This is an extreme example of what can happen when you ignore brake noises, but it doesn’t take a rotor worn all the way down to the vanes to make annoying noises…

We’d hope that, as an automotive enthusiast, you pay closer attention to the condition of your vehicle than most drivers. You don’t ignore the subtle (and unsubtle) signs of brake trouble on the horizon, like noise and unusual pedal feedback when you apply the binders. But what about those elusive squeaks, groans, and hisses that happen when the brakes aren’t being used? Much more vexing to troubleshoot, these problems often have a straightforward cause, and our friends at DBA USA have come up with some advice to hunt down brake gremlins.

DBA USA offers replacement high performance brake rotors for a wide range of applications, but they’ve also taken the time to pen a few very interesting technical articles that cover topics ranging from how thermo-graphic paint works to the tradeoffs involved in slotted and drilled rotors. This particular article on brake noise is one of several that are applicable no matter whether you are running stock or aftermarket brakes.

They identify five primary sources of noise while the brakes aren’t being applied: Debris, surface contamination, damaged components, caliper or pad issues, and parking brake problems. Each is addressed in turn, with things to look for and potential solutions offered. Diagnosing these minor issues before they have a chance to become major ones is key – after all, there’s no safety system on your vehicle more important than the brakes, and DBA USA urge readers to let the pros handle any major repair beyond your own comfort level.
