Proportioning Valve

Here is a close up on the Knob-Type Proportioning valve. This valve has ports for front and rear lines in from the master cylinder, two front outputs, one for the front right, and one for the left, one output for the rear brakes, and a pressure switch for the brake lights. The knob can be used to adjust the pressure to the rear brakes so they don’t lock up to early. We like to set the proportioning valve so that the rear brakes lock up just before the fronts in dirt or gravel.
