What are the effects of brake pad rust?
2 Answers
The effects of brake pad rust include: 1. If the rust is slight and does not corrode the brake disc, it has no impact on the performance of the braking system; 2. If the rust is severe, it may cause abnormal wear on the brake disc, leading to scratches and grooves, which can affect braking performance. Precautions for using brake pads: 1. Before driving, check if the handbrake is released; 2. Clean any foreign objects on the brake pads regularly. Automobile brake pads are generally composed of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, and the coating process is monitored with a furnace temperature tracker to ensure the temperature distribution during coating meets quality standards. Brake pads can be categorized into: disc brake pads, drum brake shoes, and truck brake linings.
Last time I washed my car, I noticed the brake discs were covered in rust spots, which gave me quite a scare. The mechanic explained that this is most likely to happen with short-distance driving, especially after parking outdoors in rainy weather. A few light presses on the brakes will wear off the rust powder, and it won't affect braking performance. However, the mechanic warned that if there's a sharp screeching noise or steering wheel vibration when braking after rusting, it indicates deep rust damage to the brake discs, requiring professional resurfacing. Prolonged neglect could increase braking distance by 2-3 meters, making downhill sections particularly dangerous. For the past six months, I've been avoiding parking in damp areas and taking more highway drives on weekends to prevent rust.
