Hi Alan, I think you are correct in your assumptions about the
cylinders. The Command Car always pulled to the right on heavy
braking, which I assumed was either incorrect adjustment or slight
contamination of the left hand linings with fluid from a leaking
cylinder. A couple of years ago I stripped and cleaned all the front
brakes, washing off the contamination, replacing all the pistons,
seals, and boots, and doing a by-the-book adjustment of the shoes.
SInce them I've done about a hundred miles so any surfact contamination
should have been removed anyway.

Problem is that the thing still pulls heavily to the left, and the only
reason I can think of is that it might have two 'left' or 'right' hand
cylinders so that one is acting the wrong way. This is the only real
mechanical deficiency with the Command Car so I'd really like to get it
fixed. I plan to take it to a garage with a set of rolls to find out
if the braking effort is 'high' on one side or 'low' on the other, so
at least I nkow where to start, but probably I should get a new pair of
front cylinders first just in case.....
