Tech Tip: Ford/Lincoln Rear Brake Drag Or Rear Brake Noise
Some 2009-2010 Flex, MKS and 2010 Taurus and MKT may exhibit rear brake drag and/or off-brake cyclic noise. The noise may be caused by pad to piston misalignment or corrosion on the brake caliper bracket. Follow the Service Procedure steps to correct the condition.
Diagnosing Your Customers’ Brake Noise Complaints
Squeaking can be the most challenging and is often evident after the brakes have been serviced. The best way to deal with brake squeal is to prevent it in the first place. While we’re all familiar with brake service, it never hurts to review good practices.
Solving Brake Noise Complaints
Most brake complaints will be squeak-related, with the common metal-on-metal grinding taking a close second. Both of these noises relate to the pad. The grinding noise is almost always the result of worn pads and the backing plate contacting the rotor, and we all know how to deal with that. To a lesser extent, you’ll also get some knocking complaints.
Tech Tip: Brake Noise or Pulsation
Beginning with some models, GM has introduced a new brake rotor technology called Ferritic Nitro-Carburizing (FNC). Simply put, it is an additional step in the manufacturing process of the brake rotor that creates a hardened outer layer on the surface of the rotor.
Tech Tip: Mazda MPV Brake Noise Keeps ‘Popping’ Up
Mazda MPV owners may complain about rear brake noise. While applying the brakes under normal stopping conditions, usually at low speeds, a metallic popping, clicking or squealing sound can be heard coming from the rear brakes. This may be caused by uneven contact between the brake lining and the brake drum.
Tech Tip: Uncovering Source of Brake Noise Complaints
What does your shop do when a brake complaint due to noise enters the service bays? Is it a mark of shame for the technician that hurts their productivity for the rest of the day by randomly applying lubes, pastes and sprays to the brake system in hopes that the problem is at least temporarily solved? Brake systems are complex and require an ….

Tech Tip: Brake Noise/Creak During Slow Speed Braking
Some customers may comment on a creak-type noise occurring when applying the brakes. It is usually heard only during slow speed brake maneuvers. If this condition exists, it should be able to be duplicated when the vehicle is not moving by depressing the brake and listening for the noise from the wheel-well/caliper area.
Brake Lubricants: Reduce Noise And Optimize Performance
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.
