Manual clutch clutch pedal sticks after shifting and depresses to the floor

A clutch pedal normally does go all the way to the floor. If you can shift gear without a crunch, it is disengaging OK.

The loss of power could mean the clutch plate is worn and is slipping when engaged. There is a crude test for this. Start the engine and idle it. Apply the footbrake firmly, depress the clutch and put the gearbox in 3rd. Let the clutch out slowly. If the engine does not immediately stall, the clutch needs replacing.

on what , you have to be specific most cars are the same all stick shift cars have it on the clutch pedal and must be depressed to the floor completly before it will work , if it is an auto play around with the shifter , should work

It happen twice to me ,spring come out from clutch disk and jam the pressure plate, check transmission shift very well with engine stopped, When you push the pedal you push the spring and put pressure on the disk

There is a safety switch on the clutch pedal-it is called a clutch interlock switch. Unless the clutch is depressed (so the switch is on), the power won't pass from the key switch to the starter to start the car. Check your clutch safety switch. It will be up high on the pedal, or mounted close to the pedal so the pedal operation will actuate the switch. It may be defective, or it may have slipped out of position.

slave cycinder! our check clutch fluid

The pedal return spring should be checked. Also the pedal bushings where pedal connects to the pedal support up under dash may be worn and not allowing free pedal movement. Work the pedal with your hand and watch the upper mounting of the pedal to see if you can see the problem. I would expect the bushings need replaced. You might try a little light oil where the clutch pedal attaches.

must be stopped, brake pedal depressed and clutch pedal depressed, check your owners manual

your clutch uses a hydraulic master and slave cylinder to disengage. It is likely that the slave has been leaking and the reservoir gone dry, thus allowing air into the system and reducing effectiveness. Check the clutch master cylinder reservoir (near the brake reservoir) fluid level. If low, also check the slave cylinder at the clutch for leakage. If leaking, replace the slave and bleed the system. If you need procedures or have more questions, please let us know.

I believe your pressure plate is broken and at a minimum will have to be replaced along with the clutch disk.

there is a way to pressure bleed the system. depress and lock the clutch pedal down with the use of a pedal depresser or a stick, long extension something, with the pedal depressed crack the bleeder open and the pressure plate springs should force fluid out of the bleeder. note in some cases the pedal will stick in the depressed position. without the springs from the pressure plate. this is normal. just manually return the pedal to its start position, and repeat until air is purged.
