Parking Brake Adjustment - Zetor PROXIMA POWER Z90 2012 Operator's Manual

If after the above mentioned adjustment
braking asymmetry between the right
and left side occurs, it will be necessary
to release the adjustment screw (7) of
the brake that brakes with a higher force
until the braking effect of the right and
left wheel equalizes; however, the screw
may only be released by 1/2 turn at the
most. If even after this readjustment the
braking asymmetry is not remedied, the
tractor brakes will have to be adjusted in
an authorized repair shop.

PARKING BRAKE ADJUSTMENT

1. Set the lever (4) to make the distance
between the console (K) and the front
of the fork on the lever (4) 109 mm
(the lever (4) should make the angle
of 20° with the vertical plane).
2. Screw the nut (2) on the seating sur-
face of the pin (3) without a play and p
re-stressing - the arms (5) must not
get depressed.
3. The adjustment procedure is the
same at the right as well as left side of
the tractor.
4. Use the nuts (8) to adjust the Bowden
cable of the parking brake lever in
such a way that with the 20° angle of
the lever maintained the parking
brake lever should be without any
play.
ADJUSTMENT
5. Lift and lower the parking brake lever
(1) several times to remove possible
mutual plays between its parts.
6. Check the setting of the parking
brakes system; if necessary adapt the
adjustment and check the tightening
of all the locking nuts (6), (8).
If after the above mentioned adjustment
any asymmetry of the parking brake ef-
fect between the right and left side oc-
curs, it will be necessary to release the
adjustment nut (2) of the brake with a
higher braking effect until the braking ef-
fects of the right and left brake equalize;
however, it is permissible to release the
nut (2) by 1.5 turns at the most. If even
after this readjustment the braking asym-
metry is not remedied, the tractor brakes
will have to be adjusted in an authorized
repair shop.
