Heres the problem if i rev up the car with the pedal to the floor at the higher rpms the car tries to pull a little. I car feel the engine rock hard. It doesnt move the car but if i didnt have the brake on it would. I also occasionaly grind when i shouldnt. Ive had a similar problem before i wonder if my hydraulic system is starting to fail.

 

maybe its the clutch master cylinder?

 

cable or hydro, either way could be out of adjustment, also check your motor mounts, if not could be something more serious like PP out of alignment.

 

Has the hydraulic system ever lost pressure to the point of having to pump the pedal to get it to come back up?

The clutch hub and/or pressure plate also might be damaged.

 

i believe so but it was fine after that for a while.
