basically what you need to do is undo the short brake pipe from the cylinder to the flexi with a 13mm spanner but give it a good waggle back and forth to free it off.then get some vise grips on the metal part off the flexi and try to undo the nut on the other side of the bracket(wd40 helps alot here)you dont need to take it all the way off though.There is a peg on top of this bracket that needs tapping off but if youve undone the nut far enough it shouldnt be a problem.the flexi should then slide done and you can use it again on your new absorber because the brackets not battered.did it the other day on mine not to bad.
