How many kilometers should the brake discs of Hyundai Elantra be replaced?

[VonEthan]

Hyundai Elantra brake discs should be replaced every 60,000-70,000 kilometers or when worn to the limit value of 2mm. Below is relevant information about brake discs: 1. Structure: Vented-Disc refers to ventilated discs. Disc brake rotors are divided into solid discs (single discs) and ventilated discs (double discs). 2. Function: Brake discs are used for braking, with the braking force coming from the brake caliper. Generally, most brake calipers have a fixed inner section where the piston pump is located, while the outer section has a clamp-type structure. The inner brake pad is fixed on the piston pump, and the outer brake pad is fixed on the outer part of the caliper. The piston pushes the inner brake pad through the pressure from the brake fluid line, while simultaneously pulling the caliper through reaction force to move the outer brake pad inward. Both pads press against the brake disc, generating braking force through friction between the disc and the inner/outer pads. In this process, the piston is pushed by brake fluid, i.e., hydraulic oil. This is assisted by the engine.
