I think I have some parts missing from my 2006 OEM pedal box, clutch linkage. It just drops right to the floor and doesn't return. I don't have it plumbed yet.

What's missing? Installed incorrectly?

Does it feel like it 'overcams'? If so, the 3 assemblies I've worked on do the same thing. When they were in the donor car they worked fine. I think the master cylinder with fluid will be enough to spring it back. I think Subaru did this to help give the clutch pedal a pleasing feel and make it easier to hold the pedal to the floor at stoplights.
Reach down and pull the pedal back up and it will 'flip' back to its normal position.

I just pulled mine last night and noticed the same thing. What matteo said about it being "cammed". With the cluster in the car, as soon as I removed the clutch cylinder and pushed the clutch pedal down, it just went to the floor and stuck there. I believe I could pull it back up manually and raise it to the disengaged spot and it would stay there, but move it half and inch forward and it would slam all the way down.

I thought I might be missing a spring (pink arrow) and/or a stop (red arrow).

Normal Subaru clutch operation will work fine after installation and proper bleeding lots of posts about it on all the subie sites

I'll look at my pedal cluster when I get home in a couple hours and see if it looks any different from yours. Will post back then.

Ya, this is identical to what I experienced. My wife pushed the clutch in (before plumbing) and scared her when it loudly popped to the firewall, lol. She thought she broke something. Once plumbed and partially bled, everything worked fine.

Until it is bled that's what it does. the spring assist will hold it down and up. once you go over center.

BTW, it's the clutch diaphragm spring that pushes the pedal back up. That's why it doesn't work until it's bled. Mine took a really long time to bleed, but works great after.

Mine looks the same Rasmus. The pedal should stay all the way up if you move it there, and should stay all the way down if you move it a little past.

Perfect! That picture and description helps big time. Looks like I'm missing the little black stop but the rest of it's all there.
Thanks everyone.

Just re-installed mine last night to correct the brake master cylinder "tilt" and mine is the same as yours.
I expect it will be good with full fluid and bleeding.

I can confirm it will work fine once bled.

I dented my firewall. I pushed my pedal and "bam!" it slammed the wall. Oops.

When fully depressed, mine hits the rubber stopper at the same time as the firewall.
On another note, Rasmus you are going to get to the gas pedal soon. I just mocked mine up in position. Its an 02 pedal. When fully depressed it hits the shaft for the clutch master cylinder actuator. The resulting travel of the top of the pedal is only about 1.5 inches. Is this enough? I measured my throttle and it seems a bit more at full throttle.

Mine did that when I used the provided mount, but it was enough travel to get to full throttle. You are going to want to seriously think about making an alternate mount, the provided one puts the cable end at an angle.

Mount the pedal directly to the firewall, you may want to reinforce it
There will be plenty of travel if you do it this way, I have an 05 with cable throttle, many of us did it this way, details in my thread

Thanks RM. I mounted it directly to the firewall like you said and used the FFR bracket as reinforcement. i riveted the top of the subaru pedal mount to the FFR bracket then bolted to the firewall, and added a couple extra rivets to the front of the firewall in that area for more reinforcement.
I have pics in my thread. Harley818

Has anyone made a pedal stop for the DWB pedal?
Without one the ECU puts the car in limp mode if you push the pedal to far.
Please post a picture. I need to do it before autocross this weekend.

I don't recall having any issues with mine going into limp mode?

It might be ECU software specific.
I have a 04 FXT MT ECU.
Maybe you gas pedal hits something before it get to 85%.

Ahhh. Mine is from an '06 WRX. Definitely doesn't physically hit anything before 100% (only the built-in stopping point). I'm fairly delicate with the throttle input.

Tomarrow, I'll try key on, engine off, pedal to the floor, and see what CEL code happens.

On my 06 WRX running gear- I have floored it many times without it going into limp mode. For a throttle stop, I'm going to rivnut 1.5" flat iron at an angle to the firewall supports then use a long bolt with nuts on each side to adjust. I know while racing, pushing harder on the pedal makes you go faster :\ I dont want to break it.

I added my pedal stop tonight. I'll add a picture soon.
The way it was working. The OBDii throttle position monitor would slowly rise as I pushed the pedal. When it reached 78% it would stop rising even I continued to push the pedal. When I was about 1" Past the point where it stopped rising. The dbw throttle body would kick off and the CEL would come on with a P2128 fault. With that fault the throttle would not work. Until you reset the code or cycled battery power on the ECU.
I set my throttle stop at 1/2 between rising and fault.
