ABSTRACT:
A parking brake mechanism for a motorcycle having a rear brake pedal which is to be depressed for applying a brake on a rear road wheel. An annular ratchet wheel is rigidly connected to the pivoted end of the rear brake pedal for simultaneous rotation therewith, and one or more pawls pivotally mounted within the ratchet wheel are spring biased into engagement with teeth formed on its inside surface. Normally, the pawls are held out of engagement with the ratchet teeth by a rotary cam ring. Upon angular displacement of this cam ring relative to the pawls, the ratchet mechanism functions to permit the rear brake pedal to be depressed but to prevent its return motion. The cam ring can be actuated either by a retractable footrest or by a hand lever on the steering handle of the motorcycle.
