So my clutch pedal keeps going out..I have replaced slave cyl and master.and the clutch, pressure plate, also throw out bearing and pivot ball...wth am I missing. Clutch is good then is gone..someone help

 

Did you bench bleed the master cylinder? I suspect air in the lines which is impossible to be rid of if you don't bench bleed the master before install.

Also if you replaced with a used unit, it could be bad from the get go.

 

so my mechanic did the install i asked and he said he did bleed it..so im still like idk im gonna try and replied system again and add high performance braided clutch line...any good ideas on how to bleed in situations like this???

 

Is the master new or used?
