hill holder & clutch cable, pedal adjust

Looking at L Series style hill holder the return spring on the hill holder looks to serve as a clutch pedal return spring as they do not have such thing between top of clutch fork forward to engine as fitted to non hill holder vehicles.
The level alignment of clutch pedal across the two pedals - brake and clutch is all up to the cable adjusters under bonnet at the fork.
Is the adjust at the cable really only for pedal look and feel, not as wear occurs at clutch?
With a clutch of unknown condition I felt cable was slack and wound it in 8mm or so without checking pedal height before then pull engine.Have just fitted a new clutch/machined flywheel to find cable still looked slack, adjusted more then to find pedal sits too high - so the only adjust for clutch pedal is in the cable isn't it? ngine stay bracket also comes into play here too at times?
I refitted hill holder against my better judgement. If I bypassed it would mean fitting a return spring between fork and bell housing - at present it looks like I will now also have to fit secondary return spring here for some reason, as hill holder spring not doin' the job I expected.
Who knows and loves hill holders??

I have a manual tranny on a 93 L Series.
I actually need to replace my clutch cable,
as it makes a pinging noise sometimes after I release it. (frayed wires grabbing the case?)
I have no complaints about pedal return tension.
I'm assuming my L Series has hill holder... does it?

I don't think I've ever driven a manual transmission old enough it didn't have hill holder, in hilly conditions that is.
Thanks to your post, I will pay closer attention to my pedals,
as I'd prefer to have the clutch stay at the same height and return tension once I replace it.

hill holders use a cable from clutch fork around to a hydraulic unit (the hill holder) bolted to LHS chassis rail

I love my hill holder. I probably don't know it so well but this is how it works for me.
With the clutch pedal pressed to the floor the hill holder will hold what ever braking pressure you put into the brake pedal, once released the brake pedal the hill holder will hold the vehicle via the clutch pedal so long as the pressure set from the use of the brake pedal is enough to hold the subi on that slope. Best bit is that it gets rid of the handbrake start if you know your subi well enough.
From what I understand the hill holder either uses the front brakes only or one side of the twin braking system - this is the system where there are two separate systems in place so that if one brake line gives out you don't lose all braking ability. One front wheel is paired to the diagonal rear wheel in this setup. I think it uses one side of the twin system, you'll feel the car move a little when you take your foot off the brake pedal initially. Clutch must be held at the floor and not moved.

I'm pretty sure that the subarus are the first to use the hill holder and BMW have taken it up recently too. Brilliant idea IMO.
Jonno - I don't think the hill holder spring is designed to be used as the spring return - the more you wind up the nut on the hill holder cable the further up the top of the clutch pedal movement is where it will engage, and then possibly restrict the amount of movement in the clutch pedal to the floor.
My clutch was set so that the hill holder is effective just a little bit below where the clutch bites so that when you use it on a hill you don't bog down trying to catch the vehicle as it starts to roll backwards - you want it smooth from the standing start without rollback
Yank: It might take some figuring out where you want the initial bite of the clutch to be with the new cable - it's just in the adjustment. I'm not sure of the noise you're talking about, but I doubt a frayed cable will make that noise, mine certainly didn't and it was a heavy mofo by the time I replaced it!
Hope this helps
Cheers

How do I feel when my hill holder starts to work?
I have no experience without a hill holder, on hills.
My clutch has always been on the heavy side. Something I'm unimpressed with. Hopefully the new cable will make it easy, like my 08 Civic, which happened to be as light and springy as my employers Triton ute and Holden Combo.

heavy clutch can be in cable or like an EA81 style clutch, the fork digging into the release bearing carrier which was cast iron unlike our EA82 stuff.
I'll have a tinker for sure.Maybe add a Jonno spring and actually learn how to use this feature

A Jonno spring will make the L Series clutch cable feel like a modern clutch cable?
