How do I fix my clutch pedal

either the master clutch cylinder is bad or the slave cylinder is bad. The slave cylinder is difficult to bleed. You should use a mityvac to bleed system.. it will require 2 people and new fluid. never let master cylinder to get low on fluid.

The problem is that there is still air in the system. You will need a friend to pump the cylinder while you work the bleed screw. You may have to loosen the line at the master cylinder to allow the cylinder to prime up . But what ever you still have air in the system

Only if it has a leak somewhere. Not that many places to check. Sometimes the master will leak, and you will have brake fluid below the clutch pedal.
A single steel line runs from master to the slave cylinder, down on the transmission bell housing. Check the line and the slave cylinder for leaks. If the slave is leaking, probably need a new one. And same for the master cylinder.
Fill the reservoir and check clutch operation. If any air got in the line to the slave, you will have to bleed the slave at the bleeder valve there. They are bled just like brakes, using the clutch pedal.

Gravity will not bleed the system as you need pressure in the master cylinder to bleed out the air. Once you have pressure bled the system you will have a good clutch

The air needs to be bled out of system. Should have a "bleeder" on the slave cylinder resevoir. Fill 1st and open bleeder screw. Have someone push clutch pedal down and close bleeder when pedal is fully depressed. Do not pump pedal. Repeat until a steady stream of fluid is achieved. REMEMBER TO WATCH RESEVOIR LEVEL AND KEEP FULL DURING THIS PROCESS!!!! Top off when finished bleeding. This should fix your issue.

Your solution is a replacement of the master clutch cylinder and the slave cylinder

your clutch master cylinder is right beside your brake master cylinder. I would advise you to replace the master cylinder and the slave cylinder together. The slave cylinder is on the side of the transmission. The slave cylinder does have a bleeder screw on it after the parts are bolted in place fill with dot 3 brake fluid and open the bleeder on the slave cylinder until fluid starts dripping out. Then tighten bleeder then open bleeder and have someone push down on clutch pedal while the pedal is pushed down tighten the bleeder the release pedal. Repeat this procedure until you get no air and the pedal feels normal and you should be good to go. Good luck!

bleed master cylinder first then slave

Hi:
If you have bled the system, you are down to either having a bad clutch master cylinder, or a bad clutch slave cylinder. You could eliminate the slave cylinder by removing the line and capping it off, and if you have a firm pressure on the clutch pedal ( don;'t try to push it down, just check for pressure!) then your slave cylinder is bad. If you cap off the line, and bleed the system, and the pedal still has no pressure, then your clutch master cylinder is bad!

If you've not done anything to your truck, check the Clutch master cylinder under the hood, there is a resivoir that should have brake fluid in it. It usually sits next to the Brake master cylinder & is a smaller unit. If nothing has been done to the system recently, and your fluid is full, either the Clutch Master Cyl. or the Clutch Slave Cy. mounted on the bellhousing of the trans. is defective, or has a leaking connection.

If leaking connection, tighten & bleed the system. Check under the clutch pedal on the floorboard for brake fluid, if you find it, the Clutch Master Cyl is the problem & will need ot be replaced. Otherwise, the Clutch Slave Cyl. will need to be replaced. System has to be bled after replacing either & the Clutch Master Cyl. must be bled before hooking up the lines to the Clutch Slave Cyl.

Good Luck

good luck.
