ABSTRACT:
A remotely controlled actuator for depressing a brake pedal so as to permit the brake system to be bled by a single operator. There is a pneumatic cylinder having attachment fittings mounted to its ends, and these engage the brake pedal and the rim of the steering wheel. Compressed air is supplied to the pneumatic cylinder by way of a portable control valve, so that as this extends, one attachment fitting depresses the brake pedal while the other reacts against the steering wheel. The portable control valve is connected to the cylinder by long, flexible air hoses, so as to permit the operator to move from wheel cylinder to wheel cylinder. A pressure regulator allows the operator to adjust the pressure which is exerted on the brake pedal.
