Since no one else has explained this, I'll put in my 1 1/2 cents worth (not
worth two whole cents). Back when I was fiddling with the dreaded MGA
coupe's brakes, I discovered that the hand brake actuated the piston in the
wheel cylinder instead of spreading the brake shoes by a separate mechanism.
I can't remember the details of this and no longer have the car to look at,
but I remember thinking that it was a stupid design. I can imagine that
stepping on the brake pedal, which moves the piston out, and then pulling up
on the handbrake, which would move the piston some more, could cause the
piston to be overextended, but I'm not sure how this would make the brakes
stick on.
