Thread: v8 disco clutch bleeding help

Btw if you think that there's something else that could be wrong with it I'm more than happy for your opinion.

I had a similar experience in one of my cars, check where your lines come out of your master cylinder and run along the fire wall then down to the slave at the gear box. if the line goes above the hieght of the master before going down to slave you may be getting an air lock in the line which as i found impossible to bleed out, I parked on a very steep side slope or if you have flexible lines unbolt them and hold them down and mananged to bleed the system with no problem there after.

just an idea that gave me a headache chasing it!!!!!

My Disco did this too me ages ago, i ended up closing the Clutch reservoir cap and using a syphoning pump in reverse too draw through the clutch system under negative pressure too just before the slave cylinder it sounds stupid but you will eventually get it, Your wasting your time pumping the clutch pedal it will never work that way.

You will need to pump in the fluid from the slave cylinder up to the master. This method is very common on cab over trucks where air locks occur because of the way the fluid line is routed.
Get a small bottle that can be pressurized such as a Wurth pump bottle. If you can get a VERY large syringe from a vet that should also work.
To speed up the process, first remove the fluid line at the Master Cylinder and pump in the fluid from the bottom slave. When you see fluid reconnect the line and keep pumping.
Also check that lever ratio of the pedals are the same. If you cant push the rod far enough into the master you wont be able to throw the slave far enough to break drive in the clutch.

Hope this helps.
