But as Dojj said check your hand brake cable is adjusted up correctly and that when the handbrake is applied its not slack on the side the side thats inop
Thanks for the reply, I have ordered a set of seals from bigred.co.uk incase I take it apart.
I will try and get some pics tonight. From what I can see pulling up the handbrake does move the armatures on both calipers by a fair way so I don't think the cable would be at fault. I've had the caliper bolted on without a disk and pulled on the handbrake and the armature moves round but the piston moves like 1mm or so, barely anything
I guess the pin inside may have broken as mentioned above although I have no idea what this looks like!!
