Braking force was translated into pressure that was sent to the rear brake cylinder. Also, the main brake cylinder was replaced. Moreover, a small brake cylinder is adequate for braking purpose. In turn the master brake cylinder develops hydraulic pressure in the wheels. Normally, the master brake cylinder is detached from the brake circuit. A dual-master brake cylinder was now included, while front disc brakes were optional. In an ICF BMBC coach, the brake cylinder is mounted on the bogie frame itself.
