IMPORTANT:
New Brake Chambers (18/2) have drain plugs instal-
led. Remove the bottom plug (see arrows). All other drain
holes should be plugged.

Before fitting the new Brake Actuator, the sealing
surface of the Caliper (see arrow) must be cleaned, and
the Spherical Cup (19) in the Lever must be greased
with white Grease RENOLIT HLT2 (Order no II14525).

The surface area of the flange must be clean.

IMPORTANT!

Do not use Grease containing molyb-
denum disulphate. Use only Bendix
Actuators recommended 19

Connect the air hose and check for leakage.

Make sure that the hose is not twisted and that chafing
is not possible.

IMPORTANT!
Road test vehicle before returning to service.
Test any air hoses or fittings removed
during maintenance work, using a soap
solution to check for leakage. A 1 inch
bubble in 1 minute is acceptable, otherwise
repair/replace components as necessary.
