Default Clutch Bite Very High (New Clutch)

Right on my new car the clutch is extremely high. To the point where you think you are almost completely off the clutch and it bites. There is no slip at all and I have a receipt that says the clutch has been changed recently.

I have read a couple of things about adjusting the pedal. Is this something I need to look into or should I be looking a little deeper?

Cheers

I'm assuming the clutch slave was bled? Who fitted your clutch?

Clutch slave definately doesn't require bleeding unless hydraulic system was opened.Which isn't required.

How do you or the OP know that it wasnt opened or did the OP do the clutch himself?

I don't know if the system has been opened. Hence putting "Unless". I would have thought that if the bloke has a receipt saying that the clutch has been replaced,that he didn't do it.

why would it be opened on a clutch change though? The slave is externally mounted so just gets unbolted to change a clutch leaving it closed.

It could have been opened at some point yes, but will have been for another reason if so.

Adjustment under pedal?

Kris is correct in that there is some adjustment on the rod leading into the master cyl. It may be worth checking for adequate free play.
If the clutch needed bleeding, the pedal would go down too far, rather than be hovering at the top when you lift your foot off.
We often encounter this one with uprated clutches, my feeling is not all of them are set up that well from the manufacturers. They don't often actually slip, but it can take a bit of getting used to when it comes to the feel of the clutch at speed, particularly on the downshift.

Thank you all for the responses so far.

A little further information that may help...

The clutch was done under the previous owner by a comapny called AFR in Crawley in April. I have a receipt which says the clutch was replace with an Exedy Organic Clutch and the Clutch Slave cylinder was also changed at the same time.

I also have a receipt from the same company 3 months previous that says the clutch pedal was adjusted and the clutch system bled.

I don't want to just adjust the clutch pedal if it's masking a different problem. But at the moment it definitely doesn't feel like a a 7 month old Exedy Organinc clutch to me.

Many thanks,

Giles

Hey Giles.
If the disc only has been changed and not the cover or the release bearing,then you could have some worn down fingers on the pressure plate as well as wear on the bearing face.Also the organic disc could be thinner than the original one that was fitted,causing a height difference with the pedal.Hopefully the slave is the right one.If the pushrod is too long,it will give a high pedal as well.Just some food for thought.Obviously sounds like an adjustment issue as its not slipping and assuming the engagement is fine.

Oh yeah.And previously the clutch pedal was adjusted to mask the worn clutch and the system bleed.After 3 months this didn't cure it.So,the clutch and slave were replaced and the pedal probably not re-adjusted.

Nice one, I've got a spare slave cylinder fortunately so I may adjust the bit under the pedal and if that fails swap the slave cylinder for my other one.

Worse case scenario is gearbox off and parts replaced.

I always thought when you ordered a clutch it came in a kit with the cover and bearing, is this not always the case.

Once again thanks for the help (I don't know what I'd do without Scoobynet!)

All of the clutch kits I use whether they are SACHS,Valeo,LUK etc.etc. are complete kits with cover, disc,bearing and bolts.If necessary matching flywheel as well.Some people that do things on the cheap may just renew the disc.There are specs for measuring finger length etc.But,if you have the box out and don't fancy doing it again and again,put a kit in it.

Just wanted to report back on this as I changed my very old and black looking clutch fluid today.

As described in other threads took the TMIC out of the way first to get a clearer access to the bleed nipple.

Anyway now fresh 5.1 in there and fully bled the system.

My own qiute high biting point is noticeably better, I'd say just above half way instead of at about 3/4's.

So if I were the OP, I'd definintely bleed the system as has been suggested on here!

Hope it helps, Chris
