Air bubbles in clutch master cylinder
I have converted my mini to manual from automatic, I have used parts from my other mini that is work in progress they have not been used for 2 years. would this be cured by new seals or would I have to replace the unit?. The slave cylinder bleeds up ok but you can hear and see the air bubbles in the master cylinder as you press the pedal. Any help gratefully received.

Fantastic. Is there any visible difference between the two as the cylinder came from a 74 car but i am unsure of the year of the cylinder

Clutch Master Cylinder Explosion
Hi there After successfully replacing the slave cylinder, I sat back and was in awe at my own fine handy work. And thats when God noticed me and the fact that something on my car now worked. Unknowing of the godly powers that hung over me I then thought it would be a jolly good idea to bleed said clutch. Out comes the eazi bleed kit as per usual (I dont have many friends ) After attaching the kit and then using a tyre for the pressure, the bottom of the already antique master cylinder decided to finally give up and remove itself from the car. Anyway story ends here. How much would it be to remove and replace the MC if is was to ask a mechanic? Any rough guesses Cheers Paully

Replacing The clutch master cylinder is straignt forward job, just undo two nuts at the base, remove the pin from the pedal (can be tricky getting there), undo the fluid line and fit the new master. Not really worth taking it to a mechanic. It actually took me less to change the master than the slave cylinder and if youre capable of the latter....

Plastic master clutch cylinder
Want to warn all LHD Mini owners to reflect on the selection of which of the cluch master cylinder to buy.
Be a "purist" and choose the more expensive metal version in front of the plastic one.
It looks like I have made it myself when mounted in the engine compartment.
Probably it will suit the RHD car better an not show the metalclamp holding the plastic tank, towards the front.
You do not get this info from the picture in the add!

Re:
Have you checked the clutch master cylinder fluid level?

Rock Hard clutch pedal
Thanks Tim
I have replaced the Master Cylinder already and i stripped the slave to see if it was seized and it was fine. When i open the bleed valve on the slave it goes down no bother. If i leave it for a day or 2 the pedal will go down only once then brick hard again. The clevis pin is in correctly because it was the bain of my life doing that Master Cylinder.

Clutch pedal seized
your mini is 1990's so the brake master cylinder will be located on the brake servo. that leaves only one master cylinder on the bulk head which is the one or the clutch. To bleed the clutch cylinder it will be easier and cleaner (BRAKE FLUID STRIPS PAINT) to use a pipe kit from halfords. Go easy with the hammer on the clutch arm as you can easily crack the clutch housing if it's not already cracked. You may have to remove the split pin from the pivot pin and take it out before cleaning it all up with sand paper and reassembling with copper grease. Have fun an GOOD LUCK>

Clutch Pedal
Does anyone know how to get the pin into the top of the clutch pedal (into the master cylidner) without having to break your wrist in 3 places?

mini 850 won't go in gear
I would say its more likely a clutch drag problem. Firstly make sure that the fluid level in the clutch master cylinder reservoir is correct, should be level with the bottom of the filler orifice. Next try bleeding the hydraulic system and see if that makes any difference and also check and adjust the throw out on the clutch arm. If it still wont engage 1st with the engine running you may have faulty seals in either the clutch master or slave cylinder.

Clutch pedal locked
Yes, it's most likely the seals in the master cylinder. It's an easy job but removing and refitting the cylinder is tricky - especially where you have to disconnect the clutch pedal from the push rod at the back of the parcel shelf. You'll need long-nose pliers to get in there.

Clutch
During the Bleeding of my clutch i am getting constant air threw the system - I have removed the master cylinder in view of renewal but there seems to be no sign of fluid leak - Could the master cylinder still be at fault?? Is it also worth renewing the slave cylinder?? The is not visible sign of flid leak here.

HELP Clutch?
When you bled the system, did you actually get any air out? It can be quite tricky sometimes to get the clutch master to start pumping - sometimes the piston will stick at the top of the cylinder and no amount of pedal pressing will budge it.

Gear selection problem
crunchy gears is usually worn syncro but it sounds in this case to be a problem with fully disingaging the clutch, id gess one of the cylinders may be sticking or problem with fluid, like a leak or air in system. may need a new master or slave cylinder but change of fluid would be first thing to try.

whirring gearbox
i had the same issue, however when i checked my clutch master cylinder and the fluid was a little low, add some dot4 fluid and see if it helps, then might be worth check master + slave cylinder for any leaks

Can anybody help, i have a rock hard clutch pedal which just seemed to happen on its own as it was fine before. There is a new Master Cylinder and the slave seem OK
Posted: May 21, 2010 09:51 PM
I would disconnect the clutch arm, and see if you can now press the pedal (get an assistant to do this, whilst you hold onto the end of thepush rod to prevent it escaping and losing brake fluid everywhere). If it still doesn't move, then it's your master or slave cylinder. Or it may even be something obstructing the clutch pedal (did you put the clevis pin back in properly?). If it does move, then it's the clutch arm itself stuck. try and move it by hand - it may just be rusted in position (quite normal if it's been standing a while)

Clubman clutch
I've just replaced the clutch and the master cylinder but now I can't get it into any gear as it crunches, what is the most likely thing that I've done wrong ??? I've lined up all the "A"s on the pressure plate, flywheel and housing and bleed the cylinder, what's my next step please.
thanks Neil

Verto clutch
Hi now I’m having dramas with clutch ive being told by my grandad that putting a pre verto clutch arm and master cylinder on my verto clutch should be fine even though I said I’m pretty sure this isn’t a thing now just to clear an argument up because now when I’ve turned the car on and press the clutch even though there is movement in the clutch arm I can’t select any gears and I guessing this is the reason why any advice on this subject would be greatly welcomed as I’m just an amateur and teaching myself and learning as I go
