You'll need a non ABS prop valve from a US EK, you'll need to make up new lines to the front brakes and to the MC, however the rear brakes. You'll also need new brake fittings. Basically you remove the ABS pump all the lines and make up new ones which go direct to the brakes and MC instead of doing through the ABS unit. Hardest thing is the bending of the brake hoses.
Regarding MOTs, i'm not too sure how legal it is, but you'll need to remove the ABS ECU (which is under the dash on the drivers side with a large orange plug doing into it) at minimum otherwise your handbrake light will be on permanently.
If you need more info just search on google "Stevenek9 ABS removal" as Steven has done a rough guide on a few past threads.
