What Causes the Brake Pedal to Make Abnormal Noises?

[Legolas]

Abnormal noises from the brake pedal can be caused by new brakes during the break-in period or ABS activation. Below are the specific reasons: New brakes during the break-in period: New car break-in or newly replaced brake pads can cause abnormal noises from the brake disc. New cars or newly replaced brake pads have a break-in period during which some abnormal noises may occur. Typically, these noises will disappear after driving a few hundred kilometers. ABS activation: A normal signal of ABS system activation. During emergency braking, the brake pedal may produce a continuous sound similar to "thud-thud-thud," and sometimes there may be a pedal kickback sensation. This is caused by the ABS system activating.

I've found that when there's abnormal noise from the brake pedal, it's usually because the brake pads are worn out or there's debris stuck on the brake disc. As an experienced driver who's driven many cars, whenever I hear such squeaking sounds, I first check the braking system. For instance, if the pads are completely worn down and metal directly rubs against the disc, it will make noise; small stones or rust spots on the disc can also cause creaking sounds; lack of lubrication in the mechanical components connected to the pedal can lead to clunking noises; and air in the hydraulic system may produce a hissing sound when braking. These minor issues shouldn't be taken lightly, as brake failure at high speeds could be extremely dangerous. I recommend immediately taking the car to a reputable repair shop for inspection—they can quickly identify the cause using professional tools. To prevent problems before they occur, I always have technicians check the brakes during regular maintenance, especially after rainy or snowy days when rust is more likely to form. Abnormal noises are warning signals, so don't try to save money by delaying repairs.

Bro, my car's been making a clicking noise when braking lately. After checking around, it might be the pads wearing thin. Could also be dirt on the rotors – my buddy's car had a small stone stuck once. Or maybe the pedal needs lubricating, just gotta grease it up. If the booster pump's faulty, the brakes feel spongy and noisy too. Safety first, so I took it straight to the dealership. Remember, don't DIY repairs blindly – might make it worse. Brakes squeak more after rain, regular maintenance prevents trouble. I fix issues immediately to avoid roadside breakdowns.

Brake pedal noise is commonly caused by worn-out brake pads leading to metal friction sounds; debris on the disc; or lack of lubrication and rust on pedal components. Immediate inspection and part replacement are recommended. Safety should be prioritized.
