And No.
I find vacuum bleeders brilliant for maintaining a constant steady flow of fluid while I go round and encourage the bubbles to let go of the sides of tubes, to move round n bends an u bends, and to stop hiding in the corners of joints.
But for bleeding the last visit to each bleed valve, no. The air sucked past the bleed valve threads means you cannot tell whether the lines are free of air by looking at the bubbles coming out. There are always bubbles. So use it to do the heavy work, use a bleed valve for the final finesse.
If you are checking whether it is physically possible - yes. The only complex bit is the fluid from the brake pedal, through the SMC to the rear outer pistons - and even that is straight forward - as the fluid just pushes past the primary seal of the SMC. Although the SMC is in a better vertical position on the ST1100AY than it is on the 1300, it is always a good idea to exercise its full movement with the rearmost bleed valve of the rear caliper open.
Check the movement and the bearings in that 3-hole linkage casting too.
For anyone looking in, the layout of the calipers and hydraulic lines on the St1100Ay are pretty much the same as on the 1300.
