Manual front Disc Brakes?

How fresh is your system,(new wheel cyls.,bled/fresh fluid recently,etc.)? Make sure none of the wheel cyl. pistons have frozen-up on you, good pedal but no apply. I'm dealing
with actually clogged lines right now on my GT 'vert, the master leaked out the back, I just filled it to move it. Always had a pedal, stopped marginal tho', now I'm redoing the stk.
system temp., only one Rr. piston was moving & after bolting in the master wouldn't bleed. The bottom of the old res. looked like a dry lake bed, and muck is in the lines. I've
managed to clear some, but will just change the line to the rears vs. playing around, no flow at all.
