Front pads, max 30 mins each side I reckon, with an hour and a half to do the rears in total. My front discs look shot, the pads look fine and rear discs and pads look hardly worn. Seems an odd combination to me, how long have yours lasted?
I timed myself at 100 minutes for all four discs and pads. That was on the floor jacking 2 a time using a trolley jack and I'm an IT software consultant, not a mechanic!! Rears should be exactly same as fronts as inboard drum handbrakes don't require caliper windback. I didn't touch the drum shoes though.
Discs take around 5 mins per side extra, absolute tops, just FYI.
Rears are easy, just a PITA trying to get the handbrake set up again, you have to flick a star wheel round through one of the wheel bolt holes, certainly no more than 1 to 1 1/2 hours for the whole job.
