Vague Clutch Pedal

[StuDoc 72]

Right I have a strange problem i thought my clutch was becoming weak and the biting point was vague along with being quite high so i changed my clutch, altho when removing the old clutch i notice it has loads of meat left on it. Anyway its changed.

So the new one is in yet there is very little differance my next port of call is i have a new loghtweight toda flywheel to go on as i thought if its not the clutch that was worn maybe its the flywheel and that is causing a greater distance before engagement.

Anyway i sold on my other clutch and it is now fitted to another glanza and i have felt it in that glanza and it feels perfect a nice distinct obvious biting point half way up the travel. So this has had me thinking could there be more to it. Has anyone experienced this before??? So I've seen the master and slave cylinders are fairly cheap and both can be bought for under 100 pounds. So i want to know if anybody knows which one of the 2 is more likely or will it possibly be my flywheel after all as ive yet to fit it.

Anyway opinions would be appreciated as its just something daft thats annoying me.

Cheers

Slave cylinder ? Fresh fluid ? Rubber pipe ballooning ? Id try fresh fluid first bud

Fresh fluid done mate. forgot to mention that. The bottom of the master cylinder had some amount of gunk in it i was shocked obv had never been changed. I dont think its the flexi that seems ok. Im defo caught between the flywheel master and slave cylinder.

Can see me ending up changing the lot lol. Just though someone else might have experienced this on their starlet or another car being that its the clutch any car could have the same symptoms.

Only problem I ever had was on a colt and the slave cylinder packed up I couldn't get any gears and the pedal wouldn't move hope you get it sorted pal. May sound silly but did you bleed the system enough when you change the fluid ?

[StuDoc 72]

Aye i think its either the master cylinder or the flywheel tbh because if it was the slave cylinder then like u say would make getting gears hard and the biting point would be lower to the floor rather than higher. So ill just have to change the flywheel over and see what its like and go from there. Aye its bled right thru.

Must be one of those 2 things its hard to explain its just that way normally u can distinctily feel the biting point on a car well you just cant on mine untill your moving lol.

Have you checked to ensure the clutch pedal is at the right height as this can affect the way you feel it...

When changing the clutch I would expect the clutch pedal to be adjusted to suit a new biting point.

Also did you replace the release bearing?

I suspect its not that mate as the pedal seems to be the right height its level with the others im sure im a mechanic so ive went through most of the general things. Ill have a go at checking this tonight though and see if it helps. It really is wierd its really like u cant feel a solid biting point. Thats wots making me think now that it might be the master cylinder.

Aye mate replaced the bearing the old clutch felt like it was slipping a bit thats what led me down the road of the flywheel my theory was the flywheel was worn down causing the friction surface to be further away from the friction plate thus causing my high biting point and lack of definity but the more i think about it the less sure i am maybe just me over thinking things lol.

Hmm it could be either the master or slave cylinder, although I have known it to be more commonly the slave cylinder to give a "lack of pedal feel"

I'm sure you can pick these up for around £30 second hand.

Bit of a ballache if it is the flywheel as you have only just had the gearbox off. How was the flywheel when you replaced the clutch?

[StuDoc 72]

I think you can get the slave cylinder on egay for about 20 or 30 quid brand new or maybe idrees does them ill find out and give that a bash. wwll ive just bought a toda flywheel so i wanna stick it on anyway. I didnt even feel the lip just checked it wasnt cracked or ridged. Ill try the slave and fly to start.
