Nick Hood:
I am trying to loosen off the brake gland to bleed the brake.  It just wont move with a little spanner or mole grips. I have sprayed wd40 on it. Any suggestions ? Heat it up ?

MarkCR750:
Yes I would heat it up, try just heating the nipple, get it really hot then quench it, the expansion and contraction may just do the trick, failing that heat the calliper where the nipple fits , you do risk damaging the brake seal though, also a long socket may work better than a spanner.

PS I just realised you might not mean the nipple but further up on one of the connections, if that's the case don't bother , you'd be better off reverse bleeding the brake through the nipple using a syringe and tube fitted to the nipple.

Bryanj:
If its the nipple warm the caliper not the nipple and use a long socket with T bar to get an even undo as they shear easy

Nick Hood:
Thanks guys. I warmed it a bit then found a very small socket. Had never used it before. It did the job. Put new brake fluid in . The front end dives now but doesn't stop the bike lol
