       So still trying to figure out the picture thing, hope it's right
       this time. So what do normal people do to bleed the master
       cylinder when you don't have a major lift available? As we know,
       the manual says to raise the front end until the master cylinder
       is level in order to get all the air out. I use a small level to
       be sure. and a motion pro pressure bleeder at around 10 psi.
       Once around all the wheels is usually enough. For me, I can do
       the whole process in 30 minutes or so. Still a major pain in the
       arse.... >vom<

       I replaced the CB master cylinder in 1978 with a CV one - much
       easier to bleed, no jacking required! I have a servo disk/drum
       set up now with a Series 3 type servo/master cylinder. I
       recently did an overhaul as the master cylinder was knocking 20
       years old and used a Gunson's pressure bleeder - what a
       difference! Bleeding the brakes was easy, it was jacking up and
       getting the wheels off and on that was the pain.
       I had to use a spare cap as there wasn't one big enough in the
       kit - you just drill the cap as instructed - not a problem as I
       used the one of the old cylinder. I used a spare wheel off my
       Austin A40 (lighter to lift onto the wing) and used around 20psi
       (maximum recommended pressure) but would use a lower pressure
       next time - I think 10-15psi is ample. I just went round all the
       nipples twice in order with just a few seconds flow at each
       point. The second round was really just to check there was no
       remaining air.
