You're most probably correct, Clan, and the adjusters are not the 'ideal', or 'absolutely correct' solution to the problem.

But spending £7 and one hour resulting in a working parking brake always beats removing old cables, buying new genuine ones, running them under carpets, around seats, through the floor, under the car and only then maybe achieving the 'same' result - an MOT pass in this case.

Not trying to be cheap, but adjusters are the way to go for me. Of course, after new discs/shoes are fitted and everything else inside the wheel works fine.
