This fekker is finally out!!!!! thanks to every one who helped!

brought the 4 piece halfrauds punch set. £6.99. did the job!
started with a centre punch straight doon the middle to shock any remaining rust off't threads. then used the pin punch to try and make a hole at the side to get some purchase on. didnt really work so i broke out the cold chisel in the set. 6 cracks at different angles with the hammer, screwdriver in. unscrewed! job done!!

couple of quick things..... as you can see from the pic there are metal shards. they got all over the disc and on the pad fronts. obviously i got the crap off with a rag and tissues but if there are micro particles would it be best to hit disc with brake cleaner?
how do i ensure its all off the pad material?
finally the slide pins. before, i took the old grease off and regreased up. fine. however the ''boot'' doesnt seem to slide back on its own. when the pin is pressed in it will slowly slide out but the boot will stay all crinkled up. is this a problem? i cant see it being a problem bearing in mind the boot is proper squished anyway when the caliper is done up tight but thought i'd ask
