Hi All,

Not a good start to a sunny Friday. I have gotten into my beautiful hippo this morning to a solid clutch pedal. Pressed it once more and bang the pedal is on the floor. Yesterday it was fine with no problems so strange its happened today. Does anyone know what it could be?

I have a couple of ideas.

1) Master Cylinder bracket has popped off
2) Clutch cable has broken
3) Master cylinder rod has broken
4) The Master Cylinder coupling has popped out.

I have not had time to check as I was going to work so had to leave it.

Edit Sorry this is a hydraulic master cylinder.

Knowing what engine and the year of the vehicle will help.

Edit. Looks like you have a TD4 FL1.

You will probably find that the slave cylinder (known as a concentric) has failed.

Look under the gearbox bell housing, to see if any fluid is leaking.

when I learned to drive, in the military many years ago, they taught you how to drive without a clutch, first start the engine get it warm, once warm turn it off engage first gear, and hand brake off start the car, then change gear by using the revs dont rev up to go up the box, but you do coming down, its away to get home if when your out you have clutch problems I have used it a few times just takes a bit of practice

I have had a close look now and its the slave cylinder what a joke, its brand new and new clutch. The coupling has blown apart will this mean I still need to change the cylinder or can I just reconnect it?

That would depends on if the threads are damaged in the slave, connecting hose or both , as you said luck its at home, safe bet it to replace both, you have already lost the fluid, so its a no brainer

OK I see what your saying but if its not repaired 100%, how long will you be standing on the side of a road waiting for recovery and then how much in a garage to fix it,

Take the time an fix it now and save your time and money later!!

Just reconnected the slave and its connected with no problems. but the Master cylinder is leaking inside. Does this mean the master cylinder caused the slave to blow out?

I would say not, it will hold the pressure out put of the Master, if the hose connection blow of the slave then that may mean that it was not tightened correctly, or a miss match in the thread size, if the Master is leaking internally then it either need replacing of rebuilding with new seals,

Hi all,

It was the master. Brought a new one today and fitted it. When clipped the pedal on it was solid. So connected it to the slave and surprised got a clutch.

Love pre bleed cylinders.

my wife and daughter for my 70th the paid for me to drive a mac truck and you could drive it without the clutch but with a truck that size you did have to use the clutch for 1st gear but I used to do it years ago so it was no problem
