Erm, but a G-Clamp can, and quite often would, damage the face of
the
piston as it would be able to rotate on the face of it without
actually
turning the piston - because they don't have the 'pins' to lock onto
the
piston as proper tools do.

Actually the average G-clamp is designed *not* to rotate on the
'work-piece', so the only force most G-clamps will apply is a pushing
force and not the (in this case) rotational force required to wind the
'outer' piston back in.

I've always found that they 'stick' a bit and will rotate.

Mind you, in this case, you're relying on the rotation of the clamp to
wind the piston back in.

So, if it doesn't rotate, you're going to damage the threat / ratchet on
the caliper, and if it does rotate, you'll be grinding away the face of
the piston.

There's ingenuity and there's bodging.


Exactly.
