   Sammanfattning : The Retarder is one of the main components in Scania's trucks' braking system and is used to brake down the truck and for maintaining a steady speed on descents. This Master's Thesis aims to investigate if the current system which uses a proportional valve to control the air pressure in the Retarder, can be replaced with two on/o® solenoid valves and a pressure chamber to control the air pressure, which would result in a cheaper and more robust system.
