On tractors with FENOX main brake cylinders after making adjustments, also fill the drive
hydraulic system with brake fluid and bleed the hydraulic system. Due to construction spe-
cific character before filling and bleeding the hydraulic system of service brakes control
please disconnect pipelines 1 and 4 (figure 5.4.26) from outlet holes of main brake cylin-
ders 7 and 8 by unscrewing bolts 2, 5. Fill tanks 3 and 6 of the main brake cylinders with
brake fluid up to the mark ‘’MAX” on tanks housings. After brake fluid appears from outlet
holes of the main brake cylinders connect pipelines 1 and 4 to outlet holes of main brake
cylinders 7,8 and start bleeding according to the abovementioned method for tractors with
main brake cylinders of the company CARLISLE.
ATTENTION: IF AFTER DISCONNECTION OF PIPELINES FROM OUTLET HOLES OF
MAIN BRAKE CYLINDERS WITH TANKS FILLED NO BRAKE FLUID APPEARS FROM
OUTLET HOLES OF MAIN BRAKE CYLINDERS AFTER MORE THAN FOUR MINUTES,
IT INDICATES, THAT VALVE BETWEEN TANK AND CYLINDER OPERATING CAVITY
IS CLOGGED. IN THIS CASE THE BLEEDING OF HYDRAULIC SYSTEM IS NOT POS-
SIBLE. TO ELIMINATE THE DEFECT PLEASE CONTACT YOUR DEALER.

5. Check the value of the unlocked pedals full travel separately applying force of (300±30)
N which shall be within 100 to 120mm. In case the value of the pedal full travel exceeds
the specified limits, it is required to make adjustments doing the following operations:
- uncrew counter nuts of rod-bolts 6 and 10 (figure 5.4.25) by several revolutions;
- screw in and screw out adjusting rod-bolts 6 and 10 of the right and left service brakes;
- lock the rod- bolts.
6. Check the efficiency of service brakes operability during tractor movement along dry
road with hard surface with the clutch off. When the interlocked brake pedals are de-
pressed with the force of 590 to 600 N, the length of braking path shall not exceed 6,4m
with the tractor travel speed of 20 km/h. Unevenness of tractor movement in the process of
braking shall not exceed 0,5m. If necessary, adjust the simultaneity of braking start by
means of one of adjustable bolt-links 6 or 10.
