Volgograd drivers were reminded why creaking appears when braking
Screaming, whistling or squeaking when braking is a common situation faced by many car owners. Often, drivers perceive this sound as an annoying but harmless “acoustic defect”. In fact, extraneous noise is a signal that the brake system has deviations from normal operation. They should not be ignored: timely diagnosis will help to avoid more serious breakdowns and maintain safety on the road.
Main reasons
1. Wear sensor went off. The metal plate rubs against the disc when the pads are severely worn. Solution: check the thickness of the linings and, if necessary, replace the kit.
2. Poor-quality pads. Hard spots in cheap pads scratch the disc and cause a whistle. Solution: choose products of proven brands.
3. Souring of calipers guides. Due to dirt and loss of lubrication, the pad does not move away from the disk and constantly rubs. Solution: regularly clean the guides and apply a special high-temperature lubricant.
4.Problems with antiviral plates. If the plate is missing or deformed, vibrations and whistles occur. Solution: check its presence or apply the antiscrip composition on the back side of the shoe.
5. Disc wear or beat. Uneven fit of the pad due to grooves or deformation causes a hum and creak. Solution: measure the thickness and beat, with critical wear - replace the disk.
6. Weather factors. Condensation and microcorrosion on the discs give short-term creaking at the first braking. Usually the sound disappears after heating up the system - no special measures are required.
Significant rules
Often, car owners are faced with creaking immediately after replacing the pads. This may be due to the factory fascia (skis) at the edges of the new pad, which initially clings to the edge of the disc. To minimize discomfort, it is important to properly "wipe" new pads: the first 200-300 km should avoid emergency braking - the friction material should adapt to the micronervous disc. In parallel, it is necessary to serve the caliper: clean and lubricate the guides.
Conclusion
Brake screeching is not just an inconvenience, but an indicator that there is a problem in the system. If the sound does not disappear after warming up the brakes and several braking cycles, you should not postpone a visit to the service. Regular diagnosis, cleaning of calipers, timely replacement of high-quality pads and control of the condition of the discs will ensure the reliability of the brake system and eliminate extraneous sounds.
