A3 rear calipers and hose replacement

[johnny2007]

Hi everyone, I am about to attack this task on Saturday because both calipers are totally seized and I got new ones cheap from GSF (£30 Febi).
Done this before on other cars, but this is well rusty, anything in particular I should make sure I do?
I'm a bit concerned about the hoses bolt that looks very rusty.
Any advice on removing them safely?
Thanks

Those pipes shouldn’t really be much of a problem. A drop of penetrating fluid on them and use a pipe spanner on the nuts. Jiggle the nuts back and forth as you are loosening them instead of one steady pull and they should undo pretty easy.

Is the pipe spanner essential?
I don't have one.

A quality pipe spanner is a good move.......I have a Halfords Professional one, nice wall thickness etc.
On difficult pipes I've used Mole grips if the spanner jaws had a tendency to spread.
Curious - I thought these cars had a banjo bolt system on the rears!

Give it a good soaking in Plus Gas before you start then grab a cuppa to give it time to soak in.
