The hydraulic braking system is activated with a motorcycle type hand lever. It also features a locking mechanism that serves as a parking brake. When the lever is activated, hydraulic fluid flows to two calipers each located on the front forks. Brake pads in the calipers apply friction to each 3/16” thick x 7” dia disks which are directly attached to the axles thus braking all four front wheels. The primary use of the brake is to prevent the curb extruder from rolling when extruding down hill.
