143-2541: 25.387mm Outer Diameter Slave Piston

The Slave Piston is a type of piston that is connected to a larger piston and moves in response to the movement of the larger piston used in the engine brake. When the engine brake is engaged, the slave piston is activated, causing it to move upward against the force of the valve springs. This upward movement opens the exhaust valves before the compression stroke begins. As a result, a portion of the compressed air is forced out of the cylinder, creating resistance and slowing down the engine. Attributes: • Withstands high temperatures without deformation • Provides resistance to abrasion Applications: The Slave Piston is used to actuate the exhaust valves during the engine's compression stroke, creating a braking effect.
