Response to PM.

I would never advocate rebuilding a m/c cylinder on a whim - but I don't know your level of expertise and you may be more than capable.
I now suspect you have moved the brake lever beyond its operating window - there are clear min/max points - and I would readjust that back a little (if only to eliminate an issue) as your problem does sound so much like hydraulic locking.

There are other areas I'd personally look at but this is a good start point.
I'm thinking you do know you way around brakes and have check the slider pins and pads in forward etc.

Sorry mate, still learning this stuff :-). Greased slides, master was easy job really,  tho dave silver advert said 59 quid plus vat earlier !  Now i find out, was quoted 140 plus vat from 21stmoto - hence kit first eh. Pistons look clean in unexposed areas and moved freely before the surgery began, but now, with hydraulics backed off only ! Wonder if the master is just dodgy somehow ? As i say, only one hole is visible in the bore of the master adjacent to the supply elbow outside ! :-(
