Regular brake pad maintenance is a critical part of keeping your car running properly, and brake wear indicators can be an invaluable tool for letting you know when it's time for a brake pad replacement.
There are different types of wear indicators, acoustic and electronic. An electronic wear indicator comprises of a wear indicator in the brake pad, a circuit and a warning display on the dashboard. When the wear limit on the brake pad is reached, contact is made with the warning contact embedded in the brake pad. This completes the circuit, causing the warning device to light up, warning you that it's time to replace your brakes before they fail due to further wear and tear. Regular brake pad replacements are much less expensive than dealing with issues caused by brake failure or other related problems down the line, so be sure to pay attention and take prompt action! Either 2 or 4 warning contacts may be installed, depending on the design of the brake system.
Repair note:
The electrical wear contacts must always be replaced when replacing the brake pads!
When performing diagnostics or repairs, please observe the vehicle-specific information provided by the vehicle and brake manufacturers.
