T4 Post Icon Clutch master cyclinder

Hi all.

After years driving a type2bay, we have seen the light and brought a 2003 ex AA T4. After a damp patch appearing in the footwell, I installed a new master clutch master cylinder. But oil is dripping out from the solid feed pipe which you screw into the cylinder (left hand side of the cylinder). I guess maybe the thread is worn, but what is this pipe called, or where can you buy one from?

Any suggestions much appreciated!

Jeff

Feed pipe is the rubber/fabric hose from the reservoir to the master clyinder,its your pressure pipe thats leaking at the union.Try and nip it up and see if that stops the leak.A new pipe is available from VW or TPS if nipping it doesnt work.
You could make a new pipe using brake pipe but the unions on either end are different from brake pipe union so you will have to re-use the originals.

Hi Jeff.

You are a victim of the dreaded pedal box failure syndrome.

What you have had happen is that the pedal box has broken, this has caused your master cylinder to move out of alignment this has also caused the pipe to fracture. (common symptom,) it has fractured inside the nut so no amount of tightening will solve the problem.

As Aggie says VW or TPS for a new pipe ( approx 25.00)

To check your pedal box, stick your head into the footwell, press the clutch pedal with your hand while closely watching the master cylinder.
If there is ANY movement of the master cylinder then the pedal box is broken.

Another way to check it is to gently feel between the two bolts that hold the master cylinder to the pedal box, if you can feel a sharp edge or a crack then the pedal box is fooked.


Let me know if I can help.



Cheers Trev.

Cheers guys, the pedal seems solid, so I think it is the union nut. Sorry for sounding stupid, but what do you mean by nipping it?

Is it a bugger to replace the pipe/nut?

Thanks again Jeff

Care to take a bet that your pedalbox is still 100%?

The pipe is quite short it goes from the master cylinder through the bulkhead and into a joining nut just the other side of the bulkhead.

Oh and nipping it up means tightening it bit more than it already is

Cheers Trev.
