How to Convert ABS Brakes to Non-ABS Brakesby Jack Hathcoat
Converting an automobile or truck from anti-lock brakes to standard brakes requires removing the vehicle's anti-lock control unit and directly plumbing the brake lines from the master cylinder to the individual brakes on each wheel. Removing the brake system's electrical wiring and related components is not necessary. While each wheel sensor can be removed, the sensors will not interfere with brake operation if left in place.
Raise the hood of the car and disconnect the brake lines at the anti-lock brake control unit by using a flair-nut wrench. Note the routing of the lines from the master cylinder. Each of the lines will be rerouted to the appropriate wheel. Unbolt the control unit from the mounting bracket with a socket wrench, and set it aside for proper disposal.
Reroute the brake lines from the wheels to the master cylinder. In some cases, the lines will be too short. You can either purchase new lines or fabricate lines with a brake line bending tool and a flair tool. Install the front brake lines in the section of the master cylinder that is serviced by the larger of the two brake fluid reservoirs.
Bleed all the brakes to remove trapped air. Have an assistant pump the brakes and then hold steady pressure on the pedal. Open the bleeder valve with a wrench, then close the valve after the air has escaped. Have the assistant follow the same procedure and open the valve. Continue this process until there is no air present and only clean brake fluid exits the valve.
