It is funny that you say that. I considered putting on a mask when I sprayed the cleaner earlier, but did not, and regret it a bit. I hate breathing in chemicals.
The rear wheel is installed! This is significant. Everyone have ice cream tonight and it is on me!
I can say just after finishing that it is extremely difficult up until it actually happens, particularly because one has to feel their way through it at least once.
For assembly I put a car ramp in place and used wood blocks for exact spacing. I had a makeshift support stand outside for the caliper. So I never strained myself putting it together, like I did pulling it apart. Everything had a place to rest.
I do know that I pressed the sensor against the rotor a bit as the the brake alignment was off. I see people warn about this here and hope that it is not super sensitive to touch. It appeared unmarked.
If I lower the stand now the bike tilts forward. I have to get the tie-down more proper next time. This means I have to assemble the front to compress the bike and get clearance on those shock bolts. So much to do up front. But I do not think there is any assembly up front requiring the level of muscle and finesse that the rear took.
