Patent ID: 7703581

Claim:
A disc brake having a support member fixed to a stationary member with first and second spaced apart rails that extend there from to receive and align a first friction member with a first side of a rotor and align a second friction member with a second side of the rotor and a caliper having a housing with an actuation chamber that receives pressurized fluid from a source that acts on a piston arrangement and the housing to create a braking force that respectively moves the first and second friction members into engagement with the first and second sides of the rotor to effect a brake application, said disc brake being characterized in that said piston arrangement includes a first cylindrical body having a face with a first radial groove therein; in that said first friction member includes a carrier having a second radial groove that is located between a first carrier end and a second carrier end; and by linkage means having a first linkage end retained in said first radial groove and a second linkage end retained in said second radial groove, said braking force from said piston arrangement being communicated through said linkage means to said carrier for moving said first friction member into engagement with the first side of said rotor such that the first carrier end is rotated into abutment engagement with said first rail to oppose the rotation of the rotor, wherein rotation of the carrier into abutment with the first rail causes said linkage means to pivot in said second radial groove an amount sufficient to cause the housing of said caliper to mechanically move said second friction member into engagement with the second side of the rotor.
