What could be the reasons for squeaking brake pads?
That annoying squeal when braking can send shivers down the spine of more than one driver. Is it a sign that the brake pads need replacing? Has something gone wrong, or is it just a one-off? There are several reasons why brake pads squeal, and not all of them require an immediate visit to the garage.
The squeaking noises made by brake pads, whilst sometimes irritating, are often a natural part of driving. When should you take your car to a garage to have them checked, and when can you wait a little longer and continue to enjoy a smooth, quiet ride?
Why do brake pads squeak?
The squeaking of the brake pads they usually occur during gentle braking – this is the classic vibration caused by the brake pad coming into contact with the disc. Most manufacturers of high-end brake pads use special linings on the backing plates to eliminate this irritating noise. Squeaking from the brake pads immediately after they’ve been replaced may therefore occur during the first few dozen kilometres, but if it persists beyond that, a visit to the garage is necessary.
A squeaking noise from the brake pads may be caused not only by wear but, above all, by overheating. In such cases, the pads are removed and resurfaced, but if the problem lies with the disc, it is advisable to replace it with a new one, as a warped disc no longer fulfils its function.
Brake pad squeaking and fitting
Although new brake pads tend to squeal, this annoying noise can also be a sign of incorrect installation. If the pad does not fit the caliper properly, it will start to vibrate, and these vibrations are what cause that distinctive sound.
In that case, we’ll have to go back to the garage and replace the brake pads with new ones. It’s worth bearing in mind, however, that due to incorrect fitting, replacement of brake pads will be carried out under the warranty.
Brake pads and rain
The squeaking of brake pads in wet weather should not be a cause for concern. Water and dirt that get between the brake pad and the disc cause an unwanted squeaking noise, which fades over time.
Why do brake pads squeak? To summarise, there are a few key points to note, two of which should not be a cause for concern:
- rain or a puddle – the squeaking of the brake pads gradually stops;
- new brake pads – the squeaking stops after driving a few dozen kilometres;
- overheated brake pads or disc – a visit to the garage is required;
- incorrect installation – replacement under warranty required.
To ensure you drive in complete safety, it is therefore worth listening carefully to the sounds your car makes – this will tell you whether the squeaking from the brake pads is just temporary or indicates that they need replacing.
