| titleOfInvention | Vehicle brake leak testing system and method |
| abstract | A system for leak testing a closed vehicle brake system by actuating pistons in a master cylinder. A fluid motor in a separate pneumatic plumbing circuit is automatically sequentially actuated extending a plunger engaging the pistons to pressurize the brake fluid in various degress as prescribed in a predetermined test procedure. A solid state electrical control circuit automatically sequences valves in the pneumatic fluid circuit providing desired brake fluid pressures during the leak test. The control circuit includes a digital converter applying a voltage determined by the position of the master cylinder piston at the beginning of a test time period which is continuously used as a reference in opposiion to a position responsive voltage regulated by the linear potentiometer during the test. The control circuit can include a selector switch to operate one of a plurality of separate pneumatic plumbing circuits, each being suited for a particular master cylinder design. In this manner, fluid leakage is accurately and immediately sensed and a fault signal is energized and the test aborted when unacceptable leakage occurs. |
