Cobalt Friction XR4 Brake Pads are a medium torque compound sharing the same application basis as the XR3, but at lower overall friction levels. Slightly rising torque profile at low to moderate line pressures, while transitioning to a virtually flat profile at higher line pressures for unmatched friction stability.
