When you hit the brakes, weight is transferred to the front wheels. This causes the rear wheels to lose weight and can often lock up. A brake proportioning valve allows you to adjust the pressure rise in the rear brakes, giving you more control and better performance. Speedway Motors offers proportioning valves in a variety of styles and finishes to work for whatever your application is. We also offer award winning technical service to help dial in your brakes.
