Superior Brake Residual Valves

RPC Residual Check Valves eliminate spongy pedal feel by retaining brake line pressure and keeping the pedal firm. The valve stops brake fluid from draining back into the master cylinder; this keeps your caliper pistons and brake shoes from fully retracting, so your brake system stays primed without brake drag. The result is a firmer brake pedal that engages quicker & increases response. Valves are available in 2-psi for disc brakes and 10-psi for drum brakes (drum applications require more pressure to compensate for return spring tension).
