One of the best ways to get the most out of your brakes is to adjust the brake proportioning or bias. The ideal brake bias depends on your ride height, the amount of traction you have (both due to your tyres and the surface you're driving on), and the specification of your braking system. You always want the front brakes to lock up first for stability reasons, but Mazda was extremely conservative and so the rears never have a chance to make much of a contribution. This adjustable proportioning valve allows you to adjust your brake bias for the perfect setup. The valve allows you to adjust the rear line pressure from 43% to 100% of the front.
