55 reg honda accord clutch problem or slave or cylinder problem

possible failure is the clutch cable or clutch master cylinder ( which ever you have )
if it is a cable the cable wears and strands of the cable jam in the case stopping the clutch pressure plate from engaging
if hydraulic the compensating post in the master cylinder becomes blocked and does not release the pressure to the clutch slave cylinder
The fix will be to replace which ever you have

Check to make sure you placed the clutch plates correctly.

I really need more info such as...Mileage,did you do the job yourself,if so was the slave cylinder and or clutch master cylinder changed and did you bleed the system..?...So I will explain without knowing,,...Before a clutch wears completely out we find ourselves constantly working the clutch pedal stressing all clutch system components..In most cases I have looked closely and found slave cylinder and clutch master cylinder leaking ..however the slave cylinder can wear out without leaking..Most importantly the fluid itself wears out every 15 to 20,000 miles.. You don't notice but the fluid gets thousands of tiny air bubbles in it and makes the clutch weak and spongy..(Same with brakes)..You should always bleed system with an assistant just as you would a brake system..,This alone will cause the problem you are experiencing...If you already know that and you have bled the clutch system then you know the slave cylinder is at fault..(UNLESS THERE WAS SOME TYPE OF MISALIGNMENT WITH RELEASE BEARING....YOU SHOULD ALWAYS CHANGE RELEASE BEARING WITH FORK WHEN DOING A CLUTCH SERVICE..)...I assume you did...I would inspect for leaks..,Bleed it again if no leaks...If that don't help and no leaks are found change slave cylinder and or master cylinder.....I hope this helps........Brooks/Metalpoet.......

If you mean you step on the clutch, put transmission in gear and release clutch with no engagement (pedal returns to top position) there is a good chance your clutch disc or pressure plate, or both are worn out and need replacing.
If your clutch pedal is going to the floor and not returning there could be a leak in the system, a bad clutch master cylinder or a bad slave cylinder on the transmission. Check the fluid level in the clutch master cylinder. If it is low or empty you have a leak or component failure. Visually inspect clutch master, line, slave cylinder for fluid leaks. replace as needed. If hydraulics are o.k., suspect clutch disc/pressure plate.

Check and bleed out the air in the system . It may be necessary to undo the line on the master cylinder to allow the unit to prime up first . Do up the line then bleed from the slave cylinder nipple. You will require a helper as it will not bleed out by gravity.

check the hydraulic clutch is releasing /engaging the clutch plate. Replace the clutch master cylinder if there is no clearance at the clutch slave cylinder piston rod. If cable clutch replace the cable as it is not allowing the clutch to engage.

If it is a hydraulic clutch, and not cable operated, there will be two cylinders. A clutch master cylinder will be mounted on the firewall next to the brake master cylinder. One steel line will go from the master cylinder down to the slave cylinder bolted onto the transmission housing where the clutch lever extends out of the housing. Other than bleeding the slave cylinder, no adjustments are necessary on hydraulic clutches. Cable operated clutches have an adjusting mechanism to take up slack when the clutch disc wears. The adjuster will be inside the engine bay.

you could have a broken disc in the pressure plate which wont let the clutch plate disengage properly

These cars use a Hydraulic system for their clutches. chances are if your pedal is low it is time for a new clutch providing your slave cylinder is ok. With this system you will have a master cylinder for the clutch and a slave cylinder which moves the clutch itself when push the pedal. you need to make sure their is no leaks in these two parts.

I hope this helps, Allen

the clutch master cylinder and slave cylinder are bad relace them starting with the slave cylinder first
