Clutch master cylinder
Posted: 07 Feb 2010, 12:52
Looks like I have a fluid leak from here, anyone have any tips for replacing the master cylinder.
I got this off the wiki some time ago but can't find it now, anyway this should help courtesy of VWCamperfan

Thats your clutch master cylinder. Bit of a pain in the backside to change as its up above the clutch pedal but so long as you have contortionist abilities you shouldn't have a problem!
Here's how it goes...
Undo black top-up cap on fluid resorvior, place some cling film over the top and do the cap back up. There is a reason for this... Tell ya later!
Undo the two securing bolts that hold the master cylinder in place.
Undo the pipe that leads to the slave cylinder.
Remove the flexible pipe from the master cylinder that runs from the resorvior and block the end with something ie. pencil. (Ps. the cling film should prevent most of the fluid escaping by creating a vaccuum!).
Remove master cylinder.
Put in new cylinder ensuring small pushrod from pedal is located in top of cylinder casing. Replace the two bolts securing cylinder in place.
Pull your pencil out and reconnect the flexible fluid supply pipe to the master cylinder.
Now... If all goes well you can pump the pedal a little until fluid squirts from the threaded hole to the slave cylinder. When this happens, reconnect the pipeline to the slave cylinder and with any luck you won't even have to bleed the system as you have removed the air already.
This was how I replaced mine and I didn't have to bleed the clutch circuit after reassembly.
Have fun!
