OE 1404230412 — Brake Disc for Mercedes-Benz

Position depends on the platform. On most Mercedes-Benz applications the brake disc sits on the brake system assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the brake disc should be inspected, and reference 1404230412 replaced if it measures outside specification.

Aftermarket brake disc comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

Three checks: the code printed on your old part must read 1404230412; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.
