Abstract
The output shaft of an automotive friction clutch may be braked during shifting of the transmission into higher gear by a brake disc secured against rotation on the shaft and axially moved into engagement with a friction member on a non-rotating element of the vehicle by a pressure plate backed by a resilient wall of a chamber to which a pressure fluid is admitted when the driver depresses the clutch pedal further than needed for only disengaging the clutch. A switch closed by the pedal opens a solenoid valve in the pressure line to the chamber.
