Ok, I had a siezed bolt on the master cylinder (the one that secures the pipe into the cylinder). It wouldn't some off with any spanner & was way too close to other things to heat it up.
So i used some electrical componant freeze spray. It freezes things down to -56.
Spray the item, then put the spanner on the bolt (while still very very cold) keep trying to undo the nut, then as the 2 metals start to return to their normal temperatures - Hey presto the nut starts to come off!
Hope this helps people, as i was messing about for a whole day before i tried this idea!!
