5.4.4.3 Operation 33. Check / adjustment of service brake control
ATTENTION: IT IS REQUIRED TO CHECK AND ADJUST THE BRAKE SYSTEM
AS WELL AS ELIMINATE ANY FAILURES IN IT ONLY WITH THE ENGINE OFF AND
THE TRACTOR PLACED IN HORIZONTAL POSITION AND FIXED BY MEANS OF
CHOCKS UNDER THE WHEELS WHICH EXCLUDE THE TRACTOR SPONTANEOUS
MOVEMENT! ONLY DEALERS ARE ALLOWED TO MAKE ADJUSTMENTS TO THE
BRAKE SYSTEM AND ELIMINATE ANY FAILURES!
When depressed with a force of 120 to 130 N, a full travel of the right brake pedal
shall stay within 105 to 115 mm, and a full travel of the left pedal shall be 5 to 20 mm less
than the full travel of the right pedal under the application of the same force.
If the full travels of the right and the left pedals do not correspond to the specified
values, carry out adjustment of the service brake control.
The service brake control shall be adjusted as follows:
- set pads A (figure 5.4.35) of both pedals in one and the same plane with an accu-
racy of 2 to 3 mm (it is allowed to align the pads by bending legs B);
- undo locknuts 3 (figure 5.4.35) of adjusting bolts 2;
- screw bolts 2 into the yokes or screw them out as much as to make the full travel
of the right pedal stay within 105 to 115 mm under the application of 120 to 130 N force,
while the full travel of the left pedal be 5 to 20 mm less than the right pedal travel to ensure
simultaneous response of the brakes with the pedals interlocked.
- tighten locknuts 3 with a torque of 75 to 95 Nm.
