What Causes the Squeaking Noise in Brembo Brakes?
2 Answers
Brembo brakes producing squeaking noises may be caused by issues such as poor-quality brake pads, severely worn brake discs, or excessively worn brake pads. Brake Pad Quality: Substandard brake pads can cause abnormal noises during braking and may also damage the brake discs. It is necessary to replace them with genuine brake pads at an authorized 4S dealership. Severely Worn Brake Discs: When brake pads rub against severely worn brake discs, they can also produce abnormal noises. Prompt replacement of the brake discs is required. Excessively Worn Brake Pads: After prolonged use, brake pads naturally wear thin due to continuous friction. Excessively thin brake pads not only reduce braking effectiveness but also harden over time, leading to squeaking noises during braking. Timely replacement of the brake pads is the solution.
Seeing your question, I've encountered similar situations several times. Brembo brake squealing is usually not a major issue. The most common cause is small stones or metal shavings getting stuck in the brake pads, which creates a squeaking sound when braking. From my own car repair experience, newly installed Brembo brakes tend to squeak during the break-in period, typically for the first few hundred kilometers. Another example is during rainy or humid weather when brake discs accumulate dust or oil, causing uneven contact with the pads and resulting in squeaking. Check if your brake pads are severely worn - if the thickness is below 3mm, they should be replaced. Additionally, warped brake discs or loose mounting bolts can also cause noise. A simple solution is to clean the brake components first, or have a mechanic measure them with professional tools. If you frequently drive on gravel roads or at high speeds, dust accumulates faster and requires more attention to maintenance. Safety comes first - don't ignore the issue. Prolonged squealing increases wear and may affect braking distance, especially on wet surfaces. I recommend checking the braking system during every maintenance service to avoid bigger problems later.
