Brakes on the "CERV-I" are similar to the HD type available on the Chevrolet Corvette. Sintered iron linings are used with fin cooled drums, and the brake drum webs are lightened by drilled lightening holes which also permit the flow of cooling air. The brake drums are cast aluminum with cast-in iron braking surfaces. The rear brakes are inboard mounted next to the differential so that braking torque is transmitted directly to the frame without influencing any of the rear wheel articulating members. Braking effort distribution is 57% front and 43% rear to take advantage of the superior braking characteristics of the weight distribution afforded by the rear engine type vehicle. The brakes may be actuated by either one of two pedals so that the driver may use either foot depending on the particular driving situation. An unusual brake master cylinder utilizes two pistons operating in series so that it either the front or rear brakes fail the remaining brakes can be actuated.
