Hydraulic brakes of trailers
FHD14N064
Connect hydraulic brakes of trailer or articulated trailer to the quick couplings marked by an arrow.
Control of hydraulic brakes of trailers (articulated trailers) and control of tractor brakes is done so that the
braking effect of both vehicles is synchronized. Working pressure is derived by oil supplied by non-switched
on/switched off gear pump of hydraulics. Brake valve of the trailer is done by the pressure of brake fluid from
main braking rollers depending on the force effecting on the brake pedal. The pressure on clutch head must
be 12 - 15 MPa with maximum depression of brake pedal. Brake valve of trailer prefers the function of brakes
to the function of hydraulics. If there are shocks when foot brake pedals are depressed in the pipeline of
hydraulic circuit, it is necessary to bleed the hose from the brake valve to the quick coupling.
When driving with connected trailer or articulated trailer, the pedals of foot brake must be
connected and secured by a valve! When braking with one brake pedal, hydraulic brakes of the trailer
are not active.
Connecting and disconnecting quick couplings of trailer hydraulic brakes
When connecting and disconnecting quick couplings, take increased care with regard for
remaining oil which remains in the socket or in the plug of quick coupling. For ecological reasons, it
is necessary to remove this remaining oil after every disconnection of quick couplings with any
textile material.
Stopping the tractor - manual brake
Stop the tractor slowly under standard conditions. Shortly
before stopping:
1. Depress the clutch pedal.
2. Shift the main gear shifting lever to neutral position.
3. With every stopping, secure the tractor against
spontaneous dead start by manual brake.
