*11 Although surface layer materials of rubber hoses have excellent weathering resistance, heat resistance and resistance for
low temperature brittleness, they are likely to be damaged chemically by brake fluid, battery electrolyte, engine oil and
automatic transmission fluid and their service lives are to be very shortened. It is very important to keep the hoses free
from before mentioned fluids and to wipe out immediately when the hoses are adhered with the fluids.
Since resistances for heat or low temperature brittleness are gradually declining according to time accumulation of hot or
cold conditions for the hoses and their service lives are shortening accordingly, it is necessary to perform careful inspec-
tion frequently when the vehicle is used in hot weather areas, cold weather area and/or a driving condition in which many
steering operations are required in short time. Particularly continuous work of relief valve over 5 seconds causes to reduce
service lives of the hoses, the oil pump, the fluid, etc. due to over heat.
So, avoid to keep this kind of condition when servicing as well as driving.

FMVSS No. 116, fresh DOT3 or 4 brake fluid
CAUTION:

Avoid mixing brake fluid of different brands to pre-
vent the fluid performance from degrading.

When brake fluid is supplemented, be careful not to
allow any dust into the reservoir.

Use fresh DOT3 or 4 brake fluid when replacing or
refilling the fluid.
