Changing Pads with SBC Braking & Disabling System on E55
However, my question is - if both car batteries are so dead that the key will not even turn in ignition - can the caliper safely be opened with no worries ?
Does the SBC system also apply to the rear calipers & pads, or only fronts ??
Lastly, are rear brake pads swappable between E55's and E63's ?
Thank you
