Have used Foxwell NT510 hand-held scanner to retract BMW E90 E-brake pads. It cannot be more easier, i think. Much more convenient compared with K+DCAN cable. No need a laptop for running INPA software.
Here is what i did.
There is much more other stuff added with NT510 scanner. But this is the most important. I was surprised there is an ignition coil re-calibration (LVS) function when change coils. Interesting! I applied NT510 scanner when i saw it as i was running the new BMW OEM Eldor coils
