Combination hydro-mechanical Parking Brake calipers use hydraulic pressure from the master cylinder for stopping power, and an internal mechanical lock within the caliper for a parking brake. CPB kits are built primarily for front-wheel drive vehicles, and select rear-wheel drive axles that are not well suited for internal shoe style parking brakes. The calipers are coupled with oversized two-piece rotor assemblies with aluminum hats and high friction BP-10 compound pads. CPB kits provide the correct balanced brake performance and matching style to compliment front big brake upgrade kits.
