had a go at old calipers and there staying put when i got the mud and rust away from the bolts there was nout to put spanner to and the rest of the caliper is rusted right up
so its back to the other calipers and finding out what pads they take
as for the feed i was thinking of taking the single flexi pipe down to bracket then splitting with T connector to the 2 feeds cant see it being a prob with mot as brakes will still work
