Parking brakes and emergency brakes

Rydahls supplies both parking brakes and emergency brakes. Sometimes a parking brake will only be used as a parking brake, but equally often the parking brake will also function as an emergency brake. There are a number of different variants of parking brake and emergency brake and therefore one must select the solution by vehicle type and the requirements of your brake system. In addition to the actual brake system we, of course, also supply pedals, controls, rigid brake hoses and other valves for a complete brake system.
