Hey Paul.
Did new caliper seals go in at the same time as the SS pistons and the
synthetic fluid? If the original seals were retained, the change in fluid
may have caused them to expand. That would certainly result in the
reluctance of the piston to move in either direction. However, first move
should be a pair of new fluid hoses at the front and re-bleed. As Michael S
suggests, that would be the most likely culprit. There seems to be a
reaction to synthetic fluid where the rubber has previously been exposed to
mineral fluids. New rubber everywhere is becoming the accepted approach.

Subject: Brakes Problem
Listers
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
Paul
