Open the CIPO recordAbstract From the Canadian patent
A brake assembly for a vehicle is mounted directly on the vehicle frame with the brake caliper straddling a brake disc carried directly on the vehicle drive line. The brake is spring applied to grab the disc and to prevent rotation of the drive line. Air pressure is used to release the brake such that loss of air pressure as when an air hose ruptures or when the air reserve is consumed by usage will permit the spring to lock the brake and prevent rotation of the drive line. The brake can be applied when the engine is running by releasing the air pressure on the brake. - 1 -
