I thought that the VAG stuff had the motors built into the calliper's, so no cables.?? Mind you which ever system, both crap and much o money o to repair

It is nothing like a Vag, or should that be VAG, the handbrake motor pulls cables which operate a good old caliper very much like my Vectra C had with its hand operated fly off handbrake and to rewind the caliper pistons you simply a grab the piston with mole grips and wind it in, OK a fancy tool might be handy but a nail bent to a U shape to fit the caliper holes and the ends cut off will jam in the pistons holes and turn it with pliers etc the last couple of turns where the seal stops you getting a grip with the mole grips.
The only problem is a stupid damper extension of one of the caliper slide bolts, I couldn't figure how to undo the damper until I realised unlike every other caliper I had ever seen the nut on the inside can turn and does not butt up against a projection, hence you just undo the inside nut with a spanner and the damper bolt unscrews with your fingers.
Overall the electric handbrake is a total pain maneuvering in hilly pub car parks becomes a matter of Russian roulette as to when/ if the handbrake will engage/release, but at least changing rear pads is not a problem, lucky really as my rear pads had only done 20K from new.

Mole Grips.. Nice to see the profession still has high standards

I actually printed out this procedure and followed it before changing my pads and discs. However, after a ten mile test journey, one disc was nearly blue! I've bled the caliper and I've taken the cables off again in service mode, reattached and have left handbrake off overnight to see how it is in the morning. ?

I realise this thread is a couple of years old, but I found it very useful... in fact I don't think I could have done the job without it. Just a couple of points to add though in case anyone else follows it in future - these maybe obvious points but worth noting. 1. The lower brake caliper vibration dampener has to be removed - this needs a 13mm flat spanner. Its a poor design, because its too easy to round off the flats. To preserve the flats I used a stillson on the round section of the rod behind the flats. Its not ideal, but does save the flats for doing it up properly. 2. When you do the wind back make sure the piston ends up with the two recesses aligned as in the pic below. The inner pad has a raised stud which needs to slot into the piston recess. Attachment Deleted3. Make sure you put the pads the correct way round - the inner pad has the single raised stud - lower one in picture, and the outer has two raised studs - top one in picture.
