Squealing brakes on your Mercedes Benz can be annoying to the driver, passengers and passers-by. This could be an indicator that your Mercedes Benz’ brakes need attention. Hot or cold weather and high humidity often make brake-squeal that may stop when the lining reaches regular operating temperatures. Dust buildup in and around the brake caliper, pads, and guides on the brakes may also cause squealing. Modern technology has replaced the old “squeal strip“ method with an electronic sensor that turns on a message on the dash board that indicates that your brake system needs attention. Typically when this message appears your brake pads, rotors and sensors need replacement.
Whether you need front or rear brakes, it is important to replace all three components on your Mercedes Benz:
- Brake pads
- Brake rotors
- Brake sensors
If you can feel the grooves with your fingernail, the rotor is probably too rough and it should be replaced. Rotor replacement is also required if the rotors are warped or cracked.
No rotor should be re-used unless you have measured its thickness with a micrometer and it’s proven to be over the manufacture minimum thickness spec. A rotor must be replaced if it’s worn down to minimum specifications or the discard thickness. These measurements are often stamped directly into the rotor itself. The specification allows for a certain amount of wear to occur before the rotor reaches the end of its service life. Rotors should be replaced in pairs to keep the wear on both sides even. Brake sensors are a one-time use item, as well, and need to be replaced with the other parts of the Mercedes Benz braking system.
