Hi Bill
I can't debate the point on a drum brake stopping a car just as well as
discs, I would question whether this held true in the rain or after passing
through standing water. The main advantage of discs is the repeatability of
stopping several times in quick succession, and the availability of linings.
Stock linings may stop equally well, but how about Green Stuff for Herald
front drums, I know it is available for the Disc pads, and I'll wager that
will always beat drums?

Hi Graham,
Early disc braked Heralds used a master cylinder identical to that for the
clutch, except for the increased height of the reservoir - this type is
indeed very scarce. Later cars used the standard drum brake and clutch type
master cylinder in conjunction with a plastic extension which increased the
volume. I'm uncertain of the change point, but I think this would have been
standard by the time Eduard's car rolled down the line. There's actually no
problem in obtaining the original clutch/drum brake master cylinder, the
right angled reservoir type is simply a cheaper aftermarket item which is
also readily available.
I agree to a point, but I have found repeatedly that a drum braked Herald
will stop far quicker than a similar car on discs. Where drums lose out is
on the regular adjustments which are required. Drums are also more prone to
brake fade when hot, so no fun on long hills. The early disc installation
with type 12 calipers I would not consider to be any improvement over drums.
Cheers,
Bill.
