Abstract
An all terrain vehicle (ATV) with a dual hydraulic brake system. The brake system includes a first master cylinder, a pair of front hydraulic brake units, each one being associated with one of the ATV's front wheels, a rear brake unit associated with the ATV's rear wheels, a hand-operable brake lever mounted to the handlebars and operatively connected to the first master cylinder, and hydraulic linking the first master cylinder to the brake units so that when the brake lever actuates the first master cylinder brakes are applied to both the front and the back wheels of the ATV. A second master cylinder is connected to a second hand or foot-operable brake lever carried by the chassis near one of the footrests. Hydraulic connections link the second master cylinder to only the rear brake unit so that operation of the second brake lever actuates only the rear brake. The rear brake unit preferably is a disc brake that includes a caliper body and a stepped piston disposed within a stepped bore formed in the caliper body. The stepped piston and the stepped bore together defining two separate hydraulic fluid chambers. The first master cylinder is connected to one of the hydraulic fluid cham…
