Hi Paul,
You do not mention anything about replacing brake hoses.
I would definitely suspect an internally collapsing hose with these
symptoms.

Last autumn (sorry, fall) My BJ7 gradually developed a braking problem.
Apply the brakes and the car dives to the left, but lift your foot off and
the
car lurches to the right, as if positive pressure is being applied to that
side (not just in response to steering compensation). The car has been
driveable - but with care!
In the UK we have to go through an annual test and this involves a rolling
road - car failed last week.
The results show that there is poor braking performance on the right side
and
slow disengagement, again on the right side.
New stainless steel pistons installed to front calipers two years ago.
Synthetic brake fluid used.
Rear brakes overhalued in the winter. New rear brake cylinder to left side.
System partially bled.
Anyone had any experience of this lop-sided situation, before I get to grips
with tracking back through the brake pipe circuits.
Many thanks and happy Healeying

I had much the same problems earlier this year...
I, mistakenly, started at the front although the callipers did need an
overhaul. Yes, I split them and yes, I put new rings/seals inside. (The
stainless cylinders I was sold about 2 yrs ago turned out not to be
stainless!) The car, a MkII BT7, stopped quicker, but still pulled to left.
Never dived, but just pulled a bit.
So, I did the back. New cylinder rubber etcetc. Still pulled, but better
after it all "bedded in".
At the MOT the other day, the mechanic adjusted up one of the rear drums and
that was it...no more pulling.
I cross the mechanic's hand with silver from time to time......I do all the
work on the car myself, but am no more than a gifted(?!) amateur. He is a
pro and has the knack of seeing a problem and curing it in about 5 secs. It
should be irritating, but it isn't.
Maybe your car is in a similar state......try adjusting the rear drums.
The slow disengagement points, of course, to brakes. But, if the brake route
is exhausted, the experts will tell you to look at the right rear suspension
for leftward lurching and vice verca.
I'm in Devon and you?
Good luck. I'd be curious to know how you get on.
Simon.
