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 inspection
frequently when the car is used in hot weather areas, cold weather areas and/or a driving condition in which many times
steerings 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 assembly, the fluid, etc. due to over heat.
So, avoid to keep this kind of condition when servicing as well as driving.
