How can I diagnose a faulty brake system in my Audi 80?

I am experiencing irregular braking and want to know how to properly diagnose and address the issue in my Audi 80. Can anyone provide some steps or guidance?

First, you should check your brake fluid levels and see if they are low. If so, top them off and see if this resolves the issue. Additionally, check your brake pads and rotors for wear and tear and replace them if necessary.

Another possibility is a faulty brake caliper. You can determine this by manually applying pressure to each caliper and checking for excessive resistance or lack of movement. If this is the case, replace the caliper accordingly.

It could also be an issue with the brake master cylinder. Check for any leaks or cracks and replace if necessary. Don't forget to bleed the brakes after replacing the master cylinder.
