3.2. Braking s stem.
The caravan is equipped with an overrunning bra e which is automatically out of operation during the
car travelling bac . There is an additional hand operated bra e effective with both travel directions.
Bra e adjustment (see fig.2 and 3).
Bra e system adjustment range includes the gap between bra e shoes and a drum adjustment as well
as actuating rod adjustment.
Activities with the gap between the bra e shoes and the drum adjustment (see fig.2):
– till the caravan up unreel the wheels free rotation ability
– chec the bra e 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 bloc age 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 bra e shoes and drum adjustment.
Turning the pin on according an arrow which is mar ed on a brac et, effects in decreased gap between
the bra e shoes and the drum. Adjustment of actuating rod follows usually the successful adjustment
of the gap between the bra es shoes and the drum.
There is following action operated lever of the bra e:
– loose the manual operated lever of the bra e
– chec tension of the bra e 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 bra e and with hand lever pointed on the second step of the ratchet, both wheels
should be bra ed with the same sensed moderate force. With loose handler completely the wheels
must be rotated freely without notice resistant.
