i had new synchro's,clutch.flywheel,tranny mount installed.
they day i got it back the pdeal was acting funny.
there wasn't a lot oif pressure a the top of the pedal.
after about 20 miles the the pedal didn't even have enough pressure to come back up.

so i took it back to shop and he said cause of the exedy clutch something happened where it broke my clutch master and slave cylinder. so i picked them up at a local auto parts store and there suppose to be installing them now.

Default Not the Clutches Fault!

i am strating to think these guys dont know what there doing.
If they are blaming the new clutch for your master/slave cylinder, then there is a good chance you are right with the above statement. I don't see any reason why a new clutch would cause a master or slave cylinder to go out. The way you described your peddles' actions It sounds very similar to what mine was doing after a warrany clutch replacement. In my case the peddle went super soft and light with very little feel. Ask them if they tried bleeding the clutch. If they did, aske them to do it again. These things can be a pain in the Ar$e to bleed properly. With my case, I did end up putting in a new master and slave in eventually and it works great now. Both were under warranty. It could be that your hydraulics are shot, but I don't personally belive that it can be attributed to the new clutch. Maybe its simply a bad clutch installation and the throw-out bearing is binding?????
I would investigate this furture before you go out and pay for a new master and slave.

Hope this info helps..

Pedal pump bleeding method is probably at fault. What happens is the slave and master cylinder bores develop a ring of corrosion where the seal stops with normal travel. Under normal use this is not a problem. But when the pedal is pumped to the floor to bleed the system the piston and seal travel through this pitted area damaging the seal. This is why the pros like to use new parts. Pressure bleeding, also favored by the pros, is another way to avoid this as no pedal travel is involved. Except on our Subarus I think clearance from the firewall might be to tight to fit a pressure cap on the clutch master. Fluid change every two years along with the brakes also helps to minimize corrosive effect of contaminated fluid.
