Re: brake master cylindar
Well unless you ran your brake pads down to half.
There is another thread running on brake bleeding, and apparently you are supposed to wait 10 minutes the first few times between pedal presses to bleed the brakes, so maybe the bore wasnt completely full, fill it up, and keep an eye on it, if it drops again, take it straight back and tell them.
If it is stopping ok dont panic to much, just keep checking it.
I did put something here, but it vanshied, I think
"So long and thanks for all the fish!"
