Smithfire67 Posted January 19 Report Share Posted January 19 Evening peeps Went to have a drive in my TR3 yesterday but did make it out of the shed. Absolutely no contact in the clutch even when let all the way out. As I'd had a problem last year with the slave mater cylinder I bled that again and that did allow the clutch to engage enough to roll out of the shed, but as last time I had this problem, there was a nasty metallic snap from under the car. So reversed it back into the shed. Checked the brake/ clutch fluid and that was about an inch and a half from the top. Does this sound like a typical slave mater cylinder failure? I've read that it can also be rebuilt with a repair kit. Is that worth doing or is it better to just change it out? Many thanks Clive Quote Link to post Share on other sites
Lebro Posted January 19 Report Share Posted January 19 Could be the flexible rubber pipe has shed rubber internally & blocked it's self, or a blockage in the master cylinder not allowing fluid to return to the resovoir, or a mechanical siezure in the slave cylinder. 1st step slacken the bleed nipple on the slave cylinder, & release any pressure in there, then see if you have drive (without pressing the pedal yet) do this in gear, wire to coil disconected, & with the started motor, so the engine won't start.

Smithfire67 Posted January 20 Author Report Share Posted January 20 Thanks Bob Yes, I bled the slave cylinder. That gave me some forward motion. I guess removal of said slave unit is the only way to find out if there is a blockage caused by debris fouling or the shaft is seized? Many thanks Clive Quote Link to post Share on other sites
EliTR6 Posted January 20 Report Share Posted January 20 Hi Clive I might be reading this wrong but surely the clutch is always engaged against the flywheel and should only disengage when you press in the clutch pedal? Could you engage a gear with the same engine running but there was no take up / forward motion when you let out the pedal? Best, Eli Quote Link to post Share on other sites
RobH Posted January 20 Report Share Posted January 20 From the description of the fault Eli, it reads that the clutch remains operated i.e. the slave cylinder is not returning properly to the 'rest' position so there is no drive. Clive bled the cylinder which let the pressure out and then the clutch did engaged with the flywheel, which means the fluid is not returning properly to the master cylinder. As Bob says - that may be due to a blockage in the flexy hose, etc. It is also possible that adjustment of the pedal drive rod to the master cylinder is wrong, so that the piston cannot retract fully.

Richardtr3a Posted January 20 Report Share Posted January 20 I had some similar problems with my clutch. In the end I replaced the flexible pipe and mounted the slave cylinder on the plate on the CORRECT side of the gearbox. I have had no more problems for at least 5 years. It may be worth a bit of research Good luck Richard & B Quote Link to post Share on other sites

We have had this issue before. Renewing the clutch slave flexible hose fixed the problem. Quote Link to post Share on other sites
Richardtr3a Posted January 21 Report Share Posted January 21 The improvement was having the slave cylinder mounted in the correct position which would be the " original slave position " and not the position that I chose firstly which was not correct. The length of the push rod is also important and must be adjusted correctly. My clutch works vey well and I remember struggling with it in the past.

I'll definitely be including changing that hose....many thanks Blue. Quote Link to post Share on other sites
