Once the system becomes pressurised you need to find out where the pressure is held by cracking open some of the joints.
If you undo the bleed nipple and it fixes it the pressure is in the caliper, if you undo the brake hose the pressure is in the line, and if you undo the reservois end the pressure is in the master cylinder.
Only then can you start to work out whats happening where
Only seems to be doing it once the brakes have warmed up a little probably after a mile of driving. Checked the hoses and none are kinked. I've checked the ressy and it seems to be breathing ok, i can blow throught the hole in the cap, and they brakes stayed seized even when i took the lid off. The only way of unseizing them was the crack the nipple off on the caliper. The feed line from the ressy to the master cylinder is quite long and is in a kind of u shape at the back of the bulk head, I'm going to shorten it and see if that makes any difference.
I'll keep you posted, thanks for your help so far!!
Kind regards
