I'm thinking new mechanic too. RKTNMYPKT I've got a bit of a bung right leg too, my foots turned out so its a hassle to apply any foot brake so I know what your talking about there.
Something that may be worth checking, and I'm going to have trouble explaining it so bear with me, is when I replace my rear brake pads sometimes I get concerned that one of the pads is not sitting properly in its housing and I've nearly put it back together a few times with one disc not sitting on its step, like its sort off fallen down. I now double check it every-time I do pads. If this is your case it may explain the heating up. The ABS may be a different caliper from the stock too? not sure. I could be wrong about this but its seems a hassle to get the pad located, if you had a mechanic do this a while back (and its the sorta job they give the apprentice) they may have slapped the pads (or a pad) in and not checked that it was located on the step. Every time I do rear pads this annoys me, front are a breeze.
