Re: Laguna 3 57 plate Rear discs and pads with electronic handbrake

If it is the single black box EPB that operates cables to calipers, nothing special to worry on.

If the electric motor types that piggyback the calipers, they need to be powered back with diagnostic tool.
Doesn't need to be a main dealer, most brake places and probably independent garages should have the kit by now.
There is a DIY way with battery and wires if needed.

I think you have the single box EPB so.
Leave the yellow handle alone... this disconnects the cables inside the unit and is in case of emergency only.

Chock, jack and support the rear end.
Manually release handbrake from dashboard.
Disconnect battery (radio codes)
Remove calipers, pads, discs.
Open fluid reservoir.
Wind back piston. Special tool for this although some do say that pliers or other makeshift tools work.
Do not push it back, wind it back.
Some recommend opening bleed nipple to help fluid escape rather then forcing it back through system.
Refit new parts.
Pump foot brake to advance pistons.
May need bleeding, for some reason my Scenic has whenever I've done pads even without opening the bleed nipples.
Battery back on and try handbrake.
Do not operate handbrake until foot pedal has advanced pistons.

Should all be hunky dory.
