Racing Power Co. R4513 Universal Residual Check Valve 2 PSI

The Racing Power Company R4513 is a universal residual check valve designed to maintain proper brake system pressure in vehicles equipped with disc/drum brake combinations or custom brake setups. This valve maintains a 2 PSI residual pressure in the brake lines, preventing fluid from draining back to the master cylinder and ensuring immediate brake response.

Key Features:

• Universal fit design works with most brake systems
• Maintains 2 PSI residual pressure to prevent brake fluid backflow
• Blue anodized aluminum construction for durability and corrosion resistance
• Prevents brake pedal fade and spongy pedal feel
• Essential for drum brake systems and long brake line applications
• Inline installation between master cylinder and brake lines

This residual pressure valve is particularly important in applications with drum brakes or where brake lines run above the master cylinder level, as it keeps the lines filled with fluid and wheel cylinders properly positioned. The compact design allows for easy installation in tight engine compartments.
