The Sportsman braking system uses four Matco master cylinders. Each brake pedal, when tilted forward, applies the brake on left or right Grove brake calipers. The pilot and co-pilot brake pedals are connected to each other so either pilot or both can apply even or differential braking. Since the nose wheel freely swivels through a wide arc and is not directly connected to the brake pedals, using the brakes is necessary to help steer the plane when taxiing. We ran into several trouble spots during the installation of the 4 master cylinders. The left co-pilot master cylinder had the brake line connections facing inward. In that position, they interfered with installing the center tunnel cover. So we reversed that cylinder and gained the clearance we needed. We mounted the reservoir for the brake fluid on the co-pilot's side to a bracket attached to the cage tubing. That position allows the viewing of the reservoir during the process of bleeding the brakes and making sure sufficient fluid is in the reservoir.
