Almost there....Changing the discs and pads on the back today. Removed the R.H. and found one of the caliper guide pins had seized in the carrier, gave it a good dose of Plus Gas and eventually worked it free. Ran a 10mm reamer down the hole to clear the ****e out and polished the pin, coat of copper grease.....sorted.:clap2:
Round to the L.H. rear, last one to do....both guide pins seized, one of them solid. Got the Plus Gas out again, had a fag and a cuppa, one came out with persuasion, the other solid as a rock, tried more persuasion and the feckin pin sheared off

So here's hoping the Main Stealer has the bits on the shelf, the carrier is around £35 and a set of pins around £12 according to the web. If not, I may take a trip to the breakers as the same caliper setup is on the Disco.2 and there are more of those than P38's over here.
All that's left now is Transfer Box and Axle oil changes.
