The wear resistance of Car Brake Discs is affected by a variety of factors.
The material is a key factor. Brake discs made of different materials have significant variations in wear resistance. For example, high-carbon alloy brake discs, with their high carbon content and greater hardness, are more wear-resistant than ordinary cast iron discs, resisting wear during frequent braking and extending their service life.
Driving habits also play a role. Frequent, sudden braking exposes the brake discs to intense friction and high temperatures, accelerating surface wear. However, steady driving, anticipating road conditions, and minimizing sudden braking can reduce the rate of brake disc wear.
The working condition of the brake system is equally important. Poor-quality brake pads containing hard particles can act like sandpaper to abrade the disc during braking. A poorly returned caliper, resulting in constant, minor friction between the pad and disc, can also cause abnormal wear.
The operating environment also plays a role. Long-term driving in dusty, humid conditions can embed dust into the disc surface, and humidity can easily cause rust, all of which can weaken its wear resistance.
