3.2. Braking system.
The caravan is equipped with an overrunning brake which is automatically out of operation during the
car travelling back. There is an additional hand operated brake effective with both travel directions.
Brake adjustment (see fig.2 and 3).
Brake system adjustment range includes the gap between brake shoes and a drum adjustment as well
as actuating rod adjustment.
Activities with the gap between the brake shoes and the drum adjustment (see fig.2):
– till the caravan up unreel the wheels free rotation ability
– check the brake actuating line which should be hanged down freely, if not, decrease its tension
– remove a covering cap of the gap adjustment system protection
– using a screw-driver turn the pin on until you reach the drum rotation blockage in forwarding direction
– turn the pin on in reverse direction until you reach the drum free rotation without any friction
Figure 2 : The gap between brake shoes and drum adjustment.
Turning the pin on according an arrow which is marked on a bracket, effects in decreased gap between
the brake shoes and the drum. Adjustment of actuating rod follows usually the successful adjustment
of the gap between the brakes shoes and the drum.
There is following action operated lever of the brake:
– loose the manual operated lever of the brake
– check tension of the brake actuating line and adjust it at stable adjusted transition, in this purpose,
turn the adjusting nuts (6) and (7), located on the line end (4), until you reach a right angle between
a cross piece (5) and an actuating rod (1)
– adjust on overrunning device (detail A fig.3) both nuts (3) of the actuating rod (1) until you reach the
gap of 1 mm between front surface of the nut and a thrust plate of the spring, located in the cylinder
inside.
Under properly brake and with hand lever pointed on the second step of the ratchet, both wheels
should be braked with the same sensed moderate force. With loose handler completely the wheels
must be rotated freely without notice resistant.
