Good To Know

Q: Do I need to bleed the brakes after installing this valve? A: Yes, any time the brake hydraulic circuit is opened for a proportioning valve install, the lines need to be bled at each wheel to remove trapped air.

Q: Can I mount this valve anywhere along the rear brake line? A: It is commonly mounted between the master cylinder and rear brake circuit, but the exact spot depends on your chassis layout and line routing.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
