REMOVAL FROM VEHICLE

1. Disconnect the hydraulic line from the delivery port of

the master cylinder and plug the line. Allow the hydraulic

fluid from the master cylinder to drain into a suitable

container. Remove reservoir cover to facilitate drainage.

2. Disconnect the air line from the air actuator and cover

the end of the air line.

3. Remove the electrical connection from the low level

indicator on the reservoir cover.

4. Remove the hardware that secures the mounting bracket

™

of the AH-1B

intensifier to the vehicle and remove the

complete unit.

INSTALLING ON VEHICLE

1. Install the hardware which secures the AH-1B

mounting bracket to the vehicle. Torque all hardware per

the vehicle manufacturer's recommendations.

2. Reconnect the air line to the actuator. Use a small amount

of thread sealant.

3. Reconnect the hydraulic line to the master cylinder.

4. Connect the electrical terminal from the low fluid indicator

onto the terminal on the cap of the reservoir.

5. Fill the master cylinder fluid reservoir using the type and

grade fluid specified by the vehicle manufacturer.

6. Bleed the hydraulic brakes following the vehicle

manufacturer's recommended procedure.

7. Refill the master cylinder fluid reservoir to replace fluid

lost during the bleeding procedure.

1. Drain the hydraulic fluid from the reservoir.

2. Remove the two Phillips screws and lockwashers from

the bottom of the reservoir located at the reservoir

mounting pad on the master cylinder next to the flange.

3. Remove the reservoir cap and retain. DO NOT

DISASSEMBLE CAP. Using a 1-1/4" socket remove the

retaining nut on the inside of the reservoir. Reservoir is

now free of the master cylinder. Remove the seal on the

bottom of the reservoir and discard. (Refer to Figure 6.)

4. Remove the compensating valve assembly from the

master cylinder by placing a crescent wrench across

the flats and turning counterclockwise. If only changing

the reservoir, do not remove the compensating valve

assembly as it cannot be replaced unless the master

cylinder is disassembled. The compensating valve must

be replaced as an assembly (Figure 7).
