ADJUSTMENT OF SERVICE BRAKE

Before adjustment of service brake the parking brake lever must be in disbraked
position and there must be a play between nut (1) and pin (2) in lever of disc brake
(3). In case you will find this system without a play, loosen gently the nut (1). Lift both
rear tractor wheels and let turn one wheel by means of your helper by hand.
Simultaneously tighten the adjusting nut (4) so long the wheel can not be turned by
hand. Do not tighten more. After blocking the wheel loosen the adjusting nut by 5/6
of turn (5 flats of nut) and check for turning the wheel. After this basic adjustment
check for efficiency of service brakes and for the brake effect of both wheels. If the
asymmetry of brake effect appears between left and right brake the adjusting nut (4)
of brake with bigger brake effect needs to be loosened by required value.
