture of components for the friction member and a non-pelletized material are fed one after the other into a cavity defined by a mold and the back plate and hot-pressed. Since the pelletized material is compacted beforehand, the bonding layer formed from this material shows a sufficiently low porosity, so that this layer can prevent water contents from infiltrating therethrough. Thus, the back plate is less likely to develop rust. Also, the bonding strength between the back plate and the bonding layer improves. Further, since pelletized material forming the bonding layer penetrates into the matrix layer in a complicated manner, the bond strength between the bonding layer and the matrix also improves. <IMAGE>
