Mini clutch
« on: 05 February 2015, 20:29:27 »

Anyone know about Mini clutches?  The pedal doesn't fully return up when released.

Tried bleeding (but not reverse bleeding yet), no air came out, no difference.

Disconnect the slave from the release arm, there is a fair amount of play in the arm:






Don't know whats normal  :-[

looks like a 'proper' A-series to me?
I can't see the point of reverse bleeding it as it's a simple system and a short hose.


I'd be removing the cover and having a look at the bearing and the rest of the mechanism. At least Mini clutches are light work.

Only later A-series Metros were cable; early ones used the same hydraulics as Minis, 1100s and Allegros.

Where the operating rod goes through the aluminium cover is prone to corrosion and seizure,I'd be oiling that bit up then work the pedal to free it up

As per other comments... Could be corrosion related.

Agreed - and try reverse bleeding as well ;)

the rod into the clutch, as that's pretty free to be honest. That amount of "play" shown in picture I could do with my little finger.

That would be the shite bmw mini then  ;D
Sorry, I wouldn't have even graced it with my presence had it been one of those shitboxes.

This is a real Mini :y

It was restored to a good standard by the owner's dad a couple of years back, although the owner did learn to drive in it.  However, she learnt well, and wasn't too harsh on it.


I took it for a blat yesterday, the clutch works very well, its just the pedal only returns up a bit (enough to prevent any slipping, and I could lose front end traction from 1st to 2nd by being rough with it - so believe the clutch isn't shagged per se).

Up til a month or so ago, it used to return all the way up, level with brake pedal.

I don't mean the arm attached to the cylinder,I'm talking about the bit with the two nuts on :y

There should be a return spring, that hooks into a little metalclip on the clevis and back along the slave cylinder. I think there might also be one on the pedal, but can't be certain.

Yeah, that picture looks like it's missing parts 15, 17 & 18 from this list, to me: http://www.rimmerbros.co.uk/Item--i-GRID000968

(The larger picture makes it much clearer where they should go)

Come to think of it the picture looks like it's missing the clevis pin that links the clutch lever to the slave cylinder?
