Custom cut a plumber's insulating mat, bit of tentative hot and cold ( possibly too tentative since I'm being v. cautious), but flare nut still is seized on the pipe.
So my idea was that if the flare nut was stuck, why not just rotate the flexible hose out instead? With care not to crush, I put a mole wrench on the metal collar of the flexi pipe ( due for replacing anyway ). It rotates easily, but only about 1mm either way and then seems to lock. What is stopping the rotation of the flexi-pipe or should I be able to turn it now the connection is released  ?
Still trying to avoid brake pipe renewal as the rigid brake pipe is fairly new and looks OK. New respect for those who earn a living working on brakes  |
The flexi is locked in to a star shaped keyed hole in the bracket if you mean the end by the rigid pipe.
It might turn a very small bit then stop, but shouldnt really turn at all.
Depending on what job you are trying to do, if it is removing the caliper, i usually manage to unscrew the flexi from the caliper by swivelling the caliper around once its unbolted from the carrier
