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. |
