Trying to replace the rear discs on a Rover 600 (they're corroded).
The caliper mounting bracket is fixed to the hub with two 14mm bolts, which are incredibly tight. I've got the top one off (nearside), but there's no room to get a socket on the bottom bolt. I extended a thin ring spanner with a length of pipe to get more leverage but it just bent the spanner and the bolt didn't move.
It's not rusted on, just tight (the thread on the top bolt was bright and shiny, no sign of rust or loctite). Any ideas how to get this undone? I've tried soaking it in WD40 and hitting the end of a spanner with a hammer, with no luck.
Thanks,
Hofman
