Clutch popping when engaging pedal & Car off -- SOLVED

What I'm also planning on doing is to revert back to the original clutch height and rotate the U-bracket instead of the small rod that goes into the master cylinder. I used my fingers to rotate the rod for adjustment, but now I am questioning myself if I should have rotated the U-bracket.

So, remove the cotter pin, and then you'll need vice grips or pliers to squeze the white cap to pull the pin itself out. At that point, the clutch will probably pop, either forward or backwards. It's on a huge spring, and is binary in nature - either fully engaged or fully not engaged. You can play with it a bit to see if you still hear the noise

I hope the solution is as simple as that. Once I get home at 5PM EST, I will try it out and let you know.

Sounds good. My clicking sound only occurs ~60% of the time I use the clutch, so I will play around with it for a good amount of time to see if I can replicate the sound between the pedal and the pin.

Great investigation going on here guys...does anyone have the link to this specific post in the thread / rationale behind it? I went through 10+ pages and I didn't find it...maybe I'm filtering for the wrong key words.

Cheers

I can't remember if this is the same information I read a couple of months ago, but here's one I found:

I just started getting the clicking too. I just assumed it was the helper spring (I'm at 8k miles. did adjustment at 7.5k

I genuinely think it has something to do with the rod going back and forth, instead of the bracket

OMG! I am not crazy. I have been hearing the clicking ever since I went over 7k on the odometer. I just thought I was clutching bad or something and have been trying all sorts of different levels to no luck. Really interested to see what you guys find out.

mine only clicks/pops at about about half an inch from the top, just after I begin to press the clutch. I can push it to the floor and pull almost all the way back then press it again and never hear it again till I let it out past that same point.

I did some additional troubleshooting last night and have found that my clutch does the same thing. It clicks when I press the clutch (about half-inch down) and it clicks again once I'm almost at the top (again, about half-inch down from resting point); I can't replicate the clicking noise as long as it's within that point.


trevorovert,
So I played around with the parts once I pulled out the pin (where the cotter pin is), and the noise is definitely coming from the master cylinder area/rod area. I played around with the clutch pedal (detached from the master cylinder rod) for a good few minutes, but I couldn't replicate the noise.

I spent 2 hours adjusting the rod and the U-bracket, and the clicking sound still exists (took me freaking 15 minutes to realize I can pull down on the rod to adjust the U-bracket... lol. I ended up rotating the rod at least 30+ revolutions after removing the speed sensor before I figured that out)

It's a bit softer when I drove it this morning, but that may be due to the cold temperature. (I remember last Wednesday, when Charlotte had snow, I didn't hear the clicking noise. That's when I wondered if ambient temperature had anything to do with the noise)

Man. I think tonight I may play with the clutch line.... see if I can isolate the issue as being between the master and slave cylinder, or as being in the master cylinder

Cool cool. Let us know how that goes.

Curious, doss the noise persist to the same degree of you clutch in and out very, very, very slowly?

If I'm understanding your question correctly, then yes. Whenever the clicking noise is made during clutch in, the same clicking noise will occur during clutch out.

However, there has been instances (for me at least), where the noise is made during clutch out when there was no noise during clutch in.
