the MC won't build pressure. Tested it against the MC28 MC sitting on the bench, and the 28 is fine.
Are the guts of each the same, i.e. are they interchangeable?
Whats involved with rebuilding one of these? Looks pretty straight-forward, but the rubber boot on the bottom edge looks like a fragile part.
And finallllly, where can I get a rebuild kit for the stock MC21 rear MC?
Thanks all
Jeff
