You still have air in the system. Keep bleeding. The reason the bakes pump =
up in 2 to 3 strokes is that at that point you have compressed the air enou=
gh to transmit force to the fluid.

Subject: [Healeys] BJ8 Brakes
At my wits end with this problem ...
The brakes on my BJ8 have always been hard and bit well with little pedal m=
ovement.
Changed out the front callipers (to 4 pot) and the problems started.
After repeated bleeding on first push, pedal went to the floor.
After 2/3 pumps the pedal came right up and held. After about 30 secs of n=
o pressure on pedal goes to the floor again.
Pistons are all in contact with pads and pads with disc; all looks good at =
callipers.
Suspecting a faulty MC changed it out.
Primed the new MC with fluid prior to installing.
Same story after another 1.5 pints of DOT 4 fluid focusing mainly on bleedi=
ng front callipers and booster (new); also bled rear drums.
Pedal still goes to the floor on first pump and comes up after pumping as b=
efore.
No visible leaks and inlet from reservoir shows no leaks: tapped callipers =
with mallet to dislodge any air pockets.
I am using the one man bleed system a with clear tube into a container and =
close the bleeder valve with no visible air at nipple and full tube of flu=
id to container. BTW also changed clutch MC at same time and no problems wi=
th bleeding etc.
Have now run about 1.5 pints of fluid through the new MC - perhaps am bein=
g too impatient ?
But no evidence of any air after about 0.5 pint. Typically how much fluid i=
s required to clear air from MC and lines ?
Now sort or suspecting the inlet to MC from reservoir but for life of me ca=
nnot see how air can get in with no visible fluid leaks,
Any ideas from the more AH experienced listers appreciated.
