As above, mine went in no problem.
Replaced the gubbed rear caliper this afternoon and have been left with a pedal I'm not particularly happy with. Tried pressure bleeding, pedal bleeding, even tried it with the engine running, but still it doesn't feel 100%. It goes rock solid after just one press with the engine off, but as soon as its running, it's kinda soft, not spongy and there is more travel on it than I remember (have been driving other cars this week which doesn't help!).
I can see me resorting to having all 4 wheels off in the coming weeks and connecting it to my vcds and doing all 4 brakes to see if that helps.
