Hydraulic Braking System Wheel cylinders Multi- function cylinders: These are multi-function cylinders designed to operate lever-type mechanical brakes with a double function, that is service braking and parking braking. Service and parking brake are in the same mechanical lever. The force acting on the lever is the biggest one between the service brake and the parking brake (the forces don’t add to each other). By means of a suitable device, the parking brake can also act as an emergency brake.. Applications: Big size vehicles with mechanical brakes. Negative cylinders: These are spring cylinders for hydraulically operated parking brake. Safim offers a wide range of negative parking brake
