MGB Calipers

[John Caffrey <jdc6@lehigh.edu>]

While reading back through articles on Project Midget in Classic 
Motorsports, I see a picture of the B calipers they've just rebuilt. The 
relief on the piston is shown 90 deg. away from where it would be 
positioned on the Spridget caliper. I don't have a B workshop manual, 
and would like to know if they made a mistake? I don't know why the 
relief's position wouldn't be the same for the Spridget and the MGB.
