Well, you can feasibly do it without doing any of
that, but why would you want to make life & the job so difficult for yourself?? :dontknow: :banghead:
As far as I'm concerned, bleeding the brakes on your Spyder is generally a helluva lot easier if you can jack it up off the floor at least a bit & put it on axle stands; and even more so if you can take the front wheels off - it's a whole lot easier to access the bleed valves if you do!
And IIRC, you can easily get at the rear bleed valve with the wheel in place, especially if you're not lying on the ground searching for it! :thumbup:
