Be careful to degrease your discs! At no point is this indicated in the tutorial! You will be heading straight for an accident if you don't do it with brake cleaner.

In addition, once the disc is removed and the hub is cleaned, I recommend applying copper grease all around, this will prevent rust for future disassemblies ;)

Too bad there aren't the recommended tightening torques.

Good morning,

Thanks for this tutorial.

I have CC-ID code 71 on my X1's dashboard.

how to know if you need to change pads, discs and pad or pads, discs and wear sensor

Thanks in advance

Bjr.

All that's missing is the precise way to remove the recalcitrant cover and the case of the pad wear sensor. And maybe also the tightening torque of the wheel screws, apart from that, perfect.
