Clutch Problem ?

[dikki10]

So I was driving slowly through my local car park and dropped it out of gear to slip over a speed bump. I then went to drop it back into 1st only for the clutch pedal to have basically no resistance and unable to put the car into gear ( any gear ). Anyway whilst awaiting the recovery I established that it will go into gear fine if the engines off. If I put it into gear and switch on with the clutch pedal down the car jumps forward. So basically like the clutch isn't there ... I've not had any issues running up to this such as slipping or anything - just seems to have come out the blue. Thinking about it I guess the biting point was pretty high but didn't think much of it as it's always been like that ? Anyone diagnose - I've not come up against this one ..

Cheers

What mk and year buddy.

Mates mk2 was a bitch to engage gears, that was solved by replacing a leaking slave cylinder and a complete fluid change!!

Common problem & usually sorted by replacing the slave cylinder. Could be the master cylinder but a slave is cheap as chips so start there first. I`ve had 3 go so always carry a spare nowadays.

You can get a replacement from Autolink

All as above...if you can throw a spanner or two , then easy enough to change yourself...give yourself a hr for your first ever go at one.

If it was perfect one moment then gone the next, it could be that one of the mounting bolts has fallen out of the clutch slave cylinder, I've seen that one before. Easy to check.

Hi Guys so I replaced the slave cylinder and bled the clutch extensively and alas its still the same - slack pedal , won't go into gear when running. When I bled it I was able to pump the clutch and pump the fluid through and when the nipple was tightened you could see the piston in the cylinder move ( a bit ). Does this mean it's going to be the master at fault and if so how on earth do you get it off as there seems to be 2 bolts one going through into the cockpit of the car and the other coming out through the firewall with a bolt on the end. Having watched some vids on youtube which was all done on left hand drive ones where it looks far more simple - How does one get at that bolt coming through the firewall ? working on the basis that I don't have an oompa loompa available with tiny hands :)

Without sounding bolchy (cocky) are you entirely happy that you have got all the air out of the system.

I used a pressure bleed system as I find it the easiest and best way to bleed brakes etc on my jack jones.

Masters do fail but not that often to my knowledge.
