Abstract:
1. A disc brake comprising: a support member having a substantially rectangular body with a corresponding rectangular opening to define a first end that is separated from a second end by parallel first and second side walls, said first end having first and second perpendicular projections thereon aligned with said first wall and third and fourth perpendicular projections thereon aligned with said second wall, said support member being fixed to a housing of a vehicle to locate said first and second walls in parallel alignment corresponding first and second faces on a rotor, said first wall having a first bore for receiving a first piston to define a first chamber, said second wall having a second bore for receiving a second piston to define a second chamber; a first friction member having a first carrier plate with a first radial projection and a second radial projection thereon located mid-way between a first end and a second end; a second friction member having a second carrier plate with a third radial projection and a fourth radial projection thereon located mid-way between a first end and a second end; and linkage means for connecting said first projection on said first friction member with said first perpendicular projection on said support member, second projection on said first friction member with said second perpendicular projection on said support member, said third projection on said second friction member with said third perpendicular projection on said support member and said fourth projection on said second friction member with said fourth perpendicular projection to align said first friction member adjacent said first piston and said second friction member adjacent said second piston such that on presentation of pressurized fluid to said first and second chambers said first and second piston an actuation force is created to simultaneously move said first friction member into engagement with said first face on said rotor and second friction member into engagement with said second face on said rotor to effect a brake application.
