WARNING
• Be sure to use the recommended brake
fluid.
• Use only one brand of recommended brake
fluid. Mixing of different brands or types of
fluid will change the properties of the fluid
possibly resulting in a lower fluid boiling
point and damaged brake components.
If you wish to change the brand of brake
fluid, replace all the existing fluid in the
brake system with the new brand fluid.
• Never allow engine oil, diesel fuel, gear oil,
automatic transmission fluid, or any other
mineral oil to mix with the brake fluid.
When mixed with the brake fluid even very
small in amounts, such oils will cause the
rubber parts of the brake system to swell,
and could cause brakes to become slug-
gish or to drag. Also, do not use containers
which have been used for mineral oil for
brake fluid.
• Because brake fluid is highly hygroscopic,
it should be kept in a dry place both during
refilling and storage. If brake fluid absorbs
moisture, the boiling point is lowered, a
condition which could result in vapor lock.
This is very dangerous.
• Brake fluid dissolves paint. If you spill the
fluid, wipe it clean or flush it off with water.
• If the brake fluid is used over long periods,
its boiling point drops significantly due to
the moisture it has absorbed, thereby
increasing the likelihood of dangerous
vapor lock. Therefore, be sure to change
brake fluid at least once every 12 months.
• When adding brake fluid, be careful not to
allow dirt and other foreign matter to enter
the reservoir tank. Any foreign matter
entering the reservoir tank could cause the
braking system to malfunction.
• If the brake fluid level drops abnormally,
brake fluid may be leaking from a pipe or
other component. Have the braking system
inspected by your nearest authorized
MITSUBISHI FUSO distributor or dealer.
