• In-line pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel in both disc and drum brake systems
• The two pound (blue) valve is used in disc applications where the master cylinder is mounted below the horizontal plane of the calipers and fluid drain back occurs from gravity and vibration thereby causing excessive caliper piston retraction and a longer brake pedal stroke
• The ten pound (red) valve is used in drum applications to compensate for return spring tension and maintain wheel cylinder sealing in the drims
• Valves have 1/8" pipe threads on both ends
