TRAILER HYDRAULIC BRAKES
Connect the trailer or semi-trailer hydraulic brakes with the quick coupler marked with
an arrow.
The control of the trailer (semi-trailer) hydraulic brakes and the control of the tractor
brakes ensure synchronized braking effect of both the vehicles. Working pressure is
enforced by oil supplied from the hydraulic gear-type pump that works permanently.
The trailer brake control valve is controlled by brake fluid pressure from the main
brake cylinders depending on force that influences the brake pedal. Upon maximum
pressing down the brake pedal, pressure on the coupling head should be 12 - 15
MPa. The trailer brake valve prefers the brake function to the hydraulic function.
In the event of shocks when you press down the brake pedal, you have to bleed the
hose from the brake valve to the quick coupling.
When driving with trailer, the brake pedals should be connected and safe-
guarded with a lock!
When braking with one brake pedal, the trailer hydraulic brakes are out
of operation.
CONNECTION AND DISCONNECTION
OF QUICK COUPLINGS OF THE
TRAILER HYDRAULIC BRAKES
When connecting and discon-
necting the quick couplings you
should be aware of the rest of oil
that is kept in the quick coupling
plug or socket.
To protect environment you have
to remove the oil residues after
each disconnection of the quick
couplings with a textile rag.
