i replaced both my master and slave cylidners a few months ago and everything was workin good...it may have needed to be bled a little bit more but it was workin fine. just the other day the clutch started losin pressure and it was hard to put into gears the next morning it was impossible and it had lost all pressure and the fluid was all gone...do you think its one of the cylinders again? because i checked and there was no brake fluid on my firewall and none on the ground... any ideas? thanks
