What are the effects of resurfacing brake discs?
4 Answers
Resurfacing brake discs can cause deformation of the brake discs. If the brake discs are severely worn and cannot be resurfaced, they need to be replaced. Introduction to brake discs: A brake disc is a circular disc that rotates when the vehicle is moving. The brake caliper clamps the brake disc to generate braking force - when you press the brake pedal, it's this clamping action that slows down or stops the vehicle. Effects of aging brake discs: If the brake discs are severely worn and cannot be resurfaced, they need to be replaced. Steering wheel vibration is mostly caused by deformed brake discs or aged/loosened suspension systems.
I still vividly remember the time when my car's brake discs became too smooth. While driving downhill, I felt the brakes weren't as effective as usual, and the car slid much farther than normal, almost resulting in a rear-end collision. The mechanic explained that the disc surface had become too smooth, significantly reducing friction, likely due to uneven wear of the brake pads over time or frequent hard braking. The consequences weren't just longer braking distances but also increased safety risks, especially in rainy or snowy conditions where skidding becomes more likely. I spent 500 yuan to resurface the discs, but the effect only lasted six months before the problem recurred. Later, I learned to inspect the brake system every six months, use smooth braking more often, and avoid frequent hard stops. This issue not only affects driving experience but also wastes money and time, making regular maintenance a key preventive measure.
I worked in an auto repair shop for two years and often encountered customers complaining about poor braking performance. In many cases, it was caused by overly smooth brake discs. A glossy surface reduces friction, leading to diminished braking effectiveness and failure to stop. This is primarily due to worn brake pads or excessive road dust accumulation. The impact isn't just longer stopping distances—it can also cause vibrations, unstable steering, especially dangerous at high speeds. For repairs, the disc surface can be resurfaced for about 300-600 yuan, or replacing the disc entirely is more expensive. I recommend having technicians check disc wear during every maintenance service, and using high-quality brake pads can delay this issue. Simple prevention: clean wheel hubs to reduce debris and avoid sudden braking in daily driving.
A smooth brake disc surface can lead to serious consequences. As a long-haul truck driver, I emphasize that this directly threatens driving safety. The insufficient friction of a smooth disc results in delayed brake response, increasing collision risks. Especially when fully loaded, the braking distance extends by over 10%. Pay attention to abnormal symptoms like squeaking or shaking brakes, as they are warning signs. It is recommended to seek repair as soon as possible when encountering these issues. Resurfacing the disc can provide a temporary solution, but replacement is necessary in severe cases. Adopting reasonable driving habits, such as braking in advance and keeping the disc surface clean, can effectively prevent this. Long-term neglect can also damage other components of the braking system.
