I replaced every part that come with the clucth from the master cylander to the release bearing as well as the pressure plate i cannot get enough pressure build up to release the clutch it starts to build pressure but stops at a certain point of pressure there is no leaks

It sounds as though the clutch pressure plate has become weak.

When you press the clutch pedal the release/throwout bearing presses against the centre of the clutch pressure plate. This causes the metal 'fingers' -the springs- on the pressure plate to flex and release pressure on the driven plate - momentarily disconnecting the drive from engine to gearbox.

A weak pressure plate isn't fully releasing the driven plate. If you're going to do any replacing of parts - a clutch should be replaced in 3 units: Pressure plate, driven plate and release/throwout bearing.

sounds like thrust bearing or bearings in gear box

I hate to say this some clutch plates you can not tell the difference from the flywheel side so it will go on backwards ,sounds crazy,but I have seen people put them on backwards all the time and that is what it sounds like considering you have done enough for it to work,FLYWHEEL SIDE XXXXXX

It may be a defective clutch pressure plate release bearing. Have a local shop listen to the noise to confirm this is the cause.

If the slave cylinder has been replaced twice why did you do the master cylinder?If anything it behind the master at the clutch pedal, for the sake of trouble replace the line

if you have a manual transmission, adjust the clucth pedal - if wont work? replace your pressure plate, clucth disc, and the release bearing.
i dont have any idea on automatic transmission.

the price of the clucth disc is $116.55,pressure plate $76.03,release bearing$47.09.maybe your clucth disc is worn out already.you need to replace the three item to give a good perfomance

Put the pilot bushing in the crank shaft, install the flywheel. Next put the pressure plate back on, but leave the bolts loose so you can use the plastic alignment tool. Insert it through the pressure plate hole, and into the pilot bushing. Then tighten down the pressure plate bolts, and remove the tool. Install the throwout bearing on the clutch fork, and you are ready to go.

Sounds to me like clutch is not freeing up if you turn off motor & it goes straight into gear. Did you replace all clutch parts plate pressure plate & realease bearing its almost like there is not enough travel on master cyl or slave cyl if clutch is OK
