Clutch/Brake pedal shaft

Post by zippy500 »

Hi,

Clutch stays on the floor if pressed with the brake pedal is presssed.

Could anyone let me know what parts I need to replace.

Is this an easy job to do.

Is this done from inside or outside the car.

Sorry for all the ques.

Thanks

Might just be a siezed pedal shaft. the brake and clutch share the same shaft. But the shaft should be held still and the pedals should turn on the shaft. I guess the shaft could be loose and turning. Ist thing to try in my oinion would be take the plate off where the master cylinder is and have a look see. Then I might try some penetrating oil on the shaft. If you lay on the ground you might be able to see if the shaft is turning.

Alternativley the clutch linkage is a common failure, but easy to service. If the linkage fails the pedal goes down to the floor and stays there.

is the clutch fully working on the car? can the car be driven? will help to define the problem.

The car/clutch drives fine, Just as your about to stop, when I dip the clutch pedal as I brake, the clutch stays on the floor, I just release the brake pedal, then the clutch pedal pops up!!.

Sort of semi-automatic transmission effect then ! Release oil and much wiggling of the pedals is the way to go. Could also be broken/weak return spring.

Renew clutch pedal(comes with shaft welded to it) and re-bush brake pedal, also worth re-bushing the bushes in the box section. You will then have a super smooth pedal assembly. Soak the bushes in oil for a day, before using, then assemble with grease.

This might help picture it. Image
The shaft and bushes were ok on mine but a bit sticky. I lubed the shaft with a spray grease, in a can, that penetrates like WD40 but dries out to grease. Worked great and a really different feel to the clutch.
Sorry about the surface rust in the chassis leg. It had been replaced 5 months back and was "rustproofed" by the person fitting it. Trust can be ok, but always verify. It looks better now.

We've got a similair problem that I intend to sort out this week.

Can anyone tell me if I failed to sort this would it affect the MOT brake test? (Cars booked in for 12th april)

Also has anyone fitted a grease nipple to the spacer and has it worked?

Thanks for the pic.

Mine had its MOT last month(passed:D ), Tester didnt mention it.

I was looking at ESM and the haynes manual( even more confused now) . Does the brake pedal fit on the clutch pedal shaft, or the clutch relay shaft. :-?

Zippy it goes on the clutch pedal shaft, Paulk, I have put a grease nipple on the brake pedal bush area, but not the spacer
. It had been replaced 5 months back and was "rustproofed" by the person fitting it. Trust can be ok,

If the brake pedal isn't sticking, I can't see why it would. Not sure I'd be happy about driving it knowing that the pedal was potentially dodgy, mind :(

This will normally pass an MOT - the brake test is done in neutral on the rollers, therefore the tester is unlikely to realise,
You find this when driving but is most likely to be a problem when braking and engine braking - as you change down the clutch stays open. On a Minor this is a serious fault! I've had a few cars with this problem and although it's possible to ignore (momentary release of the brakes to allow the clutch to engage) it's best to fix it ASAP.
On mine, they all had a severely worn pedal shaft. One had ok bushes in the brake pedal (maybe they had been changed by previous owner) but the others needed bushes as well as the shaft to be fixed.
Easiest way is to exchange the clutch pedal and shaft for a recon one - or get the new shaft and have to re-weld the clutch pedal onto it... or if you have the right equipment, you can weld up the worn areas of the shaft and grid it back to size.

On one car, the spacer had rusted fimrly onto the shaft - this means you can't dissassemble anything! That one took me a few extra hours to sort out (I ended up welding onto the spacer in order to turn it on the shaft).

well I have started to dig into the footwell and have a look!!

After trying to remove half a dozen screws, all the philps heads where rounded off. Then came the good bit.

Are the panels "putted down" from factory. had to scrap the gunge off the screws.

Do theses panels need resealing when replacing?

Managed to lift a small piece over the master cyclinder. Brake pedal does have a lot of play in it. Will continue tommorow(time(wife) permiting)

I am impressed that these parts are accessable from inside the car :)

Amazed you can get your wife to do this for you - well done. Allocate her a bit more time tomorrow !! Yes - the panels are seated into dum-dum like material - and yes it's a good idea to seal them again to keep water out.
