Brake bias valveThe OBP brake bias valve is ideal for adjusting brake balance especially on cars with upgraded brakes.
The bias valve is installed in the rear brake line, and adjusting it restricts the pressure going to the brakes.
Ideally the brakes are adjusted so that they lock at the same time, or what ever the driver prefers. We definitely suggest this product for cars with upgraded brakes to get maximum braking potential.The line can also be completely closed with the OBP brake line lock. For fluid, we suggest Castrol react performance brake fluid
