there's I found that after removing wheel, remove brake carrier
compleat with calliper and tie up to spring. If you look at bottom
of back plate, there is a slot ,If you use tuning fork joint remover
upside down it fits around ball joint, and as you whack it, it slides
up w/b freeing joint (hopefully) I used 17 19 21mm sockets and
large bar, wire brush plenty of plusgas. Had to cut my nut off b/j
new w/b did not come with nut what a joke

no new nuts. Any body know where (who) sells them, going to
buy used ones from Bongo Spares. spent few hours looking no
luck, even Ford and Mazda could'nt help.
