Cant get at it to tell with what Ive got with me, can see it, and reach it, but cant get the lid off.
Cant see it looking low, and brakes are fine, so would expect to be able to identify if it was only half full.

There's a 'wall' inside the reservoir so that if you completely lose fluid from a leak in one circuit, you don't lose it in both  :D

Ahem...

Clutch feed comes from just above MIN level so that you lose the clutch before you lose the inability to stop ::)

Issue is either failed slave or master, (or possibly a failed pipe/hose on either clutch or brakes).

If when you lift the pedal up, you get a single release from pressing the pedal, then the master has gone, otherwise it's either the slave or the pipe from the master. :-\

Yep,I reckon definitely hydraulic issue,if fluid is low then concentric slave,if fluid still full then suspect master,really unusual to have pipework fail unless fouled by something

No idea, clutch pedal has zero resistance, goes straight to the floor without doing anything

I had the same on the trafic I had....it was the slave cylinder....... ;)

Which is why I suggested checking fluid level .....

Lifting the pedal up should stop the flow to the slave, the level will only drop if it's actually leaking...

Does it drive if starting on the starter and then shifting by rev matching?

My daughter was amazed that you could do that when I drove her Seicento home after part of the clutch linkage across the bulkhead broke AGAIN  ;D

i did get it into gear like that at the traffic lights once, but stalled immediately, couldnt do it again to coincide with a green light. in a work car park now without room to test currently.

You need it in first and then start it, you have no chance with the engine running.

Is there any sign of wetness on the underside of the gearbox?

Slave cylinder then?

Can you pop the battery tray out for a closer look at the pipe work

Ive zero tools with me, emptied the car to shift furniture and havent refilled it yet.

Cannot shift the lid of the fluid tank.

IF i can get it off, and topped up, safe to drive home?
