Can I change the brake fluid in an Audi A4 myself?
If you’ve never worked on your Audi before, don’t you dare start now without buying a Hanes or Chilton manual. They are about $20 and as far as your concerned, they are your Bible. Doing a brake job isn’t very difficult, and your Audi probably has all-wheel disc brakes, making it even easier, but that car may require special tools. Otherwise, you need a set of open-ended wrenches, a rag, a bucket, and someone to sit in the car and press the brake pedal while you loosen the ‘bleed’ nut on each wheel hub. You loosen. He presses the pedal down. (fluid shoots out) You tighten. He releases the pedal. Repeat until empty. And don’t get it on the paint or you will have a nice shiny-bare metal spot there next time you wash your car. Good luck homes.
