What causes the clicking sound in the rear wheels when braking in a Volkswagen?
4 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.
There are quite a few reasons for a clunking noise in the rear wheels when braking. Technically speaking, uneven wear of brake discs can easily cause noise, and it's common for newly replaced pads to not be properly broken in or for discs to be warped. Sticking caliper pistons can lead to uneven braking force. Damaged rear wheel bearings are often the main culprit, with noticeable abnormal noises when driving and rotating. Suspension components like sway bar bushings can become fatigued and loose, causing bouncing under force. For routine checks, I usually jack up the car, spin the wheels to listen for noise sources, and test for looseness by shaking. Check if the ABS system is functioning properly and if the sensors are dirty. From a safety perspective, address any noise immediately—don't wait for a major failure. When replacing brake discs and pads, choose OEM parts to ensure compatibility and lubricate the sliding pins. Driving safety comes first; unusual noises are major warnings—don't delay repairs.
I'm no stranger to the clunking sound from the rear brakes of Volkswagen cars. The most common causes are worn-out brake pads or uneven rotor surfaces causing friction noise. Loose wheel bearings make the car wobble. Suspension linkage issues produce noise under stress. I recommend observing when the noise occurs during light or hard braking. Simple checks include measuring pad/rotor thickness and replacing pads; clean caliper dust. Replacing a bad bearing assembly is costly but life-saving. Address abnormal noises promptly - small issues become major hazards if neglected. Drive with peace of mind.
