So every so often my clutch will let out a squeak when I'm letting it out in 1st, reverse and also when downshifting to 2nd from third 3rd. It's "meant" to be a brass button clutch?
Chrome Moly steel is slippery and slippery. Most button clutches I've drive are a little chirpy, especially if you're trying to slip them in first. Only asked about the fly because it's a common "package" type upgrade and it could be amplifying the noise.
Mmm. Yer I got no clue about the fly wheel. So nothing I can do to stop it? It just happens every so often
Sounds like your riding the clutch a little too much, not the best for these clutches. It is either 'in' or 'out' , meaning you will be a bit bouncy from stop when letting the clutch out When your down shifting try/practice 'heel toe' downshifting (rev matching) , it will get a little more life from your clutch and stop slipping + It sounds cooler
This one I'm not so sure about, I was doing it for a while but asked a couple of people that have HR and HA licences and they always say that heel-toe accelerates synchro wear. This may be fairly different between a truck and a sports car that you're racing but I haven't found anyone better to ask.
Heel-toe won't cause any synchro wear as your using the clutch at the same time, which shouldnt damage the synchros at all. Im not saying to rev match and shift without the clutch (thats what kills synchros)... check out a Youtube video of heel toe downshifting. I do it all the time in my car, you can actually slow down quicker under hard braking + less chance of activating the ABS which isn't the greatest thing when you are on a mountain run or somthing :br:
Yeah I know exactly what you're referring to, I did it for quite a while before I had to start wearing steel caps. I'm not sure how its supposed to cause wear but that seems to be the dogma among truck drivers, I don't think they would be considering clutchless shifting. My best guess is that reving the gearbox up in neutral allows the synchros to float between the gears and wears the teeth off. I would still use when on the track and driving hard, as you said you can land the gear quicker and aren't as likely to lock up the wheels under engine braking but driving around town I wouldn't consider it a way to reduce drive-train wear. Edit: Just did a little googling and found this from http://electronicdesign.com/archive/whats-all-double-clutching-stuff-anyhow So our gearboxes are different to truck ones, you're quite likely right on all counts. At least I learned something I've been wondering about for a while (how it increased wear never made sense to me)
