subject: Brake Repair - Listening For Different Sounds [print this page] Cars today are usually equipped with an anti-lock system (ABS). This system's purpose is to keep the wheels from locking in a sudden stop, and the installation of these systems has taken the pressure off the driver to remember to stop differently in an emergency. Before, pumping the pedal was suggested in critical situations, but the urgency of a moment was cause for a driver to forget the rules of the emergency, and then came the standard installation of ABS. The system automatically engages when the car senses a wheel-locking situation. The initiation of the system makes a noise. If a driver is familiar with this noise, it can keep him/her from taking the vehicle in for a diagnostic without need. It seems a little bit of a stretch, but it is true: vehicles are often taken in for repair due to the initial noise the ABS makes when engaged.
Another addition that can cause a non-urgent noise is the installation of high performance carbon-metallic pads. Often those who tinker in refurbishing lean toward this upgrade, and to the sheer annoyance of the person who has shelled out the bucks or the time for the high dollar extra, high performance carbon-metallic pads makes noise. The only way to nip the noise is to install a stereo system that will outdo it, sound proof the cab of your vehicle, or change back to regular pads. Bummer!
Of course certain driving conditions can attribute to noise. Steep grades and frequent downhill driving which often result in riding the pedal can cause some screeching, and though it is suggested that if this type of route is par for your driving conditions that you have your brakes checked often and thoroughly, it is probably just the environment of the aforementioned driving situation that is attributing to the noise. Slowing down by alleviating the accelerator rather than applying the pedal can help with both the noise and the wear and tear on the vehicle, but keep safety in mind. Riding the brake is not always appreciated, but in actual stop and go situations, your brake lights are there for a reason, and that reason is for your safety and the safety of others.
There are a number of things that can cause your braking system to make various noises, but it can be extremely helpful for the pocket book to know these situations that do not spell danger solicite immediate repair. Any question as to whether a particular noise is a sign of peril should be alleviated by taking the vehicle in for a professional opinion.
