I need to get the rear brake hoses off so I can clean up the mounting bracket and fit new hoses. What's the best method of undoing these unions?
The pipes are copper but everything else is steel and it looks like rust will cause problems. I'm not sure if I should give it a liberal dosing of Plusgas or whether that will risk contamination.
I've only got open ended spanners - do I need a special brake spanner?
Advice please.
