What Causes the Clicking Noise When Braking?

[DiLaila]

The reasons for the clicking noise when braking are: 1. Normal ABS activation, where the vehicle is in a critical lock-up rolling state, causing noise—this is normal; 2. Excessive wear of the brake disc and brake pads; 3. Faulty installation of the brake pads; 4. Brake system malfunction or loose components in the chassis. Solutions for the clicking noise when braking include: 1. Reinstalling the brake pads; 2. Replacing the brake disc; 3. Checking for loose attachments on the brake pads; 4. Inspecting for brake drag or poor caliper retraction; 5. Normal ABS activation—simply apply full force when braking.

I've been driving for ten years and have encountered this kind of brake clunking noise several times. During the last maintenance, it was found that the rear brake pads were almost worn out, and the metal retaining clip was directly scraping against the brake disc. Another time, a friend's car had aged and cracked lower arm bushings, causing a clunking sound when going over speed bumps. Actually, the most concerning with such noises is if the suspension system's ball joints are loose or the shock absorber mounting bolts are loose, especially when encountering bumps at high speeds, which is particularly dangerous. It's advisable not to delay and to quickly go to a repair shop to have the car lifted for inspection. The technician will use a pry bar to shake the components near the tires one by one, making it easy to locate any loose parts. If it's a small part that's broken, it won't cost much to fix. Don't wait until the day the wheel starts to veer off while driving to regret it.

I just dealt with this issue last month when there was always a dull thud from the rear during braking. The inspection revealed two problems: the guide pins of the rear brake calipers lacked grease and got stuck, preventing the brake pads from fully retracting; additionally, there was play in the ball joint of the stabilizer bar's small link. The mechanic said that aging chassis bushings are the most common cause, as cracked rubber leads to direct metal-to-metal contact and noise. It's recommended to focus on checking the rear suspension's stabilizer bar bushings and control arm bushings, as these rubber components tend to harden after five or six years. If it happens after rainy weather, it's likely due to rusted or loose exhaust pipe hangers.

Just helped my dad check the same issue on his car, sharing some troubleshooting experience. First, crawl under the car to check if the exhaust pipe hanger is broken - this can be done yourself. Then, press firmly on the trunk to see if the shock absorber is leaking oil or making abnormal noises. Finally, have a friend listen outside during a test drive to determine if the sound is coming from the left rear or right rear. Common fault points: 1. Worn rear wheel bearings will make noise that changes with speed; 2. Unsecured spare tire in the trunk; 3. Loose fuel tank straps. If brake pads were recently replaced, the anti-rattle clips might not be properly installed.

Last year during a long-distance drive, I encountered this issue where the car made a clunking sound especially when braking downhill. It turned out to be caused by loose fixing bolts on the rear axle torsion beam. Never overlook such chassis abnormal noises. It could be a minor issue like an unsecured spare tire, but it might also be a precursor to something serious like a fractured brake caliper bracket. I recommend paying attention to the pattern of the noise: if it only occurs when reversing, it might be a caliper installation issue; noises on bumpy roads are often due to damaged suspension bushings; for abnormal sounds during straight-line braking, check the braking system components first.

My car developed abnormal noises at 60,000 kilometers. The inspection revealed three issues: the rear brake pad wear indicator was deformed and rubbing against the brake disc, the stabilizer bar bushings were completely shattered, and the shock absorber top mounts were deformed. The repair shop said such compound failures are quite common, all caused by aging rubber components. They recommended checking the condition of chassis bushings every two years, especially for vehicles frequently driven on rough roads. If abnormal noises occur after replacing brake pads, it might be due to insufficient application of anti-squeal paste, requiring reinstallation. Additionally, vehicles with modified suspensions should pay special attention to the condition of the strut mount bearings.
