James, I would agree with other comments that it would seem like you've got air trapped in the fronts.
I've just been through a bit of a similar Saga with my wifes MGB... new brakes throughout and couldn't get more than half a pedal.
We solved the problem by removing pads, had an assistant pump the pedal gently a couple of times to get the pistons almost all the way out so we knew the caliper was as full of fluid as it could be.
Next move was to crack the nipple and then compress the piston back into the caliper to force the air out.
We did this twice to both pistons in each caliper and hey presto a rock hard pedal.

I thought as much, Stock type master cylinders would be designed to work with rear drum brakes. The bore size probably isn't optimum, and you would normally have a larger reservoir as you get more fluid movement with a caliper than you do with a wheel cylinder. Personally I would change the master cylinder for the correct type especially if you think it might be leaking.

The popular type to use is a late model Mopar aluminium unit. You'll find them listed by Willwood and Strange among others. Strange B3360TA or B3359TA depending on how many pistons your rear calipers are. Hauser no doubt have a variant in stock. They are 2 bolt rather than 4 bolt so you have to make an adaptor, no big deal, I'll sort you out a link.
