10.4.3.4 Brake fluid
Observe when handling brake fluid:
• Brake fluid is caustic. It should not touch the varnish. If necessary immediately
wipe off and wash down with much water.
• Brake fluid is hygroscopic, that means it absorbs humidity from the air. Therefore
only store brake fluid in closed containers.
• Never reuse brake fluid that had been used in the brake system before.
Also when venting the brake system only use new brake liquid.
• The high requirements on the brake liquid are subject to the standard SAE J 1703
or to the American safety precaution law DOT 3 or DOT 4.
Only use brake liquids according to DOT 4 .
• Brake liquid must never ever tough mineral oil. Even a little trace of mineral oil
would waste the brake liquid and would cause a failure of the brake system. Plugs
and sleeves of the brake system are damaged when they get into tough with
mineral oil agents. Do not use mineral oil containing cloths for cleaning.
• Exchange the brake liquid very 2 years, if possible after the cold season.
Warning!
Never ever reuse drained brake fluid.
By no means pour away drained brake liquid or dispose it with the household
waste. Collect it separated from used oil and dispose it via authorised waste
disposal companies.
