dani_r Posted March 9, 2009 Share Posted March 9, 2009 I've just been speaking to CW about my Supra's clutch problem. When I go to change gear I push the pedal in and it feels light, then when I release after changing gear there is only a small bit of bite right at the floor then the rest of the way up there is loads of play in the pedal. Sometimes it's ok, but most of the time there is lots of play in the pedal, only biting when it's right near the floor. Chris said it could be my pressure plate collapsing (or something?). Has anyone ever had this or know any more? Thanks Dan Quote Link to comment Share on other sites More sharing options...
mike_mcevoy Posted March 9, 2009 Share Posted March 9, 2009 my advise would be drop it down to South Coast and get then to visually examine it either via the inspection panels (Although I'm not sure if the 5 speed have them) or to just whip the whole gearbox off. Its easy enough to get a new release bearing or pressure plate from one of the traders here depending on what is failing Quote Link to comment Share on other sites More sharing options...

dani_r Posted March 9, 2009 Author Share Posted March 9, 2009 Ok, so I went out to check fluids etc and to try the clutch again, the fluid was all black and crappy, and when I tried to move the car the pedal stuck completely to the floor and had to be physically pulled up again! I've done some searching and this looks like master/slave cylinder? Could the crappy fluid be responsible? Looks like I need some bits! Anyone have these available??

jevansio Posted March 9, 2009 Share Posted March 9, 2009 Mine did that, turned out the bolts holding the release fork on sheared clean off Quote Link to comment Share on other sites More sharing options...
dani_r Posted March 9, 2009 Author Share Posted March 9, 2009 I'm still getting a little bit of clutch, but it's right at the very bottom, and it's only once or twice then it goes completely, then I have to pull the pedal back up and then wait a moment, some pressure comes back then I can use the clutch and the cycle continues. Unlucky about your release bolts, gear box out job then? Quote Link to comment Share on other sites More sharing options...
jevansio Posted March 9, 2009 Share Posted March 9, 2009 I don't think so, it was clutch replacement type job Quote Link to comment Share on other sites More sharing options...
edge Posted March 9, 2009 Share Posted March 9, 2009 Change the fluid in it 1st. Cheapest option 1st if you can do it yourself but sounds like it needs to be done anyway Quote Link to comment Share on other sites More sharing options...
dani_r Posted March 9, 2009 Author Share Posted March 9, 2009 Does anyone know what kind of price these units go for? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 9, 2009 Share Posted March 9, 2009 As I said on the phone, flush it out with fresh fluid, if the pedal's sticking down it could be the fluid's so manky that it's blocking the return hole on the M/C. You could get 2 seal kits and re seal both cylinders. Now you have described the condition of the fluid I am fairly sure it'll be a hydraulic problem Quote Link to comment Share on other sites More sharing options...

Now you have described the condition of the fluid I am fairly sure it'll be a hydraulic problem Thanks again Chris I'll have a look at that tomorrow, just need to nurse the Supra to the workshop! Just another quick few questions: Is it just standard Dot 3 or 4 brake/clutch fluid? How much do you think i'll need for a complete flush? Can I buy the seal kits from Toyota or someone on here?

mike_mcevoy Posted March 9, 2009 Share Posted March 9, 2009 A fellow IoM Supra owner? Finally! Where is South Coast? they're down next to the power station, about half way down to the civic amenity site. Mine did that, turned out the bolts holding the release fork on sheared clean off exact same thing that happened to mine, but also could be a seal gone in either the master or slave cylinder (had those changed before opening the inspection plate and nearly having the fork drop on my head) Quote Link to comment Share on other sites More sharing options...
dani_r Posted March 10, 2009 Author Share Posted March 10, 2009 OK, tried a fluid flush today and it did not go well Put new fluid in the top after using a syringe to get most of the old fluid out, opened the bleed nipple and did the push-stop-pull thing as mentioned many times. Not much fluid came through the bleed nipple and the clutch is still having the same problem where it pushes pretty much to the floor if you hold it there and doesn't come back up, it has to be physically pulled back up. There are no visible leaks from either cylinder, also there doesn't appear to be a loss of fluid. I'm thinking maybe the seals in the master cylinder have gone? Any thoughts?
