Installation of an adjustable proportioning valve is necessary when the reduction of brake line pressure is required to facilitate the balancing of front-to-rear brake bias.
Both inlet and outlet are 1/8-27 NPT and come with compression fitting adapters.

This is use full in adjusting rear disc brakes for optimum performance.
Some front disc brake conversions may benefit from this unit as well.
