we have a 1989 chevy 1500 truck and we have bled the clutch several times and still no clutch we have also replaced everything brand new and still no clutch can someone help us?

You replaced the master cylinder, the slave cylinder and bled the whole system? Are you sure the problem is in here, or in the clutch itself (throw-out bearing, diaphragm, pressure plate, disc, pilot bearing)? Have you checked the rest of the system?

I'd suspect throw out bearing if there is a lot of noise, especially when the pedal is depressed.

Unfortunately you have to drop the transmission and spin the bearing by hand.
It should be rough and making noise if bad.

If you have absolutely no clutch disengagement at all then the problem has to be hydraulic. Look for signs of fluid leakage from bottom of bell housing, from hyd. hose and fittings, and the clutch master cyl. On the clutch mast. cyl. look for wetness on it's bottom side and on fittings, also look for wetness on the pushrod coming from the clutch pedal to where it enters the rear of the cyl. Also look for a fluid trail on the floorboard under the floor mat. If no Leak is found and you get a good solid stream of fluid from the slave cyl when bleeding it. Drop the tranny again and replace the slave cyl. If there is no leaks found and you cannot get a good solid stream of fluid when bleeding the slave cyl , look for dirt or debris stopping up the bottom of the fluid reservoir, if it looks good and clean then replace clutch master cylinder.

Another possibility, especially if you had a rough time getting the tranny and the bell housing to mate up, drop the tranny again and check to see if the pilot bearing ( in the back of the engine crankshaft) was damaged during insallation. You can do this by visually looking for burrs or bent edges on it (signs of it being crushed) and by inserting your clutch alignment tool into it and verifying that it seats fully into it and turns freely. If the pilot bearing bites into the inputshaft of the transmission it will literally lock the transmission straight to the crankshaft and render a perfectly good clutch system uneffective. Good Luck

If the clutch arm is moving when you depress the clutch pedal then the problem lies elsewhere, stop bleeding it.Chances are you nicked the pilot bearing or it was on its way out, try starting the vehicle in gear and driving it in that gear, it may /may not resolve the issue, did you pack the pilot bushing full of grease before the installation.. ?, if so you may have forced the bushing out of the crankshaft..it good practice to replace the bushing anytime its open for service.
