clutch buzz and master cylinder problems

[9000RPM]

Hi there, reviving this thread one more time :P

I'm starting to get sick of the clutch buzz in my car, and I was wondering if it is suitable to only change the clutch disc instead of the whole clutch assembly?

My car is still on its first clutch and is currently on 85,000km but its working 100% fine, no slipping or any issues whatsoever besides the loud buzzing on deceleration. So I don't want to change out a whole clutch if I don't have to, only want to change what I need to in order to get rid of the noise!

I guess the other thing to consider is if it would be alright to have a new clutch disc installed while the other parts of the clutch assembly are 85,000km old?

Some advice would be much appreciated

Technically you could only change the friction plate......... but why??? While it's out, replace the lot. Everything about the factory item is crap. So replacing it with a better item makes perfect sense and the price difference between partial and full replacement wouldn't be that much different.

Everything about the factory item is crap.

That's a pretty harsh and sweeping comment. Care to back it up?

[JAP-S2K]

So what makes it so good then? Care to share and expand everyones brain. What's harsh about my comment. In factory form, the clutch is weak and slips between gearchanges with spirited driving and is noisy (clutch buzz).

I didn't say it was good. You said it was crap and didn't justify your comment. i call that 'harsh'. YMMV

Contrary to your opinion, many have been on the stock clutch for up to and over 10 years without problem (including 9000rpm). It is strong enough for general and even spirited usage.

Yes, the early ones had a buzz issue but this was entirely cosmetic and certainly not justification for calling it crap. And any OEM replacement that you buy today won't buzz.

Ok, I agree if you want to beat on your car, or have extensive mods that add double digit power increase you might wanna upgrade your clutch. But you might wanna consider replacing your diff too for that matter.

Now, here's a bit on my experience:
Yes, I have an uprated clutch. It's an Exedy HyperSingle. Before that I had a custom rebuilt OEM unit from Race Brakes.
And yes I have some mods. If a turbo counts as a mod. Before that I was supercharged.

But....
I didn't feel the need to upgrade my clutch until I went SC. And I did a fair few track days on the OEM. And whatever you do, don't go Exedy HyperSingle for bragging rights. Yes it holds the power but it's a pig in day to day driving.

All I'm saying is I disagree with your statement 'Everything about the factory item is crap' and propose instead that a more correct statement is 'the OEM clutch has it's limitations'.

In summary here's my answer to 9000rpm:
Yes, if your only problem is the buzz you can replace just the disc and you will get rid of the buzz and extend the life of your clutch.

But it's a lot of work and on an old clutch. May as well replace the lot. OEM is apparently suitable for your needs (as you don't seem to have an issue other than the buzz) but the Exedy (HD??) is the same as OEM (Honda license the Exedy) and can be got cheaper.

Thanks for your helpful reply. I was looking around on the net and this seems to be the one:

"Exedy OEM Clutch Kit for Honda S2000" Part #KHC06

And would I be right to assume that all Exedy clutch kits that you buy now will have the new clutch plates which are free of clutch buzz?

[AusS2000]

Yup, no buzz.

[drsilliez]

what does the clutch buzz sound like?

[garett]

its like a whine when you back off the throttle at higher revs

while mine is there its not bad. as the car is very raw standard it doesn't seem out of place IMO

[s2kjn]

Yes..... but it may come back if you use the Honda OEM replacement.

Just upgrade to an Exedy HD.

I upgraded to exedy HD & still have the buzz...

^ As we later learnt, the Exedy HD IS the Honda OEM clutch.
