Braking system

The braking system is composed of service brake system (i.e., the foot brake) and parking brake system (i.e. the hand brake), after treading the foot brake valve, compressed air  in the air storage tank is interlinked through relay valve with the brake chamber of the rear axle, achieve brake function. Release the foot brake valve, brake chamber and atmosphere are interlinked, relieves the foot brake; When pulling out the hand brake valve stem, relay valve acts, all compressed air in brake chamber is exhausted, hand brake chamber spring let brake shoe press the brake drum, achieve the parking brake.
