PART NUMBER(S):
Fleet Products: RC-01 (New/Remanufactured) | OE: Lucas Girling RC-01, RRH01K
DESCRIPTION:
Model: Inline Residual Check Valve – 5/16″ Port (Lucas Girling Style)
Vehicles: Ford LN/FT-Series trucks, Freightliner medium-duty trucks, and commercial buses with Lucas Girling hydraulic brake systems
• Maintains 3–10 psi residual pressure in hydraulic brake systems to prevent seal leakage
• Inline installation between master cylinder and rear wheel-end “T” fitting
• Housing available in steel or brass with corrosion-resistant finish
• Supports service and parking brake hydraulic actuation in drum brake systems
Applications: Is this residual check valve right for your vehicle? Yes—engineered for Lucas Girling hydraulic systems in Ford, Freightliner, and bus applications. Keeps expander and adjuster cylinders sealed and operational by maintaining 10–14 psi in the circuit. Required for proper system function and warranty compliance on Lucas-style hydraulic drum brake assemblies.
Designed for use with Lucas Girling adjuster/expander cylinders (201179X, 201183X, 201180X, 201184X)
