Hello, I mentioned this a few days ago, When slowing down in any gear i can feel the clutch pedal moving in and out slightly under my foot. This is with the clutch out, not as i'm lifting up. It feels like its tapping the bottom of my foot when my foot is just resting on the pedal.

I was told to check the bracket that the top engine tie bar bolts to. This seems to be fine. The engine tie bar bushes are fine too.(poly bushes). I'm not sure about the actual engine mountings although the engine seem very stable when i try to rock it. Could it be the bushes between the subframe and the car? How many are there and where can they be found. (I think i know of 4) Thanks

I'm afraid you have probably been misinformed about what to look for. The Mini clutch is hydraulically actuated. Engine motion won't be transmitted to the clutch pedal. It wouldn't be likely to happen with cable-type clutches on other cars either.

I you have a Haynes manual, read up on how to adjust the clutch. You probably have a verto clutch so I can't comment on how to adjust them. However, it will be similar to the early clutch mechanisms. These must be adjusted to set the position of the throw out bearing and to control the stroke of the throw out bearing when the pedal is pushed.

I suspect what has happened is your clutch may not be adjusted correctly and the throw out bearing is riding on the springs of the clutch plate. Any wobble in the clutch will create "small" pulses in the fluid... but I'm still surprised that you could feel it through the pedal. Start with simple clutch adjustments and see if the problem doesn't go away.

by the way, it's not a good idea to ride around with your foot on the clutch pedal anyway. When you drive around with your foot resting on the clutch pedal you are creating unnecessary wear on the throw out bearing and the pressure plate which aren't normally in contact with each other while driving.

With the engine steadies, what I was illuding towards was not actually a vibration through the clutch system, but rather through the bodywork into the pdeal box as a whole...

But as you have now ruled that out, you should now, as DK has said, concentrate on the actual clutch mechanism.. but I'm still of the feeling that movement through the pedal is more likely to be mechanical rather than hydraulic, as the master cylinder will act as a damper to hydralic fluctuation.

If it only happens (or is worse) when resting your foot on the pedal (gently) then you may well have a failed clutch release bearing.

But either way GW is right about it being mechanical, as something is "pushing" back at the pedal.

Do you get any untoward noises ??

And has it been doing this for a long time, my guess is that it started with a noise which then subsided and the "pushback" is now evident ???

Does it change gear ok ? with no "clunking" in to gears ??

Its always done it since I got the car 18 months ago. The clutch is stiff and it's sometimes tricky to put it into 1st when wanting to pull away. Apart from that its seems to be fine.

There is no noise with it. When driving I think the engine is moving back and forth more than it should, but It seems so solid when I try to rock the engine myself.

I didnt want to create a new thread so I used this one sorry lol

Ive got a 1990 Mini,

The clutch pedal is getting very close to the floor now and tad to close and has about an inch of play before it starts to even move the clutch plate.

I know how to adjust the old type, but this type,, I just cant see anywhere to adjust it, its just a cylinder and arm, thats it? lol. Theres no way to push the cylinder forwards so how the heck do you adjust it?

Its not slipping and is changing fine, but Id like to know anyway

I just came accross this post,
my clutch does exactly the same thing it feels as if the clucth plate bounces if i put my foot down on it too hard when coming upto a junction, i think i have adjusted it properly because there are only two places you can adjust it.

i reckon its my release bearing

Bloody verto clutches are a pain in the ass im gunna get the non-verto with my new engine soon

I know this is an old one but I too have the same issue on a car I have just purchased.

Anybody fix it or is it just a quirk?

I'd be looking at the flexy hose to the slave cylinder for twists and also the crankshaft end float.
