How to troubleshoot brake problems in an Audi 80?

I've noticed decreased braking performance in my Audi 80 and I'm not sure what the issue could be. What should I look out for and how can I troubleshoot the problem?

First, check the brake pads and rotors for wear and tear. They may need to be replaced if they're too worn down. Also, check the brake fluid level and make sure it's topped up. Next, inspect the brake lines and check for any leaks or damage. If everything checks out, it could be an issue with the brake calipers or master cylinder. I recommend taking your Audi to a trusted mechanic for a thorough inspection.

Before taking your Audi to a mechanic, you can try bleeding the brakes yourself. This can help remove any air bubbles that may be affecting the brake performance. Also, make sure the tires are properly inflated, as low tire pressure can affect braking. If these steps don't solve the problem, it's best to have a professional take a look at it.

I've had similar issues with my Audi 80 in the past and it turned out to be a problem with the ABS module. If you notice the ABS light on your dashboard is illuminated, that could be the cause of the poor brake performance. In that case, the module will need to be replaced. It's best to have a mechanic diagnose and replace the module.
