First issue upper brake pipes rusted and rounded off. Added to the tool kit with some Flare nut spanners along with mole grips got them off.
The big issue was the access to the metal to hose joint through the bracket. Looked and tried virtually everything in the tool box to undo. A call for help went out and after a while on day two to my embarrassment the bracket i thought was welded to the sub frame was actually held on by one bolt which quickly came off with the remains of the hose and metal pipe.
After a overnight soak in oil, the use of a bench vice and a bit of brut force finally the pipe was separated and the bracket free also managed to save the clips. did consider buying new with clips would be over £50 so a bit of straightening and a dab of Black Hamorite already to go back on with the new hoses.
Hopefully as the majority of work left under the arches is a good clean and a bit of touching up should be able to manage that without any dramas.
