These residual check valves help keep the brake system functioning properly, while also helping to retain a firm pedal. Maintaining pressure prevents fluid from returning to the master cylinder, when the master cylinder is positioned lower than or close to the same height as the calipers or wheel cylinders. Proper system pressure also keeps pistons and wheel cylinder seals expanded, creating a positive seal, and brake pads seated against the brake disc. These 2lb valves are suitable for disc brake systems, a 10lb version is available for drum brake systems - please contact us for availability.
These valves have 3/8 UNF convex seat female ports so can be used with no lead 3/8 UNF male tube nuts and hard line or 3/8 UNF inverted flare hose ends or adapters.
