Clutch Fluid

Yesterday, the pedal started squeaking with a quick creak when I put the clutch in. I can't tell if it might just be the pedal itself, or the cylinder. Just can't nail down the source.

But I opened up the cap to the reservoir and looked around for leaks and noticed that the fluid is pretty dark. There are about 12k miles on this clutch, almost all parts are new.

The clutch has always felt a bit stiff to me, but I've got nothing to compare it to in order to know what that even means. Others have driven it. One guy initially said, "Oh, your clutch feels... well... never mind, seems fine." But that's about it.

So should I.... Could I.... What might I do?

My 300 Tdi 110 had an LT77 and the clutch was super stiff. My leg would feel like jello if I got stuck in city traffic.

My pedal has done the same, lubed up the pivot point and all was right again. I also have a very heavy clutch pedal, I think due to the HD clutch I installed. You mention the fluid is dark, check this out if you haven't already...super nice upgrade.

I'm thinking of siphoning out the fluid, replacing with new, then watching to see how long it takes to cloud up again. That SDO kit may be in my near future.
 
This is on my project list. LOF has on their website:
1. Does the POWERspring fit my DEFENDER?
The LOF POWERspring will fit Defender models 300TDI, TD5 and also TDCI PUMA vehicles.
In order to double check that it will fit, simply take a look at your clutch pedal:
  • If the clutch pedal arm is a flat sheet of steel in terms of profile – IT FITS!
  • If the clutch pedal arm is a U shaped formed steel profile, unfortunately it wont fit, but there is a solution! Simply remove the older 200TDI style pedal box (6 bolts in the footwell) and refit with the later style pedal box – Part number SKB500280 (sold separately)
So I would need https://www.lrdirect.com/SKB500280-Pedal-Clutch/ and https://lofclutches.com/shop/td5/l-o-f-powerspring-pedal-assister-kit/?v=7516fd43adaa

Not sure what this powerspring thingy is, but fit a TD5 clutch unit I found it a big improvement. I was going to go with a Red Booster as I have a dodgy left leg but the newer unit is great.

From what I gather, the powerspring sold by LOF is a stronger spring than what comes on the TD5 clutch pedal. So it reduces the pedal effort even further.

I think it’s the exact opposite, it’s a weaker spring thereby reducing effort. The LOF one only has two winds, stock has three. Seems like the spring would resist the push and spring the pedal back to the up position. I’ve been trying to think my way through this one.

No stronger. The newer style clutch boxes use an over center spring. It pushes down in the down position and up in the up position.

Personally, I've tried the change and found it did not do a lot other than make the clutch feel less linear. I have not tried this heavier spring though. I see they want insane shipping money.

The other problem with the new clutch pedal boxes is that they eliminated the adjustable up stop and rely of the master rod to hold the pedal height in tension. It is a bad design, IMO. I added an up stop to my pedal box.
