How to Remove Stones Stuck in Car Brake Discs?
2 Answers
Methods to remove stones stuck in brake discs mainly include: 1. Accelerate, then brake hard. 2. Reverse and brake hard again. 3. Repeat the cycle several times to resolve the issue. However, this method is not guaranteed to succeed. If unsuccessful, it is advisable to visit a repair shop or 4S store. Additional information: Stones stuck in tires mainly pose the following hazards: 1. Increased noise. If small stones are lodged in the tires, there will be significant tire noise while driving, which can be distracting to the driver and, in severe cases, affect the driver's judgment of road conditions. 2. Impaired tire performance. The grooves on tires are designed for water drainage. When filled with small stones, the drainage effect is weakened. Driving on wet and slippery roads in rainy conditions may lead to skidding, compromising vehicle safety. 3. Risk of air leakage or tire blowout. If hard and sharp stones or hard objects like patches are stuck in the tire treads, they may puncture the outer rubber layer of the tire during high-speed driving, potentially causing a blowout.
Last time I went on a road trip, I also encountered a squealing sound from the brakes—it was just a pebble stuck in them. The easiest solution is to find a safe stretch of road, speed up to around 50, and then slam on the brakes a couple of times to let it shake loose. Just remember to check the distance of the car behind you! If the noise persists, you’ll have to take action: first, park the car safely and turn off the engine, then use needle-nose pliers or a thin screwdriver (with gloves on) to carefully dig it out from the wheel hub gap. If you still can’t reach it, turn the steering wheel all the way to rotate the tire position. A word of caution—never use a hammer to hit the brake disc; it’s highly precise, and if it gets deformed, repairs will cost even more. When parking, try to avoid gravel roads, as muddy roads after rain are especially prone to trapping pebbles.
