There is no pressure when i press down my clutch, I just had it replaced about a year and a half ago. It didn't feel like the clutch went?

Hi most chevy"s are fitted with a concentric slave thrust bearing. This normally creates hydraulic fluid leakage between engine block and gearbox bell housing if not so , check hydraulic pipe lines for leaks. bleed system and be certain hydraulic pressure maintains .If problem persists check and replace clutch master and slave or might be a rare case of a faulty pressure plate.

For what ever reason you have air in your system.. Could be a bad "new" master cyl.. Or a line could be lose and leaking fluid out and air in.. last year i replaced a brake master cylinder on a 1997 eclipse. It would not bleed correctly, would not make pressure... so i went back to parts store and made them replace it with another rebuilt one.. same problem.. I worked on it for a long time i had never encountered the problem before.. I removed it and took it back.. Same problem.. Everything else checked out OK.. The master Cyl come with a warning that if you take it apart they will not replace it.. I was at wits end.. "and mad as hell" I took it apart.. Inside the seal on the piston was not seated correctly and was cut from the grove in the piston.. I called the manufacturer. and they sent me one that they had checked.. WORKED GREAT.. So don't think that rebuilt parts are always ready.. I suspect the same rebuilder person had rebuilt all 3 of these defective cylinders.. Possibly on purpose.. since there would be no way to make the same mistake 3 times. I went through a gallon of brake fluid and about 15 hours of labor, and the embarrassment of not being able to repair a customer's car. When i showed him the problem he was very understanding.. I could not charge for all the labor and fluids.. It was not the customers fault.

Check your throw out bearing !!!

replace the clutch master cylinder. The rubbers on the piston swell over time and/ or break down blocking up the ports in the cylinder.. Wrong fluid is the main culprit for this type of fault.

You know the clutch is slipping
& continue to drive & ruin that

Now you can do another clutch
service, while your finding the answer
to what your asking

Next car get an automatic & just change
the fluid every 3 years

Sounds like the throw-out bearing or the pressure plate has gone out..

Unfortunately, it sounds like your pressure plate is going bad. That is the larger part in the following picture. When you depress the clutch pedal it pushes the throw out bearing (the smallest round part) against those center "feelers" and that disconnects the clutch (the next size down round plate) from your engine flywheel.

Normally you would replace all three parts at the same time.

Clutch pressure plate weak.Replace the whole clutch assembely.Hope this was helpfull.

you need to bleed the clutch system.. have someone pump the clutch pedal three or four times, hold it down and release the bleeder valve( make sure the person holds the pedal down till after you tighten the bleeder valve back down) repeat this four or five times or till the clutch pedal feels like it did before.. good luck keith...
