Yes I drove it thanks, but not enough to recall pedal feel. I do know
that your brakes "grabbed" better. Like less effort, more positive
braking feel.
Ok. Read your email. Took it out for a spin.

Not really. Maybe a **little** firmer + higher pedal. Repeated
pushing, I hear the booster, but pushing fairly hard, pedal will go
down until I hear/feel a subtle "thud" as pedal stops.
Feels like air in system but maybe MC is faulty. Should be ok as was
new a few years/low KM"s ago but .... <shrugs>
Though I'm too precautious about not setting shoes too "tight" drum,
they should be ok. i.e. engine running, standing on brakes, set
e-brake, pedal stays same height.

No. Pump it a few times, hold pedal down, start, pedal sinks a little.
Help much appreciated,
Neil.
