BRAKES
Fig. 5.7. Adding Fluid Into Master Brake Cylinder
1. Master Brake Cylinder 2. Access Door
If the sight gauge is only partially filled or shows no fluid, lift the inspection door (2, Fig. 5.7) in the
floorboard just to the left of the operator’s seat. Clean filter cap (2) before removing it to prevent
foreign matter from falling into the master cylinder housing. Undo the securing fasteners and
remove the filter cap (1, Fig. 5.7) and add fluid. The correct fluid level is 6 [mm] from the top edge of
the master cylinder. Reinstall the filler cap.
5.7.3. CHANGING THE BRAKE FLUID
Perform the following steps when changing brake fluid:
1. Disassemble brake system warning light switch (3) from differential valve (2, Fig. 6.7)
2. Disconnect brake lines (1 and 2) supplying both LH and RH brakes of both axles from tee
connector (3, Fig. 5.8). Connect the lines and drain the fluid from the drive axle to a container.
