Do Brake Discs Need to Be Replaced Frequently?

[DelilahLynn]

Brake discs generally need to be replaced when the vehicle has traveled 80,000 to 100,000 kilometers. Here are the criteria for determining when to replace brake discs: 1. Observe the brake disc warning light: Normally, the brake disc indicator light is off. When there is a fault or excessive wear in the brake disc, the light turns on and goes off after repair. When the warning light is on, the brake disc has worn to its limit, braking performance has decreased, significantly affecting driving safety. Therefore, car owners should regularly check the wear condition of the brake discs to see if they are still usable, rather than relying solely on the warning light. 2. Check the thickness of the brake disc: Most brake disc products have wear indicators, which are three small pits distributed on the disc surface. Using a vernier caliper, the depth of these small pits is measured to be 1.5mm. This means that when the total wear depth on both sides of the brake disc reaches 3mm, the car owner should promptly replace the brake disc.
