However, still considering about doing the rears on daughter’s 2010 XC70 with electric parking brake (EPB) as I’ve no previous experience of these. Looks soooo easy on YouTube.

9v pp9 battery, 2 fly leads with normal spade connectors crimped to one end. Remove the connector fit the fly leads to the motor terminals , bear off 6mm at the end of the fly leads and hold them to the pp9 battery, if motor runs the wrong way reverse the battery conections. Wind the motor back fully and then bar the piston back into the caliper. Dismantle caliper to change pads, change pads, reconect the connector, turn ignition on and engage EPB.

Some will tell you to open the bleed nipple when pushing the piston back, I have never found the need and certainly never flipped the master cylinder rubbers. Thinking on this, if it were a possibility then why does the rubber not flip when the brake peddle is pressed. That it does not indicates to me it will not. Just make sure there is room in the fluid resevour for the displaced fluid.

The official manual method is to remove the motors, they are held by 2 small Torx set screws, often siezed and the Torx head strips when you try to remove them.

I have VIDA dice and there is a program in there to back the EPB off, I failed to make it work and wanted the job done so reverted to the pp9 battery method.
