I upgraded my discs and pads over the weekend to a set of Paul's very nice 330mm versions with some CL pads.
When I tried to remove the old pads they were jammed into the calipers thanks to corrosion, where the caliper has a stainless guide for the pad to run on, there was corrosion under the guide on the inside both calipers causing the guide to lift, jamming the pad in. This is probably why my brakes were juddering, they can't have been working very well.
Below is the corrosion after I had cleaned it up, gave it a wipe of copper grease and refitted the ssteel guide.
I guess the long term answer is to get the calipers refurbed?

That's galvanic corrosion, dissimilar metal corrosion. Clean it off, smear copper grease, and all will be good.
