I did mine this w/e. I'm the slowest of slow things on an official go slow, so I suspect
anyone else would be quicker. I also admit to having had a mate help on Saturday!
Friday spent about 8 hours. Essentially just removed and replaced the fronts....though actually did the left side twice cos I made the elementary mistake of initially fitting the rh disk on the left....didn't relise they were handed til I got to the second box and wondered what the felt tip "GL" meant written on the lid - and then saw a GR on the other box already fitted - doh! Still it only added about an hour.
On the Saturday Pete and I did the rears in about 6 hours. We did a fair amount "together", but some of the time he was working on the right while I was working left so there was definitely added manhours - maybe as much as a 10 hour stint if it had been me alone? The rears were much more difficult because it meant replacing the hub and bearings as well as disks and calipers. We also did the first round of bleeding the new system...
...but it turned out to need at least two rounds of bleeding and then the handbrake adjusting which overall took me another 4 hours on Sunday. Haven't yet bedded in or even road tested!
So that totals up to maybe 20 hours or more. If you ask a professional, they'd probably quote about a tenth of that for the whole job. But then they would have some obvious method of (eg) getting the rear bearing shells into the new hubs without having to think up or make a tool! They'd have enough stands to take all four wheels off at once (instead of one axle at a time - takes about 20 -30 mins to swap ends), and so on. And of course I'm as happy as Larry pottering about in the barn and have no incentive to rush, whereas to a professional its just another job to get out of the way.
Oh and quick edit to say thanks again to Bob. Great kit ,,,,,
