What causes the clicking sound in the rear wheels when braking in a Volkswagen?
2 Answers
Volkswagen rear wheels making a clicking sound when braking could be due to abnormal noise from the clutch, drive shaft, differential, or even the tires. If the noise only occurs during braking, it is necessary to check whether there are any foreign objects stuck between the brake pads and brake discs. If the brake system is functioning properly, the tires and suspension system should be inspected. During braking, the vehicle's center of gravity shifts forward, increasing pressure on the front axle. If the noise occurs every time you brake, there may be an issue with the front axle. In daily use, if the car produces abnormal noises, it is important to promptly visit a 4S shop for inspection and repair. After replacing the brake pads, clicking sounds may occur during each brake application as the new brake pads have not yet adapted to the brake discs.
I've been driving a Volkswagen for several years and have encountered the issue of a clunking sound from the rear wheels after braking several times. The main causes are usually uneven brake rotors or excessive wear on the brake pads. For example, if the rotor surface has grooves or scratches, uneven friction between the pads and rotor during braking can produce noise. Loose calipers or rusted guide pins can also prevent the pads from retracting properly, leading to knocking sounds. Another potential issue is a damaged wheel bearing, which can cause a wobbling sensation when rotating and worsen the clunking noise. Aging suspension components, such as cracked control arm bushings or leaking shock absorbers, can also produce creaking sounds under stress. I recommend first checking the thickness of the brake pads—replace them if they're below 3 mm. Test the wheel hub for any looseness and lubricate caliper components during regular maintenance. Don’t overlook these details, as safe driving depends on promptly addressing the sources of unusual noises.
