Quiet rumbling when braking

Noises when braking

What noises mean when braking

In general, the earlier you take action, the sooner you will avoid costly consequential damage. In any case, it is advisable to go to a workshop to clarify the noise. You don't need to panic right away - there are clues to tell a dangerous sound from an insignificant one.

  • If you hear a grinding noise, this can be an indication that the brake pads are worn out. The best thing to do is to find a parking space immediately and check the brake fluid.
  • You can hear these grinding noises because the brackets of the brake pads rub against the brake discs, causing a loss of fluid. That is what is dangerous about worn surfaces.
  • If strange noises occur when braking, mainly in wet conditions, the brake shoes or brake discs may be worn.
  • A brake caliper can also come loose and draw attention to itself with a click. If there is no need to replace it, it is often sufficient to retighten the screws.

In any case, it is necessary to have defects checked immediately in a workshop and rectified immediately. If you do not visit the workshop, the brake disc can turn blue due to overheating, which is called "glazing". Every driver can imagine the consequences of a reduced braking effect.

Not all strange noises on the car are problematic

Not every source of noise coming from the brake system inevitably indicates defects. Even when brake pads are wet, they make noises. However, the problem is solved if you drive a kilometer and use the brake pedal vigorously in between. If you have recently replaced the pads, there may also be screeching discrepancies.

  • Try to avoid emergency braking for the first time. Sometimes it can take a few days until new brake pads are really "ready to brake". If installed correctly, the noise is harmless to you.
  • If you drive an older vehicle, the cause of a supposed brake noise may be from the brake pedal. In this case, too, it is advisable to go to a workshop to find out the reason.
  • After a long period of standstill, there is rust film on the brake system, which can be braked away. Often the ABS is also affected and lights up permanently.
  • Usually the noise disappears after a few kilometers and the lamp goes out. If it stays on, if there is resistance on the brake pedal and a short clicking noise, the brake cylinder is probably defective. Now quickly to the workshop.

Your car makes strange noises when braking and you want to remedy the source of the noise yourself quickly? This is only recommended if you are an accomplished auto mechanic. A squeaking or dragging brake belongs in the hands of a professional! Remember: Your safety and that of other road users come first.
