My understanding is two fold - regeneration capture on the rear brake and more level braking rather than the front dipping

There’s no regeneration capture argument for this thread, the OP’s car is T4 AWD.

Oh OK :shock: - wonder if regeneration is on B4's as their seems to be more wiring around that area ;)

The 'braking regeneration' is misleading. It doesn't in any way use the brakes, but increases the alternator charging which has the effect of more engine retardation or 'braking'. It might I suppose lighten the physical braking on the front wheels to compensate for the engine braking on the front (even on the AWD I would imagine under braking it wouldn't be engaging the rear drive)

This applies equally to the old 12v stop start, and the new B series 48v

Don't forget the rear brakes are part of the various stability control systems.

There is one sure fact, when it comes to the rear brakes on an XC40 - it eats through brake-pads like tiny-Tim on a Christmas ham.

Excessive brake wear is not exclusive to XC40. My last car was a mk1 XC60 and needed new rear disks after 35k miles of gentle driving. Front brakes were fine. No fancy auto hand brake on that model.
