Adjustable Brake Bias Valve with -3 AN Outlets

Brake Bias Proportioning Valve with -3 Fittings.

An adjustable brake bias valve is a component used in vehicles, particularly in motorsports, to control the distribution of braking force between the front and rear axles. Brake bias (or brake balance) refers to how the braking force is split between the front and rear brakes. Adjusting this balance can have a significant impact on the vehicle's handling and braking performance.

Key Features and Functions:
• Brake Bias Control: The primary function of the adjustable brake bias valve is to alter the proportion of braking force applied to the front and rear brakes. This is particularly useful in vehicles where the optimal brake balance changes under different conditions such as track surface, speed, load, or cornering forces.
• Adjustment: The valve allows drivers or technicians to adjust the brake bias while driving (in motorsports, for instance) or during setup. The driver can fine-tune the balance by turning a knob or lever inside the cockpit, giving them the ability to adapt to changing conditions or preferences.
• Improved Performance and Safety: The ability to adjust brake bias allows for better control over the vehicle’s handling. For instance: More front bias (more braking force to the front brakes) is often used to improve stability and reduce the risk of rear-wheel lockup during hard braking. More rear bias (more braking force to the rear) can increase rear-end rotation, helping in cornering or aggressive driving, but it can increase the risk of the rear wheels locking under heavy braking.

Applications: In motorsports, particularly in racing, where conditions change rapidly, an adjustable brake bias valve allows teams to adapt to these conditions to optimize braking performance. It’s also used in some high-performance street cars to allow for adjustable brake balance.
