440 GLT 1994-Rear Disc Brakes-handbrake adjustment!

[booker]

Rear disc brakes on my 440 have a handbrake lever-arm with the handbrake cable attached-both sides of course. The lever-arms,which are spring loaded- for return-, apparently move the caliper pistons to lock the pads onto the rear discs when the handbrake is applied.
I have located an adjuster on the inside of each caliper near the handbrake lever-arm which is hard to figure out i.e. how does this thing work? how do you set the handbrake up properly? The adjuster is a 4mm allen head recessed screw which moves about 180 degrees from stop to stop-no more
Currently the handbrake can be fully applied with no braking at all.
1.The pads have about 75% life in them-plenty of thickness there.
2. The arms are moving properly on both sides when the HB is applied.
3. The pistons are not seized as I have tested them for movement when the footbrake is applied.
Any help,comments for the adjustment technique is very much appreciated (asap).

Thanks billofdurham, for the pdf as it helped-sorry for delayed reply. What I found though was that the 4 mm allen screw that adjusts the brake pad against the disc was partly seized along with the interior working mechanism. I had to purchase a new caliper-here in Australia $200.00- had to bite the bullet as there seemed no easy fix on this thing

Thank you for the update.
