Abstract:
1. A disc brake comprising: a support member having a base, an end member laterally spaced apart from said base, and spaced apart first and second beams that extend between and connect said base to said end member, said end member having third and fourth beams that extend there from toward said base, said first and said third beam defining a first rail with first and second grooves therein and said second beam and said fourth beam defining a second rail with third and fourth grooves therein, said base being configured to be fixed to a vehicle housing with said first, second, third, and fourth beams perpendicular to first and second faces on a rotor; a first friction member having a first carrier plate retained between the first groove in the first rail and the third groove in the second rail; a second friction member having a second carrier plate retained between the second groove in the first rail and the fourth groove in the second rail; a caliper defined by a caliper housing having an actuation section with a first leg extending there from, a first bore located in the actuation section with a piston retained therein to create an actuation chamber and a second leg that is connected by a bridge to the actuation section, said first leg having a second bore that extends there through; and a pin that extends through said second bore in said first leg of the caliper and is connected to the base of the support member such that the piston is aligned with the first friction member and the second leg is aligned with the second friction member, wherein said caliper and said pin are configured so that, in response to pressurized fluid being presented to the actuation chamber, said piston moves said first friction member into engagement with the first face on the rotor and acts on the caliper housing to cause the first leg to slide on said pin and move the second friction member into engagement with the second face on the rotor to create a clamping force on the rotor, and wherein said caliper and said pin are further configured so that, in response to creation of the clamping force on the rotor, the caliper housing is caused to rotate on said pin and bring the first and second carrier plates into engagement with one of the first and second rails.
