Clutch Master Cylinder Advice?

[Fireyred]

Hi,

Over the last few weeks it has become hard to change gear on my 90, and is now at the point of no return as cant get it in gear at all now.

I have now been informed by a reliable sorce that it is the Clutch Master Cylinder?  which is good as there only around a £10.

After looking at mine I took the lid off and noticed that the pot was empty, could someone please advise me as to what fluid/lub needs to be in the pot as will need to get some for the new part???

Cheers

Clutch/Brake fluid Dot 4. :)

Thanks, would you advise getting a new one and filling it or fill the old one and see how it goes?

Might as well try the old one first, but youve got to ask wheres the fluid gone??? Is the slave cylinder wet? Leaks around the pipework??

Funny you should say that as just read an article about changing the Clutch Master Cylinder and it says change the Clutch Slave Cylinder also as they tend to both go at the same time. Gonna pop outside and have another look at it now.

Did notice what seemed like water in the Master Cylinder pot when I checked it, felt dampness inside, like greasy water.

How easy is it to change both? Dont mind getting my hands dirty  

Cheers

Slave.... 30 mins max, undo pipe, unbolt the 2 bolts holding it on, slip new one in place, bolt up, re-attach pipe, bleed, cost you around £8.  Mine went last week, bleeding is a b***h, 2 man job.

Check the bottom of the flywheel housing where the plug hole is, (if there is no plug in there)and around the slave base and theres fluid coming out the chances are its the slave.

Master......dunno, never done one!!!

Well they are not to bad to do at all, take the plate at the top of the master cylinder off, the one secured with the six screws. go inside the cab & remove the lower panel that covers the pedal area, remove the six 8mm bolts 13mm head. Go back to the engine bay & remove the pipe then you can take the whole clutch box out. Change the master cylinder then re-fitting is the reverse.


as for the slave i would advise to change or check the flexi pipe as they can rub on the chassis!!! Remove the metal pipe & then undo the 2 8mm bolts (13mm head) & remove the slave, refitting is the reverse.


BLEEDING THE SYSTEM
you can do this on your own, its quite easy. make sure all the pipe unions are tight, undo the bleed nipple one full turn & top up with fluid. Jump inside & give the pedal a couple of pumps, keep topping the fluid up & let gravity take its course. then after a couple of minutes lock the nipple off, top up if required & give it a go. If it feels ok try it & make sure you have got the rod length on the master the same as the old one!!


Hope that is of some help??

Thanks for that.

No problem mate, i did mine the other week & it works fine now, like driving a new landy  :lol:

When changing the slave, be carefull that the rod doesn't come off the release fork cos its a bugg3r to get back on.

[kevinf]

i would suggest you fit a genuine parts master cylinder,because the last time i fitted a cheap copy the push rod lenght was slightly too long even when fully adjusted and even though i had a very good pedal the clutch
would slip occasionally under heavy load,ie hard driving/towing and off-roading

If the master cylinder is the problem it more often than not leaks fluid down the clutch pedal and onto the floor. The slave cylinder leaks into the clutch bellhousing and then drips out of the wading plug hole. As Tonycougar says - careful you don't pull the operating rod out of the fork. Use Genuine parts - some after market stuff is really poor quality and the difference in price isn't that much. Thread on replacing the clutch master on a Defender:-

Clutch slave change on a series/defender (the job is pretty much the same)

Hi,

I normally get my parts from Paddocks and not had any problems with any so far. Not ordered then yet.

As friend said try to just fill my Clutch Master Cylinder pot back up as it dont look that old, then see if we can see where it's leaking from and go from there. As it could be something simple like a lose nut.

Chances are I will change both parts anyway's. As i'm just unlucky :(

Although after looking at the above posts and the links am a tad concerned I wont be able to do it myself really. Even with Big Rich's help. But will give it a go.:?

Thanks all for input everyone, being part of Mud Club is a big bonus.

Thanks to all for advice, have filled the little pot with Dot 4 fluid, and its been fine the last 4 days.

Fingers crossed it was just that.

cheers once again all for your help.
