Brake ﬂuid

Introduction

Brake ﬂuid absorbs moisture from the air over the course of time. Too much water in the brake ﬂuid causes damage to the

brake system. Water lowers the boiling point of the brake ﬂuid. If the water content in the brake ﬂuid is too high, vapor lock ma

form in the brake system during heavy braking and full braking. Vapor lock reduces the braking efﬁciency, increases the

braking distance considerably, and can lead to a total failure of the brake system. Your own safety and the safety of others on

the road depends on your brake system functioning correctly at all times.

WARNING

Brake ﬂuid is poisonous. Contact with brake ﬂuid – in particular, if brake ﬂuid is swallowed – may result in serious injury or

death.

If you swallow brake ﬂuid, seek urgent medical help.

If you have health problems after working with brake ﬂuid, seek medical help.

Always store brake ﬂuid out of the reach of children and only within the sealed original container.

Never use empty food cans, bottles, or other containers to store brake ﬂuid, because someone could drink the

brake ﬂuid by mistake.

Avoid regular contact with brake ﬂuid to prevent damage to your skin.

Protect your skin, face, and particularly your eyes when working with brake ﬂuid.

Do not eat, drink, or smoke when working with brake ﬂuid.

Wash your skin with soap and water after working with brake ﬂuid.

395

NOTICE

Spilled or leaking brake ﬂuid will damage the vehicle's surfaces. The vehicle's paint, plastic parts, and tires may be

damaged.

Immediately wipe up any spilled or leaking brake ﬂuid that comes into contact with vehicle components.

Then rinse all vehicle parts with plenty of water.

Brake ﬂuid can pollute the environment. Collect spilled brake ﬂuid and dispose of it correctly.

Brake ﬂuid speciﬁcations
