What Causes Car Brake Disc Noise?

[MarleyMarie]

The causes of car brake disc noise are: 1. Insufficient tension in the brake return spring; 2. The brake pad material is too hard; 3. The brake pads were installed too close to the brake disc. Types of brake discs include: 1. By structure, they can be divided into: solid brake discs and ventilated discs. 2. By material, they can be divided into: carbon fiber ceramic brake discs and metal brake discs. Methods to determine if a brake disc needs replacement are: 1. Brake pads and brake discs wear relatively; after replacing 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, you need to go to a repair shop or 4S store to check the brake disc.
