1G clutch not working and ive replace almost everything

[1PhAtGsT]

I have a 1990 gst and ive replaced the slave cylinder, the clutch master cylinder, blead the lines adjusted the clutch master cylinder all the way out and even put the extension rod on the slave cylinder and you have to press the clutch all the way to the floor to shift gears i also put a new act 2100 clutch in and had the flywheel machined down do you think they could of machined it too thin???

thanks for the info

They could have. Didn't you check the step height after they did it?

maybe you got a leak somewhere, check the main hard-line and the rubber line

I think you may be blocking the fluid feed to the master cylinder. Put the stock pushrod back in the slave, and adjust the master back down to where it's supposed to be, and see how that goes.

That is likely the case. Does sound as though he has things adjusted way too far out. But not likely the cause of the low pedal. A system that is put in cut-off will be overly efficient. Giving you more output than normal.

Overtime, as the clutch wears, the system won't be able to compensate and it will start to slip. Thus, the cause of most burned out clutches on vehicles with low miles. People that ride with their foot on the pedal constantly can induce this.

ive had this problem many times.....the way i have fixed this is by gettin a 3/8's socket and put it in between the pushrod and the lil cylinder inside the slave cylinder.....then grap some washers and put them between the slave cylinder and the transmission to give it some extra clearance......i can try and explain it better....but just let me know if u have any problems and ill try and explain it some more....

Completely drain the hydraulic system, replace the longer SC rod with the OEM one and bolt the SC back on. Screw the adjustment rod of the MC back in - until you see the clutch pedal going down, then stop. Bleed the hydraulic system, don't touch the adjustment rod of the MC and just unbolt the SC, install the longer rod while being careful that no air get inside the hydraulic system (= the pistons doesn't slide out of the cylinder) and bolt the SC back on. You should have no disengagement problems at that point - and still are going to be able to raise or lower the engagement point.
