Finally getting back down in the garage today. Left the heater on this morning to take the chill off. First up was to remove the stuck calliper and fit a pair of fresh rebuilt callipers. All went smoothly these things are so heavy to handle.
I then took her for an extended test drive, could still feel some air in the system so that will need another all round bleed. I also got the tracking sorted so she now points the right way. Notice the rear camber due to 19” wheels the norm is around 2*

I then did a further two laps of my local ring road to bed the brakes in. One disc had a stuck pad mark and the other side was suffering with the stuck calliper so now she feels tight with no pulling sideways. I even had a chance to take a quick snap. Right height looking spot on now.
