Hi guys

How difficult is it to change the clutch slave cylinder (1994 1.7 TD).
I'm guessing that is the culprit, as the clutch pedal has zero pressure unless pumped loads. there is also a drop in fluid in the reservoir. Can I do this job myself?

Just found this on Wiki, does it sound about right?

First you have to remove the battery, then remove the tray it sits on. This is only four bolts. Once removed, you can get clear access to the slave cylinder. It is held onto the top of the gearbox with two bolts (it is a good idea to loosen the hydraulic hose at the rear of the cylinder before you remove the bolts completely) then remove the bolts and throw the old cylinder away.

To put the new one on reverse the process but remember to bleed the fluid (you will need a friend to operate the clutch) bolt the replacement cylinder to the gearbox remembering to reattach the hose and make sure there is ample fluid in the brake reservoir.

You will notice a 7mm bleed nipple on the top of the cylinder. Remove it completely and keep an eye on the brake fluid as the level will start to go down (you will need to keep topping it up).

As soon as you see fluid coming from the bleed hole, screw the nipple back in but do not screw it in all the way!! This is when you will need your mate. Get him to push the pedal SLOWLY down to the floor AND HOLD IT THERE UNTIL YOU TIGHTEN THE NIPPLE AGAIN. Once the nipple is tightened, tell him to let the pedal up again. You may need to repeat this process a few times until all the air is removed completely. Once the air is removed and the pedal feels good, put the battery tray back in place, refit the battery and remember to check the brake fluid again.
