BENDIX SD-11-1357 manual Removal from Vehicle, Installing on Vehicle

3.Observe the stroke warning light. If the master cylinder piston seal leaks, the master cylinder, under sustained pressure, will slowly stroke until the stroke warning switch is activated.

REMOVAL FROM VEHICLE

1.Disconnect the hydraulic line from the delivery port of the master cylinder and allow the hydraulic fluid to drain into a suitable receptacle. The drainage may be expedited by removing the reservoir cover and gasket.

2.Disconnect the air line from the rotochamber, the fluid supply line from the master cylinder (in the case of remote mounted reservoirs), and the electrical connections from the stroke warning switch mounted in the head of the rotochamber.

3.Remove the nuts from the studs which hold the mounting brackets and remove the AH-4intensifier from the vehicle.

INSTALLING ON VEHICLE

1.Remount the AH-4intensifier, reconnect the air delivery line to the rotochamber and the electrical connections to the stroke warning switch.

2.In the case of remote mounted reservoir, reconnect the reservoir to the master cylinder.

3.Before adding hydraulic fluid, cycle the AH-4intensifier very carefully by making a very light brake application. The rotochamber should extend to full stroke and operate the stroke warning switch, causing the warning light to come on in the cab. This will test the stroke warning system. Release the application and reset the stroke warning switch.

4.Remove plugs, reconnect the fluid lines and bleed the master cylinder. The master cylinder itself may be bled by gravity by filling the reservoir and opening the bleeder fitting opposite the discharge port. When clear fluid flows from the bleeder fitting, it may be closed. If the rest of the system needs bleeding, it may be done by opening the appropriate bleed fitting and cycling the AH-4intensifier. Hydraulic brake fluid equivalent to DOT 3 specifications should always be used. Some AH-4intensifier units are designed to be used with mineral oil, in which case, the reservoir cover will clearly so designate. Rubber parts for use with mineral oil are color coded. Reservoir gasket diaphragm is green, seals and o-rings are brown.
