2004 Honda Element...the clutch pedal engaging at 50%

I assume that means that the clutch does not engage/disengage when you press and release the pedal. There are a number of possible issues here. First, does the pedal feel "soft"? Is it easier to press down that usual? If so, the problem may likely be in the hydraulics of the clutch. A bad master or slave cylinder will not allow hydraulic pressure necessary to engage/disengage the clutch.
If the pedal feels normal, then the problem is most likely internal to the clutch mechanism. A bad release bearing or a stripped clutch disc are the most likely culprits for this issue.

Clutch plate and pressure plate seem to be too weak to pull the car. To test the clutch plate, park the car on flat surface. Pull the hand brake up, start the car, depress the foot brake pedal, depress the clutch pedal, put the car in 1st gear, press the gas pedal and leave the clutch pedal at once, while keeping the brake pedal depressed.
Follow one of the two following statements:
1. Engine does not shut down and remain start. (Clutch plate, pressure plate and clutch bearing defective - Replace all as a set)
2. Engine shuts down. (Clutch system is OK and does not require any repair).

You have a leaking master or slave hydraulic clutch cylinder. I recommend you replace both

I had this same problem the cable is fine its a clip on outer cable to stop it mooving when you press clutch mine poped when I tightened the clutch cable still don't have solution though waiting to payday to take it to garage

you have 4 cyl or V6 engine, how much free play you have on clutch pedal (take your hand press clutch in untill gets harder to push in) should only have about 1" free play, and also when you release clutch while in gear should start engaging about 1 1/2" up when releasing

How is it suppose to ? What is 2 ?Does the clutch engages right away when you release the pedal or almost at the end (pedal up), did you check the freeplay on the pedal ? Should have free play, push clutch pedal by hand and you should move it a half inch before feeling resistance.

Clutch pressure plate weak.Replace the whole clutch assembely.Hope this was helpfull.

you need to bleed the clutch system.. have someone pump the clutch pedal three or four times, hold it down and release the bleeder valve( make sure the person holds the pedal down till after you tighten the bleeder valve back down) repeat this four or five times or till the clutch pedal feels like it did before.. good luck keith...

have u checked the slave cylinder? should be inderneath the drivers side door

check the fluid level first, if its empty this will happen, if so full it and bleed the clutch, if not it could be the slave cylinder and failing both, it could be the clutch itself, easiest way to check is to see on the gearbox if the clutch is engaging when you press the pedal down.
just ask if you need more help
