Bill, many thanks, and I would appreciate the master cylinder kit part number if
it is handy.

strike at the house I am still recovering computer files so I don't have
pictures or the kit numbers handy, but if you need them I can find them as I
keep paper copies to. I get the kits from my local NAPA. While you are there
replace the flex hoses, I use Triumph Spitfire rear hoses on all 4 corners of
the Berkeley, they are slightly longer but thats OK.

In the old days I would have honed the cylinders.
