Firstly whoever last changed the pads hadn't lined the cut outs in the piston with the raised bump on the inner pad so I had so major funny shaped pads and knackered discs (and no doubt reduced braking efficiency!)Wound the piston back, fitted the new pads and then discovered my handbrake wouldn't work, far too many clicks and wouldn't hold the wheel.
Did a bit of digging last night and found that after winding the piston back in it needs to be wound back out 180 degrees to reset the handbrake mechanism before refitting. Did that this morning and foot brake all good however when I reconnected the handbrake cables one side was locked up completely (no handbrake applied). Removed the centre console and slackened the adjuster off a lot and both wheels free to move.
Issue I'm having though is the equaliser bar is pulling one cable more than the other when you apply the handbrake. Also one side is not fully releasing, I have to push the cable back through by hand to release it or reach under and do it on the caliper. If I disconnect the cables the handbrake arm releases fine so I'm guessing I'm going to need a new cable?Strange now some guides mention winding the piston back out 180 and others don't.
There was no way I was getting a working handbrake without.
