release the handbrake
unhook the cable from the swinging arm on the caliper - itll then stick on the caliper through hole itself - spray with penetrating fluid
under the exhaust heat shield is a 13mm bolt, loosen this until there's plenty of slack to get the cables out
unhook the cables from the equalizer
Knock the cable through the caliper (takes some welly)
to fit, it's generally the reverse, although it should thread through the caliper through hole easily.
To tension correctly, tighten the equalizer until the lever takes only a click or two to be effective - there's a trick to it that I can recall, not difficult to trial and error.
