Pressure adjustments range 100-1000 PSI and provide for a maximum decrease of 57% in line pressure. This adjustment allows you to fine tune the front to rear braking balance by proportionately decreasing the rear (or in some cases the front) brake line pressure. This product in most cases requires custom brake lines. The adjusting knob rotated all the way out will provide a maximum pressure reduction of 57%. Rotating the knob in will incrementally increase line pressure, up to full pressure. If the range of adjustment in the valve is not sufficient to properly balance the vehicle’s bias, changes to other components within the system may be necessary.
