95 Honda Accord EX clutch occasionally slips??

how do u mean will not bleed it? its probably the piston in the slave cylinder sticking. try using a vacuum bleeder. keep flushing with clean fluid until bled.

Not sure of the model EX, but it probably has a clutch hydraulic slave and master cylinder that has leaked out the hydraulic fluid. Fill the clutch master cylinder (near the brake master cylinder) with brake fluid and pump the clutch pedal several times. The clutch work again until the fluid leaks out, so the permanent fix is to replace the master and or slave cylinders and bleed the system. Other models have a clutch cable that would need replacing in this case

Check to make sure you placed the clutch plates correctly.

no fluid in the clutch reservoir due to a failed clutch slave cylinder
time to replace both the clutch slave and master cylinder

You need to replace the slave cylinder, it is contaminating the system fluid with rubber seal gunk, this is ruining the new masters. The clutch slave and master should always be done as a pair. This advice comes from 35 years of work experience.

problem is in the hydraulic clutch system
low fluid indicates a leak at the slave cylinder and not holding pressure indicates a leak at the slave cylinder or in the clutch master cylinder
If the master cylinder and slave cylinder have not been replace in side 5 years ago , the have them replace by a specialist brake and clutch shop
at this point there is nothing wrong with the clutch proper

check the slave and clutch master cylinder for leakage. look under the dash , at the clutch master) push rod attached to the clutch pedal) . try to see if there are any leaks around it. if so have it replaced and have the system bled to remove all fluid and air stuck in the system.

check the actual pedal and clutch linkage.  Also look for a fitting thats emitting air into the system.

I am totally unfamiliar with the particular setup you have, however I know a bit about clutches, Sifting through what you said, it appears that your clutch is set up too tight. By this I mean that the throwout bearing is always pressing on the release diaphram (or fingers) on the clutch cover. As you drive this is causing the clutch disc to overheat and slip. The repeated bleeding you are doing likely has no effect on this other than that the time you spend bleeding is allowing the clutch assembly to cool off. If the slave cylinder is part of the throwout bearing and is inside the bellhousing you need to remove it and get one that is slightly shorter. If the slave is mounted on the bellhousing and activates a clutch fork that moves the bearing you will need to find a means of backing off the slave adjustment so there is a bit of freeplay between it and the fork. likely since you can drive it you are looking at 1/4" or less play to get it right. My only concern would be that you may have overcentered the fingers on the pressure plate and damaged the return spring. slipping the clutch also has not done good things to the disc either. (like driving down the road with your foot on the brake is not good for brake pads)
Good luck with your project !!
