Final answer:
To install a conventional clutch brake, the transmission must typically be removed to gain access to the clutch assembly. The clutch brake is located behind the clutch assembly, near the transmission input shaft.
Step-by-step explanation:
To install a conventional clutch brake, the component that must typically be removed in the vehicle is the transmission. The clutch brake is a device used in manual transmissions to prevent gears from grinding when shifting into first gear from a stop or shifting between reverse and first gear while the vehicle is stationary.
In order to access the clutch brake, the transmission is often required to be detached from the engine assembly because the clutch brake sits right behind the clutch assembly, adjacent to the transmission input shaft. Without removing the transmission, it can be very difficult or impossible to properly install, adjust, or replace the clutch brake.
