Brand: Optimum Balance Products (OBP)
The compact OBP Brake Bias Valve allows the driver to rapidly select 5 distinct and repeatable settings for brake bias. This is a great tool for cars which must run a single master cylinder instead of a bias bar. Install the valve in the rear brake line to reduce the amount of pressure at the rear brakes, reducing rear lockup under heavy braking.
The maximum reduction of output pressure is approximately 60% of the input pressure. The handle can be oriented in any direction with respect to the base for ease of installation. The billet aluminum housing has 1/8 NPT female inlet and outlet ports.
