3. BLEEDING OF HYDRAULIC BRAKES OF TRAILER

Bleed the system in the following way:

- Add missing volume of brake fluid into the equalising tank up to maximum level.

- Remove plug of vent screw (2) of hydraulic trailer control valve (1) located at the

left-hand front support of the cab silent-block.

- Slide a hose on the screw and put the hose other end at the bottom of a

transparent tank (3) partially filled with brake fluid. Place the tank minimally 300

mm above the vent screw. The vent screw must be permanently under pressure to

avoid aerating of brake system through the screw threads.

- Loosen the bleeding screws maximum by 1/4 turn.

- Fully depress the latched brake pedals to the stop and tighten the adjusting

screws.

- Release the brake pedals and repeat the process, until air bubbles cease escaping

from the hose.
