Stainless Steel Brakes Sport R1 Plus Disc Brake Conversion Kit
The Sport R1 caliper was developed as a 54mm single piston aluminum caliper with a built in parking brake. Two different versions have been developed, one for cars and one for truck. The car version consists of a forged aluminum housing with stainless steel internals. With an improved design over the popular early GM rear caliper, the Sport R1 caliper uses the same brake pads, slider pins and bushings as this vehicle. The truck version of the Sport R1 (TRK1) features a larger billet aluminum housing, stainless steel internals and uses brake pads, slider pins and bushings from the front caliper of a 95-98 GM 1/2 ton truck. Current applications for this caliper are the 88-99 1/2 ton GM truck and SUV. A must have for better braking and elimination of that factory inchspongy pedal inch feel.
The Sport Twin 2 piston aluminum caliper was developed as a inchQuick Change inch direct replacement for GM's inchG-Body inch calipers. This 2 piston caliper has a forged aluminum housing with 2-38mm stainless steel pistons. Using the stock style G-body brake pads the 2 pistons of the Sport Twin caliper provide more clamping force and spread the load across the entire brake pad.
