How to Install a Dune Pressure Switch

The Baja Dune 150 is a dune buggy manufactured by Motorsports that is built for off-road excitement. The Dune 150 is powered by a 150cc four-cycle, electric-start engine with automatic drive. The Dune 150 also features four-wheel hydraulic brakes which are powered by a master cylinder on the back of the buggy. The brake-pressure switch is mounted to the master cylinder. Replacing the brake-pressure switch takes approximately 20 minutes.
