Abstract
A method of manufacturing a brake pad comprising casting a back plate in a mould. The plate is formed with at least one integral projection which overhangs an adjacent surface of the plate. The mould is formed from frangible material and has a recess in the shape of the projection. The mould is formed from particulate material compressed around a projection made of resilient material which deforms to the shape of the projection. The resilient material is withdrawn to form the recess. Metal is cast in the mould including the recess. After solidification of the metal, the mould is broken away from the projection. The method also comprises pressing a mixture containing friction material and curable material against the plate including pressing the mixture around the projection so that it extends beneath the overhang and curing the curable material to form a block of friction material adhered to the plate.
