- Maintains 10 psi residual line pressure required for drum brakes
- Overcomes drum spring tension for immediate shoe response
- Machined aluminium construction provides high structural strength
- Prevents fluid siphoning in under-floor cylinder applications
- Simple inline installation with standard flare fittings
Engineered specifically for drum brake systems, this 10-pound residual pressure valve maintains hydraulic tension against drum return springs. It prevents fluid bleed-back into the master cylinder, ensuring immediate shoe engagement upon pedal stroke.
