Right, after the GREAT cruise out last night with a few of the ashord minis. As I got home, My clutch got a bit sticky.

Basically, When I put the clutch to the floor, It comes up REEEEALY slowley. So ive found myself only putting the clutch in just enough to allow it to change gear. THat cant be good for it.

So I need it soring FAST.

Any ideas?


Its a Competition clutch, and Ive got a KAD quick shifter too...



Clutch takes a long time to return when I take my foot off it. VERY annoying.

What do you mean by competition clutch?


Change the return spring above the slave cylinder.

which type of clutch do you have fitted

verto or pre verto ?


also try prising the lever arm from inside the engine bay, how hard is it to move the clutch lever arm

not sure on the clutch. But I do know that it has always been a very firm / stiff clutch pedal.

A friends dad had a drive and told me thats because it is a "Competition Clutch". He said that the springs on the clutch are firmer springs to cause a faster return? :D

Its a different language to me. :tongue:


Can I ask, Is the clutch hydraulic or cable?

Could it be that it needs "Bleeding"?



Return spring? Jammy, I shall pop by and let you do it for me! :cheese:

Ill pick up my 1430 engine while Im there... :P

definatlly hydrolic, and this wouldn't normaly cause the pedal to be slow on return, as jammy said have a look to see if the spring hasn't come off..

as for the clutch when you look in th engine bay, do you have a liitle or a big clutch lever arm

where abouts am I looking? :D





I drove the car this morning, And the clutch was TERRIBLE.
I parked up at tesco, ran in and got a sandwich. When I got back to my car to drive the rest of the way to work. It was fine. All the way to work until I was pulling up into the carpark. Then it went all nasty on me again. :erm:

left hand side of the engine! there should be a slave cylinder and an arm that comes out of the centre off the cone shaped clutch housing

just had the same problem with mine mate, it was the master cylinder, the pedal used to engage and disengage the clutch but the pedal wouldnt return. master cylinder rubbers was causing the liquid to stay on the wrong side of the rubber restricting the pedal from returning. simply (or not so simple) either change the rubbers on the master cylinder, or replace the whole thing, while ur at it u may aswell give the slave a service. im 90% sure its ur master cylinder

:gasp: Master cylinder???

poo, Is that hard to do then?



Well, I went home and sprayed white grease allover the pedal box and it seems ok now.
Still not 100%, But its drivable. :tongue:


So who wants to check my master cylinder?

Binge, you still have not determined what sort of clutch you have... Verto or Non-verto...

All the above about springs could well be irrelavent...

1. does it have a long arm with the slave on the top of the transfer case.

or...

2. Does is have a short arm with the slave attached to a plate on the side of the bell housing...

There are also springs on the pedal which help it return to it's normal up position, chek this has no failed...

but other than that the most likely cause is a restriction in the pipe ( hence the heavy pedal ) and also the slow return, as the fluid has to be forced back into the master by the clutch spring.

Ok, to find out what type of clutch you have. The slave cylinder is the bit that sits on top of the flywheel cover, has a pipe going into the end that nearest the radiator, and a 'arm' that goes to the middle of the clutch cover. If the slave cylinder is horizontal you have a pre-Verto clutch, if it sits at an angle down parrellel to the arm that goes into the clutch cover then you have a Verto clutch.

This can also be a problem with the rubber hose feeding the slave cylinder...they can start to break up inside and so sometimes restrict the flow and sometimes not.

Easiest and cheapest thing to try first !!! :grin:
