[Healeys] Fwd: [Spridgets] Big Healey long shot.

Mike and Alan, I know this is not really answering the original question but
as far as I'm aware the condition of the bore of the 100 master cylinder is
not really critical. 
That style of master cylinder uses a stationary seal through which the
piston passes when the brakes are applied so it is the surface of the piston
which must be in good condition. 
Fortunately the pistons are relatively inexpensive to have hardchromed and
ground back to size.

Mike -

The brake master cylinders used on British cars in the early 50s can
all look quite similar but in fact can vary quite a bit.  For example
the MC used on my '52 Atlantic looks similar to the MC on my '53 AH
100 but in fact they are totally different - the stop lamp switch on
the Atlantic screws into the back of the MC whereas on the 100 it is
located remotely.  This is significant because mechanically the two
cars are identical otherwise.

My suggestion to you is to have the original MC professionally sleaved
(with SS) and rebuilt by a rebuilder.  That way you'll never worry
about mixing and matching incorrect components - which is a bad idea
when it comes to your brakes.

Incidentally, one of only 4 Singer Rapier Convertibles ever made by
the factory is undergoing complete restoration here in Hong Kong.

Best,

Alan
