[Mgs] Replacing Brake pads on an MGA

[Robert J. Guinness]

Does anyone have any practical tips on replacing the front disc brake 
pads on an MGA?  I cannot get the new pads in because the space taken by 
the old pads is not wide enough for the new pads.  The manual says to 
clamp the piston, but any clamps I have get in the way.  Anyone have a 
web reference to a video or photo references that may help a first-timer 
through this process?  Thanks.
