How to Deal with a Stone Stuck in the Brake Disc?
2 Answers
The method to handle a stone stuck in the brake disc is: accelerate the car and then brake hard, then reverse and brake hard again, repeating this cycle several times to resolve the issue. The main components of a car's braking system include the vacuum booster pump, master brake cylinder, brake caliper, brake pads, and brake disc. Methods to determine if the brake disc needs replacement are: 1. Brake pads and brake discs wear relatively; after replacing the brake pads 2 to 3 times, pay attention to checking the brake disc; 2. If you hear a rustling sound when braking, check if the brake disc needs replacement; 3. If grooves or small pits appear on the brake disc, and the measured depth reaches about 1.5mm, it is necessary to go to a repair shop or 4S store to check the brake disc.
Yesterday while driving on a country road, my car's wheels suddenly made a sharp grinding noise, startling me into immediately releasing the accelerator and gently applying the brakes, slowly pulling over to a clear area to confirm safety. Getting out to check, I found a small stone stuck in the brake disc gap, probably kicked up from the gravel road. I tried slowly reversing or gently nudging the tire to loosen the stone but had no success, so I carefully used a screwdriver or a branch to pry at the stone's edge, being careful not to force it to avoid scratching the brake disc. After some effort, I finally removed it, started the car, and lightly applied the brakes to test—the noise was gone. However, if the stone had been embedded too deeply or mishandling caused wear, a trip to the repair shop would have been necessary. As a preventive measure, I've learned my lesson: avoiding prolonged driving over gravel areas and routinely checking tire treads to remove debris makes regular maintenance simple and worry-free, helping to prevent issues before they arise.
