Ah ok, I think I understand what you mean. I was thinking about the solid pipes on the rear beam, but because they're all bent to shape before they're clipped in they don't budge. I didn't really consider whether the front pipes could move.
I think it'll still be a toss up whether I go for that and deal with the inconvenience, or whether I drop the beam to make the job easier and deal with the brake bleeding afterwards. I just really don't like messing with brakes!
