I installed my clutch this week and last night I went to adjust the pedal only to find out that the X has a non-adjustable clutch pedal. What were they thinking?? The pedal engagement on this new clutch is really high....at the top of the throw and it is REALLY annoying.

I do have a couple concerns about this:
1. As the disk wears, the pedal moves up and you adjust accordingly. Looks like on the X we will just be putting new disks in as it wears.
2. Engagement is harsh during normal slow city driving....not because of the stiffer clutch but because at the top of the throw your foot is no longer near the ground and it is in an unnatural position. You can feel the hard engagement on your drivetrain just driving normal. I suppose I will get used to this and adjust my driving. When I'm hogging on it...is shifts great and engagement feels smooth.
3. My tranny has been 100% butter. I have been suprised to read about people having 2nd gear synchro problems because my experience has been nothing but flawless. Now I can feel the notchy feeling. Again....irritating.
4. I'm worried about over-extending the pressure plate. You are supposed to have 3/8" of travel to the pedal stop PAST the disengagement point.

Has anyone else experienced the high pedal engagement?? Is there any way to adjust the pedal engagement??

 

Yes, this clutch engages very high on the release. While different, I wonder if ACT's clutch differs from OEM and is adjustable?

Later, Ken

 

This is something I reported months back. There is no adjustment.

The aftermarket (ACT, RPS, Exedy) need to make an aftermarket Master cylinder.

I've also heard of the master cylinder's breaking due to increased pedal pressure.

Again, ACT, RPS and Exedy if uour listening, something needs to be done...Imagine how little sales you'll get due to broken Clutch MC's!!

 

No it is the actual pedal in the car that is not adjustable. Engagement was fine with the factory clutch, but now with this aftermarket clutch it is pretty miserable to drive and the over-extension from pushing it all the way to the floor will be bad on the pressure plate.

My ACT in my VIII was the same, but that was quickly resolved with an adjustment of the pedal. Pretty normal.

 

Well, I don't understand one thing: the stock pedal engages pretty high to me already but nothing outrageous. Most clutches that I've driven usually engage about half way through the pedal travel, so how is 3/8" of travel from the engagement point to pedal stop normal???? That would mean that most clutches engage almost immediately when you let them up from the pedal stop and that's never been the case with any clutch I've ever encountered. There should always be at least 2 inches of travel from pedal stop to the engagement point because you can get lockout when trying to shift if the clutch isn't able to go past the engagement point a bit. I think you might be a little confused on this one, but maybe I am misunderstanding what you are saying. In any case I agree that it's strange that the clutch pedal in the X isn't adjustable. I have yet to figure out why they did that.

 

I'm not sure about single disk clutches like this, but when we set our multi-disk clutches up on our race cars here is the prodecure.
-Jack the car up in the air and put it in 4th gear.
-Have someone put tension on the tire by turning it by hand. Have a second person press the clutch slowly and wherever the clutch disengages, 3/8-1/4" past that is where you put the pedal stop.

This is how Tilton and Quarter Master have us setup all of our clutches. On NA cars we use a small twin metallic or carbon and on our turbo cars we use Tilton triple carbons.

On a twin or triple plate clutch if you overextend the pressure plate you can actually reengage the clutch AND ruin the pressure plate. I'm not sure about these single disk clutches, but I know right now I have to be overextending this pressure plate. If you think your stock clutch engages high, you would hate this one. It works and I'm getting used to it. I just think Mitsu pulled another brilliant move on a performance car where they KNOW people have to replace that POS stock Exedy with something that will hold even the stock power. Non adjustable pedal??? Common.

 

Maybe ACT Man can give some advice. I had great luck with my ACT on my VIII holding stupid amounts of torque and preserving my transfer case

 

Interesting, although I'm confused about one thing though; how could overextending the pressure plate reengage the clutch disk? If the pressure plate is pulled away from the disk when the clutch pedal is depressed then the further the pedal is pushed the further the separation would be between the pressure plate and the clutch disk. I can see how overextending the pressure plate could damage the diaphragm, but I can't understand how a reengagement could occur. Could you explain how this would happen? I'm very curious about this now. Thanks.

 

This is good to know as I just ordered my ACT last week, I need to replace the clutch and since I don't know how, I have to take it to the shop

 

This sucks because i was getting an ACT or exedy tomorrow. Now i will have to wait or get OEM again

 

I wouldn't shy away from a certain clutch because of this, I was just asking if people have a solution for adjusting the pedal. I have gotten used to it and it isn't too bad at all.


STi2evoX - I couldn't give you a good explanation because I don't know. I'm just telling you how they have us set them up as to not overextend the PP. This pull style PP might be totally different. Maybe call Tilton and ask them for an explanation (805) 688-2353.

 

We have not experienced this , you may what to try removing the pill in the slave and bleed it well .

 

I will give that a shot. Did you guys remove the restrictor pill? I'm not having ANY issue with disengagement...it shifts beautifully now.

 

im having a lot of problems with xtreme pressure plate from act im on my 4th master cylinder
