Almost every Audi for the past 20 years has been equipped with electronic brake pad wear sensors. Most of them mount the brake pad with a clip, but some are molded into the brake pad. These sensors change their electrical resistance as the loop of wire is worn down and eventually breaks as the brake pads wear down.

There are no shortcuts to performing a noise-free brake job. It is a difficult job that requires combining the correct parts, knowledge and preparation to make sure that the brakes do not make a noise for more than 20,000 miles or more.
The process by which your ears work is amazing. Moving air hits a diaphragm in your ear and tiny bones activate nerves that transmit signals to the brain. How the air, diaphragm and nerves interact can mean the difference between conversation or annoying brake noise.
Under extreme braking conditions, some lubricants can’t take the heat and melt off, evaporate, oxidize or burn. That’s why ordinary, general-purpose chassis grease should never be used for lubricating brake components. It simply won’t hold up.
Replacing rotors on every brake job is not a cost-effective or efficient way to perform brake service. You may save 10 to 15 minutes by not having to use a dial indicator and a micrometer, but your risk of a comeback can dramatically increase.
Some vehicles may experience a squeaking or grinding noise originating from the front or rear disc brakes when the brake is applied. The concern may be related to the brake pads sticking and not moving freely in the slides due to lack of lubrication and/or corrosion.
Customers may complain of a high-pitch noise from the front brakes during a low-speed light brake application.
