This adjustable rod replaces your stock nonadjustable brake push rod. This rod is located between your brake pedal and master cylinder. When the brake pedal is pushed this rod presses on the back of the master cylinder, starting the flow of pressure through the system. By installing this adjustable rod, it will allow you to take out any play in your brake pedal, therefore reducing the reaction time of pressure to the brakes. The end result is a more consistently high and hard brake pedal - a great confidence builder when diving deep into a corner. Will fit all years. Recommended for manual brakes only. Some years require fabrication of a pedal up-stop. Supplied assembled with extra long adjuster for reinforced firewalls; stock adjuster also included.
