What is the BMW brake disc replacement standard?

[DiJuliet]

According to BMW's officially recommended maintenance packages, the front and rear brake pads of BMW models should be replaced every 50,000 kilometers, while the brake discs should be replaced every 100,000 kilometers, which means replacing the brake discs every two brake pad changes. Here is some relevant information: 1. BMW brake disc thickness: Different BMW models are equipped with different brake discs, with thicknesses of 22mm, 24mm, 26mm, 30mm, etc. The usable thickness for general models is only 2.4mm. For M models or some models with drilled brake discs, the usable thickness is only 1.6mm. This means that for a 30mm-thick brake disc, 28.4mm is the limit, and it must be replaced at this point. 2. BMW brake disc usage: In terms of brands, BMW uses a variety of brake disc brands. Replacing brake discs, like replacing brake pads, requires a break-in period of several hundred kilometers. During this time, driving should be more cautious because the braking effect may not be optimal. Avoid resurfacing the discs lightly, as the usable thickness is already very thin—each resurfacing can reduce the lifespan by tens of thousands of kilometers.
