APVDB - Adjustable Proportioning Valve with Brake Light Switch
The PROP-BLOCK is a precision-machined combination distribution block and adjustable proportioning valve in one.
The valve connects to the master cylinder and distributes brake fluid to all four wheels, while the adjustable proportioning valve regulates rear brake pressure, maintaining correct brake bias between front and rear brakes. A built-in switch activates brake lights when brake pedal is depressed.
Important: This is not a direct factory replacement for original blocks and some line modifications may be necessary.
