Roger K Posted May 26, 2021 Report Share Posted May 26, 2021 Should the clutch pedal have a return spring inside the car, like the brake and accelerator have? Mine didn't have one, but I think the parts book shows one. Link to comment Share on other sites More sharing options...
Mathew Posted May 26, 2021 Report Share Posted May 26, 2021 Off the top of my head without looking at my spares or car i would say yes. Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 26, 2021 Report Share Posted May 26, 2021 definitley needs a spring on clutch and brake pedals https://www.canleyclassics.com/?catalogue=triumph-gt6-mkiii&diagram=triumph-gt6-mkiii-clutch-pedal Link to comment Share on other sites More sharing options...
Roger K Posted May 26, 2021 Author Report Share Posted May 26, 2021 Thanks, I'll add one. Is there a setting for the adjustable pushrod on the clutch master cylinder? I can't find any mention of how to set it in the workshop manual. Link to comment Share on other sites More sharing options...
johny Posted May 27, 2021 Report Share Posted May 27, 2021 I dont think as standard the pushrod is adjustable, mine certainly isnt... Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 27, 2021 Report Share Posted May 27, 2021 agree its a fixed length as standard .....unless someones fitted an adjustable one do check the pedal shaft is not seizing on both pedals its important that both C & B pedals fully return and give a small rattle fit endfloat to the push rod or the master cyls wont recuperate properly ( easy to finger a check under the bulkhead gaitors ) Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted May 27, 2021 Report Share Posted May 27, 2021 I bought two replacement springs for the Herald pedals a few months ago, they were rubbish. Too long, so no real tension, and they didn't help the pedal return. I ended up fitting a pair of old ones that were much better. Link to comment Share on other sites More sharing options...
Roger K Posted May 27, 2021 Author Report Share Posted May 27, 2021 That's interesting - the old pushrod was an adjustable one, which had been (badly) welded solid at some time. The new cylinder I bought is a genuine Girling one which came with an adjustable pushrod ready fixed, of the correct length. I guess I just adjust it to get the pedals level, just off moving the pushrod. The new springs from Canley are fine, same shape as the old but actually a bit stronger (maybe just newer).

johny Posted May 27, 2021 Report Share Posted May 27, 2021 As Pete says whatever you do the pushrod mustnt be under pressure after any adjustment. In other words you must ensure it can still be rotated easily and freely with your fingers before you put the rubber cover back on... Link to comment Share on other sites More sharing options...
Roger K Posted May 27, 2021 Author Report Share Posted May 27, 2021 I may not have been clear enough - I have an adjustable master cylinder pushrod, the clutch slave cylinder pushrod is fixed. I can't rotate the adjustable master cyl pushrod as it has a clevis fork to the pedal. So, the advice is to set the length of the master cylinder pushrod to just before the slave cylinder pushrod goes tight - i.e. can still be rotated easily? The master cyl piston may be slightly compressed to achieve this. Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 27, 2021 Report Share Posted May 27, 2021 if you compress the master cyl you leave the reservoir port open thats asking for low pedals the whole idea is the reservoir refills the system with foot off so a small free play/end float of the pushrod is essential or the tail seal that has to block the reservoir as soon as you apply pressure will supply the reservoir not the brake circuit as the port is left open Pete Link to comment Share on other sites More sharing options...
Roger K Posted May 27, 2021 Author Report Share Posted May 27, 2021 Thanks - so I want just a little bit of play at the pedal to master cyl clevis, so the master cyl is fully relaxed. Link to comment Share on other sites More sharing options...
johny Posted May 27, 2021 Report Share Posted May 27, 2021 sorry rotated wasnt the right word, I meant rocked. Anyway, as you say, anything but just ensure the pushrod isnt under pressure... Link to comment Share on other sites More sharing options...
