Clutch pedal has about 1/2 inch of play before engaging, from the floor. How can I adjust this?

check to see if you can adjust the clutch cable and make it a little tighter. they stretch over time. The amount of play is only a 1/2 inch or so. have someone sit inside and push the clutch peddle in and out and see where it starts to move. Loosen the locking nuts and adjust thread play till the peddle engages about a inch or two from the top. Not near the floor. It is not hard to do when you look at it closely.

The clutch is not fully disengaging. Adjust the clutch cable to obtain a 1/2 inch of free play at the top of pedal stroke. If clutch adjustment is not correct, damage to synchronizers or clutch release bearing will occur. Your clutch should begin to engage about an inch off the floor when releasing the clutch pedal.

The clutch is not adjustable it is fully hydraulic. That means it is self adjusting, if the clutch pedal engages high on the pedal and the clutch is hard to push you need a new clutch plate and pressure plate.

engaging?
you meant dis-engage im sure.
pedal up is engaged,
pedal at floor dis-engages it.
my guess, is the clutch drags unless i push the clutch pedal 100%
to the floor.
1: bad cable is 90% cause. non last this long.
2: no free play is way too loose.
3: broken lever on the pedal top. caused by #1

all fail modes covered here.

Your pedal height may be adjustable by a stopper bolt at top of pedal. You would have to check the specification for your car. Most important that the pedal has about a half inch free travel before clutch begins to engage. You need that free play to ensure the release bearing (the throw-out bearing) is not touching the fingers on the pressure plate when not engaged. If it always is touching, it will be rolling around constantly and will go out prematurely.
Your new clutch will allow gear engagement sooner as the clutch pedal is released. I mean gears will engage just as pedal is lifting off from floor. You should notice that difference-the old clutch would have taken longer pedal travel from floor before releasing.

not sure if theses have adjustment on them but if so it will be under the dash on the clutch rod its self

Clutch ADJUSTMENTS 1997-98 Models CLUTCH PEDAL HEIGHT The clutch pedal height should not be a periodic adjustment but may be checked after components of the mechanical clutch system have been replaced. The proper clutch pedal height should be 0.2 in. (5mm) above the brake pedal height If adjustment is necessary, loosen the locknut and turn the adjusting bolt until the appropriate height is reached. Once set, keep the bolt from turning and tighten the locknut to secure the adjustment. CLUTCH PEDAL FREE-PLAY The clutch pedal free-play should be checked from time-to-time in order to assure proper clutch operation. The proper clutch free-play should be 0.6-1.1 in. (15-25mm). Fig. 1: Pedal free-play is adjusted at the joint nut (2), while keeping the outer cable nuts (3) tightened around the center cable thread portion

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. If the free-play must be adjusted, turn the joint nut (2) located at the transmission end of the clutch cable in or out, as necessary to achieve the proper play.
3. Once the correct pedal free-play is obtained, check the free-play on the release arm (c), it should be 0.02-0.06 in. (0.5-1.5mm).

1999-01 Models These vehicles are equipped with a hydraulic clutch system. No adjustment is necessary.

In just about all vehicles you should have about 1/2 to 3/4 inch free-play before clutch begins to release. Adjustment is done this way , Not from the floor up...

You want to shorten the cable. Loosen the lock nut.Turn the cable adjuster clockwise to shorten the cable. This takes some skill, and knowledge to get the clutch adjusted just right. You want about 1/2 inch of free play in the pedal. All of this varies according to the wear on your clutch. You say your clutch is new, so acheving a proper adjustment should be no problem. Keep tweaking the adjustment to get it catching where you like it.

I assume it is a cable operated clutch. If so the adjustment is tightened so that there is about 1/2 to 1" of pedal travel to clutch operation, provided the gears can be selected smoothly.
