How do I fix the brakes on my Audi 80?

My Audi 80 seems to have brake issues, and I'm not sure how to fix them. What steps should I take to address this problem?

First, check the brake pads to see if they need to be replaced. If they do, make sure to also replace the brake rotors at the same time.

If the brake pads and rotors are in good condition, the issue may be with the brake lines. Inspect the lines for any leaks or cracks and replace as needed.

If the brakes still seem to be malfunctioning, it could be an issue with the brake master cylinder. This may require professional assistance to fix.
