Abstract
A locking mechanism for installing between a master cylinder and a brake line includes a housing having an internal bore, an inlet port, a passage, and an outlet port. A reciprocating piston is movable within the bore. A locking lever is coupled to the reciprocating piston for actuating the reciprocating piston. A fastener having an internal fluid passage for providing fluid communication between the passage and the master cylinder secures the housing to the master cylinder. The locking lever is moveable between a first position, wherein the hydraulic fluid can flow freely between the master cylinder and the brake line for engaging and disengaging the vehicle brake and a second position, wherein the hydraulic fluid is prevented from returning to the master cylinder for maintaining the vehicle brake in an engaged state.
