Brakes were great before i snapped the metal pipe on the end of the flexi to one of the front calipers. I fitted a new flexi hose the next day but snapped the bleed nipple at that caliper when trying to bleed it. I fitted my pressure bleeder and bled that caliper at the flexi union but still had a rubbish pedal. Since then I've done it the manual way with an assistant at all wheels, gravity bled all corners and pressure bled the system a million times. Is it possible air trapped between the flexi union and the bleed nipple could be causing this?
