Well; I got up at 5am before work to sort this once and for all !

Removed caliper again, took pads out and fully exposed the pistons.

Cleaned them up good and proper and pushed them back in again......

Squeezed the lever a few times and only one piston came back out again. Had a good look and i could see bits of seal trying to come back out with the piston....

So, decided to remove both front and rear caliper while im doing the front, and have sent both off them off for refurbishment. (If you click the link uptop in orange - theres a huge article about what exactly they do) For this price its not worth me messing around with them myself - its easier and less painfull to do a couple of hours overtime at work ! Plus a 2 day turnaround means i'll be back riding next weekend. Just another problem that hopefully wont ever return !

Very unhappy to report my front brake problems are back and even worse now. The lever will barely move. The pistons in the caliper move freely. It has to be the MC, but we took it apart last weekend and it looked fine. No torn seals or anything. So I don't know. I'm rebuilding the MC, if that doesn't work, I will send it off somewhere.

There may be a restriction in the hose.
It may have delaminated internally, possibly impact damagefrom trail debris.

We thought about that too, but we can back bleed fluid through the hose with no problem, it would squirt out in a nice little stream. So it appears the hose is fine.

We took the front brake MC off Paul's KTM and put it on my 300. Hoping to see if the MC was surely the problem. Hooked it all up and could not get the lever to firm up. We back bled it, front bled it, etc for 1.5 hrs before giving up.

I may send the whole assembly to my main GasGas guy in Houston. He is pretty good at fixing stuff I hear......

I may have my OEM caliper in the garage.
Lemme check.
