DESCRIPTION

The AH-1B™air hydraulic intensifier is a hydraulic brake, power booster which utilizes compressed air for its power assist. Its function is to convert air pressure to hydraulic pressure for use in the brake system.

The AH-1B™intensifier consists of three major component groups; a specially designed type 30 air actuator is bolted to a single piston master cylinder which incorporates an

integral brake fluid reservoir. A bracket installed between the actuator and master cylinder provides a means for mounting.

A float actuated, low fluid level, on/off electrical switch is incorporated in the reservoir filler cap assembly. A two “prong” connector is provided to permit the installation of a vehicle electrical cable assembly. Switch actuation occurs when the reservoir fluid level drops below the “minimum” level marking on the reservoir.
