Bendix advises on brake wear signs
Bendix provides advice on signs of brake pad wear and uneven pad wear ,and the importance of regular maintenance to the braking system.
A vehicle braking system plays an important role in keeping people safe on the road, and because of this wearing components in the friction area such as brake pads, calipers and rotors, all play an important role in stopping power.
The rate of wear depends on a wide range of variables such as the choice of brake pad, driving style, mileage travelled, the condition of the rotors and whether the brake calipers are working as they are designed.
There are a few signs to look for which indicate that the brake pads are reaching the end of their service life or are wearing unevenly. If the brake pads are wearing out they will not be working as effectively as they used to and another obvious indication is a squealing sound on braking as the wear sensors come in contact with the rotors.
Vibration is also a sign, and in more extreme cases a metallic scaping noise where the metal backing plate is coming in contact with the rotor.
In most cases it is possible to get a good view without having to take off the wheel to view the brake calipers to gauge the level of brake pads that is left. The latest brake wear indicator from Bendix makes this even simpler as there is an imprint on the side of each pad clearly marked “Replace” at the ultimate wear point. This is also a guide to uneven wear if one pad is worn down more than another.
Uneven wear is often a problem caused by disc thickness variation (DTV), where the rotors can wear down the brake pad due to the pad only being in contact with flat spots of the disc. Where this is identified the rotor should be replaced or machined and all components cleaned thoroughly with Bendix brake/parts cleaner and degreaser to clear away any dirt and provide an anti-rust coating.
In the case of uneven wear, components such as the guide pins in the calipers can seize, and these need to be eased out and lubricated with Bendix Ceramic High Performance Synthetic Lubricant or in extreme cases the calipers replaced.
Bendix recommends regular maintenance of the braking system in the interests of safer motoring.
