Why Do Brakes Make Noise?
2 Answers
Brake noise when pressing the pedal may be caused by the following reasons: 1. Issues with engine speed. 2. Loose attachments on the brake pads. 3. Malfunctions in the brake caliper, such as worn sliding pins or detached spring plates. 4. Excessive wear on the brake discs or brake pads. Both brake discs and pads are high-wear components that undergo friction with every brake application, leading to natural wear over time. When excessively worn, abnormal noises may occur, necessitating regular inspection and replacement. Typically, brake pads should be replaced every 60,000-80,000 kilometers, and brake discs every 100,000-120,000 kilometers.
There are quite a few reasons why brakes make noise. I've been driving for seven or eight years and often encounter this issue, especially in winter or after rain—every time I press the brakes, they squeak. The main cause could be debris stuck in the brake pads, like tiny stones or dust, which creates noise when rubbing. Another reason is the material of the brake pads themselves—if they're too hard, they tend to squeal, or if they've worn unevenly due to aging, they may need replacement. Last time I went for car maintenance, the mechanic mentioned that if there's too much moisture and rust forms on the brake discs, initial braking might produce noise, but it usually goes away after a few presses as the rust wears off. Remember, don't worry too much, but if the noise persists or is sharp and piercing, it might indicate severe brake pad wear, so it's best to get it checked—safety first, after all, since longer braking distances can be dangerous. Regularly cleaning dirt around the tires can also help reduce such issues.
