Can stones in brake pads come out on their own?
2 Answers
Stones in brake pads can come out on their own. Brake pad lifespan: Under normal driving conditions, the front brake pads of a typical vehicle last between 30,000 to 50,000 kilometers, while the rear brake pads last between 120,000 to 150,000 kilometers. The exact replacement time depends on the specific wear condition. The manufacturer's recommended mileage may vary for different vehicle models. Brake pad replacement notes: When replacing brake pads, choose products from reputable manufacturers. Genuine brake pads from reputable manufacturers usually have clear packaging prints, including license numbers, specified friction coefficients, and execution standards. The packaging box should contain a certificate of compliance, production batch number, and production date. It is recommended to have new brake pads installed by professionals at a professional repair shop to avoid mistakes that could lead to potential safety hazards. Checking brake pad condition: When inspecting brake pads, it is also necessary to check the wear of the brake discs or drums to ensure sufficient contact area with the brake pads for improved braking force.
After years of driving, I've encountered brake noise several times, feeling like stones got stuck in the pads. Once while driving on a rural dirt road, the brakes screeched, and I guessed a pebble had lodged in the gap. After driving a bit more on a bumpy mountain road, the noise disappeared, likely because the stone fell out on its own. Theoretically, small stones might be flung out by the rotating brake disc, especially when loosened by bumps. But it depends on luck: the stone's size and how deeply it's stuck matter. Large stones wedged tightly won't come out easily and could grind the brake disc, damaging the car and risking lives. If you hear unusual noises, don't delay—try reversing a few dozen meters or gently braking a few times to test. If that doesn't work, get it repaired immediately; don't count on it resolving naturally. Safe driving comes first: avoid frequent gravel roads and regularly check brake health to prevent issues.
