I'll pass on the wheelbearings then till I actually tjeck if they are alright or not. Quite easy and quick to pull both wheels off later on and who knows - maybe I never have to change the bearings on this bike anyways

Plan was to refurbish the brakes completely. It's been 3 years since the calipers where separated and cleaned thorougly so I think I might aswell do the whole chabang.
Hmm why not just buy them so I got them just in case the old seals are broken... why didn't I think of that before I asked
I think he was just making a point (using bearings as an example) that if it isn't broke, don't fix it...
I did not rebuild the master cylinder as there wasn't anything wrong with it. As for the SS braided lines, I just wanted to upgrade the braking system. I did take my calibers apart as they (just the fronts) were sticking/dragging. I might get 3/4 a turn (on the centerstand, front wheel lifted) when they were dragging. I should have replaced the seals but just cleaned and re-assembled with with brake specific grease :

If you look at the spec's its designed for use on the actual brake pistons.. It helps with re-assembly also... The wheel now spins at least 2 full rotations.
My 07 has 4 pistons per disc, I believe yours has two (each disc). When I replaced all the seals on my 04 FJR (4 pots per disc, same as my 07 FZ6) they didn't sell a kit, you have to buy each pair of pistons seals separatly. I had twice as many as you do and as I re-call, they were around $125.00 US.
IMHO, I wouldn't bother re-building the master cylinder unless there's a problem, leakage visual, etc. It'll drain when the lines get replaced with braided, you can gently blow air to remove any debris.
As for the pistons seals, if thier dragging a bit more than they should, go ahead and rebuild them (again, unless there is visual leakage).
If your bored and want a project, replace them, it certainly can't hurt and you know your good for at least two years... Definitly change the brake fluid in any case if over 2 years old..
BTW, when I put the old seals from my FJR next to the new ones, I could not tell a difference. Obviously, the rubber is newer and more pliable. The FJR was dragging really bad (maybe 1/4 turn) with the old seals, new seals/grease, 2+ full turns..
