Brake Fluid, Changing: Notes

WARNING: This page is about a different variant/trim than selected.

WARNING:

Brake fluid is poisonous.
Brake fluid must never come into contact with fluids containing mineral oils (oil, gas, cleaning solutions). Oils containing minerals damage seals and rubber grommets on brake systems.
Do not let brake fluid come into contact with paintwork.
Brake fluid is hygroscopic, meaning that it absorbs moisture from the surrounding air, and must therefore always be stored in air-tight containers.
Rinse off any leaking brake fluid with water.
Do not reuse used / extracted brake fluid!
Follow All Disposal Regulations.

NOTE:

Use Original VW/Audi Brake Fluid: Refer To The Appropriate Service Information
