Claim:
1. A brake pad apparatus for engaging a rotor of a brake assembly of a vehicle to reduce the speed of the vehicle, said brake pad apparatus comprising: a backing plate having an inside surface and an outside surface extending along a first plane, a liner connected to said inside surface of said backing plate for contacting the rotor for creating a frictional force against the rotor to reduce the speed of the vehicle; an insulating layer having a thickness and connected to said outside surface of said backing plate for providing heat and noise insulation to said backing plate during contact of said liner against the rotor, a plurality of projections spaced from one another and extending from said outside surface of said backing plate and through said insulating layer and past said thickness of said insulating layer to an engagement surface for engaging a piston and preventing the piston from engaging said insulating member, said inside surface and said outside surface of said backing plate extending between a pair of sides disposed on opposite sides of a second plane extending perpendicularly to said backing plate and halfway between said sides, and said plurality of projections including a pair of outside projections each disposed in an arcuate shape and extending between ends to present a concave inside opening to said second plane with said outside projections spaced from one another and being mirror images of one another equally on opposite sides of said second plane whereby said concave insides are bowed away from one another.
