hurlbird Posted June 13, 2022 Report Share Posted June 13, 2022 My elderly father-in-law is looking for a clutch solution that makes pressing easier. He wants to still drive but the clutch is a bit hard for him. Any ideas? thanks Quote Link to post Share on other sites

DaveB66 Posted June 13, 2022 Report Share Posted June 13, 2022 (edited) +1. When I bought my TR4 it had a remote servo for the clutch for precisely the reasons you state, The servo was mounted on the nearside bulkhead, with the washer bottle moved, photo attached.

Waldi Posted June 13, 2022 Report Share Posted June 13, 2022 There are other aspects that can be done too, like a Laycock clutch (expensive), change of cylinder diameter, ensuring all picot points are not worn our and lubricated, but the servo-route is probably the easiest.

JochemsTR Posted June 13, 2022 Report Share Posted June 13, 2022 (edited) or try this: -0,70" Master, -Sachs Clutch (not Laycock) -concentric slave cylinder I can press my clutch by hand. Edited June 13, 2022 by JochemsTR Quote Link to post Share on other sites

Waldi Posted June 13, 2022 Report Share Posted June 13, 2022 I have not done it myself (my clutch works “light” too after a careful full rebuild with reconditioned cylinders (Past Parts), new clutch shaft, pins, etc.) but think the servo-solution is easiest (least intrusive) and has been done successfully by others. Here is a link to an old post: Cheers and Gruesse, Waldi Quote Link to post Share on other sites
Andy Moltu Posted June 13, 2022 Report Share Posted June 13, 2022 There are readily available cheap aftermarket remote servo's out there for the TR4/4a brakes which can easily be plumbed into the clutch hydraulics. (literally a couple of pipes) and you can T into the brake sevo vacuum line. If you don't like it then you can remove it. eg One like this Quote Link to post Share on other sites
FatJon Posted June 13, 2022 Report Share Posted June 13, 2022 Seen the clutch servo done a few times before for the same reason. It works very well and any competent mechanic can install it. A few nuts and bolts and a bit of brake line. And of course there's a perfect location for it tight where the brake servo would be if the car was LHD. Quote Link to post Share on other sites
JochemsTR Posted June 13, 2022 Report Share Posted June 13, 2022 I am confused. I thought this was about a TR6. How can a servo be installed with a brake servo already in place? Quote Link to post Share on other sites

JochemsTR Posted June 13, 2022 Report Share Posted June 13, 2022 Yes, I would expect so, but maybe someone can share some pics on a TR6. The pedal needs to press in some kind of Master. Then a connection from the master to the Servo, which has another Master2. Then a connection from Master2 to the slave. Right? Quote Link to post Share on other sites

No its a remote servo so its just inserted into the clutch slave feed pipe. A "T" would then be inserted into the vacuum supply pipe as well. Like this on a 6 Stuart.

Andy Moltu Posted June 13, 2022 Report Share Posted June 13, 2022 A remote servo is sriggered by the hydraulic pressure (rather than the pedal pressure on the TR6 brakes). The remote servo has a hydraulic cylinder that receives pressure from the clutch pedal being pressed via the pipe that runs across the bulkhead and the diaphragm in the servo puts pressure on the output side. Effectively can be mounted almost anywhere but usually on a RH drive UK car roughly where the one in Stuarts picture is as it gives the simplest routing for the pipework.

harlequin Posted June 13, 2022 Report Share Posted June 13, 2022 A modification to cars used by people with leg problems is a duck clutch https://adaptivevehicleconversions.co.uk/general-adaptions/duck-clutch.html this uses a programed electric motor operated by a trigger on the gear stick.

Tim D. Posted June 14, 2022 Report Share Posted June 14, 2022 I reduced my clutch pressure by using a 0.625 inch master cylinder. You need to use an adjustable pedal pushrod and there needs to be low wear on the clutch components and the pedal is a little higher but works great. Tim Quote Link to post Share on other sites
Waldi Posted June 14, 2022 Report Share Posted June 14, 2022 Tim’s solution is probably the cheapest, so worth a try if budget plays a role but it will reduce the stroke from clutch lever situated at the side of the gear box. So make sure all wear is reduced as Tim says because that wear (play) will further reduce the effective stroke at the gear box clutch lever. Waldi Quote Link to post Share on other sites

In short - yes. However most modifications that add additional components give extra scope for things going wrong. Servo's are generally reliable as are brake and clutch hydraulics - if anything fails it is the slave cylinder because of dirt/debris damaging the bore/seals. Quote Link to post Share on other sites
hurlbird Posted June 19, 2022 Author Report Share Posted June 19, 2022 thanks all... can someone clearly describe the servo to me? thanks Quote Link to post Share on other sites
Z320 Posted June 20, 2022 Report Share Posted June 20, 2022 Easy is the 0.625“ master, several TRs run with this on my recommendation, some TR6 with adjustable push rod too Quote Link to post Share on other sites
hurlbird Posted October 11, 2022 Author Report Share Posted October 11, 2022 Stuart, how important is having the booster at the exact angle dictated by the kit bracket? i am in receipt of the kit i will install for my father in law. Quote Link to post Share on other sites

I wouldnt have said it was that critical as Ive seen them mounted all ways over the years. Heres another position. Stuart. Quote Link to post Share on other sites
