ABSTRACT:
The method includes the steps of forming separately a pair of spaced recesses in a carrier plate, the recesses having a parallelogram configuration other than a rectangle and a cross member therebetween providing an axis of symmetry, the recesses being symmetrically disposed with respect to the axis of symmetry to approximate a sector of a circle; pressing and age-hardening separately a plate of friction material having a thickness corresponding to the desired thickness of the friction pads; cutting at least a pair of friction pads from the plate having the dimensions and shape of the recesses; and placing and securing each of the pair of friction pads in a different one of the recesses so that the pair of friction pads are disposed symmetrically with respect to the axis of symmetry to approximate a sector of a circle.
