I've just finished fitting the replacement caliper, pads and discs to my car. A fairly easy job overall, most of the time was spent cleaning up the replacement caliper.

I've cycled the handbrake a few times and it sounds correct now (the first few times took longer than usual as expected). However, with the handbrake off and the transmission in neutral, I can't spin the brake disc (it's still jacked up off the ground).

I don't know much about the Quattro system in these cars - if the other wheel on the rear axle is on the ground, does the differential have some sort of lock that would prevent the jacked-up wheel from spinning? Or should the wheel spin freely? It feels as though the handbrake is not disengaging but it sounds like it's working correctly.

I've left it as it is until the morning. I'm hoping the new caliper is not at fault!
