Procedure notes
Checking the brake fluid in your 2002 Audi A8 Quattro is easy and should be done once a month. On some Audis, the owners manual suggests pumping the brake pedal 25 times before looking at the fluid level, be sure to check your owners manual to see if this applies to your 2002 A8 Quattro. In addition to checking the brake fluid level, you want to look at the color of the brake fluid in your A8 Quattro - if it is dark in color or it has been more than 2 years since you have changed it, you should consider having it changed - this will help make the internal components (which are expensive) last much longer.If you need to add fluid to your A8 Quattro, it is important to check your owners manual for the correct type to add - it likely be either DOT 3, DOT 4 or DOT 5, also known as silicone brake fluid. Be sure to discard bottles of brake fluid that are over a year old - brake fluid sucks the moisture out of the air and the water vapor in the fluid can quickly rust out the brake lines in your A8 Quattro.
