Clutch Pedal - No Resistance

[Krillo]

Hi all,

My van has been sitting all winter, and the other day I did a little check-up on it.
The clutch pedal is no longer clutching
The hydraulic / break fluid was very low, filled it up. No change.
The pedal feels like nothing exept the return-spring is attached.
Could this be merely air getting into the system, or could it be something else?

Thanks

Mein Transporter hat den ganzen Winter über gestanden, und neulich habe ich ihn einer kleinen Kontrolle unterzogen.
Das Kupplungspedal kuppelt nicht mehr
Die Hydraulik-/Bremsflüssigkeit war sehr niedrig, und ich habe sie aufgefüllt. Keine Veränderung.
Das Pedal fühlt sich an, als ob nichts wäre, außer dass die Rückholfeder befestigt ist.
Könnte es sein, dass lediglich Luft in das System gelangt, oder könnte es etwas anderes sein?

Hi Krillo,

first you have to check for a leak under the car. May be, the clutch line from front to transmission is broken from rust. I had that problem years ago on my van.
Have a look for drops under the car and along the line and clutch cylinder.
When fluid is low there must be a leak somewhere.
Check it and than write again.

Best regards, Gerd

It was the slave cylinder.

I suspect I will have to make one myself, but does this short hydraulic line have a original part number?

Ich vermute, dass ich sie selbst anfertigen muss, aber gibt es für diese kurze Hydraulikleitung eine Originalteilnummer?

Thanks

It defends to the type of make.

The hydraulic clutch tube is of 6 mm outer diameter brake line or a plastic tube (like pneumatric hose).

It is likely to be changed against a pressure hose like that: https://tk-carparts.de/kupplungsleitung ... 721477j-jp

So this is the story from beginning to end.
The slavecylinder began to leak, slowly draining the system of brakefluid. When I noticed where the leak was, I ordered a new slave cylinder. Once I started removing parts, it became clear that I needed to replace the flexible hose and the steel line going to the front of the van, rust had made the parts impossible to take apart, except for the junction at the front of the van.
JP Group makes replacement lines, but no longer have any official distributor in Sweden. I emailed JP Group who got me in contact with Utzon in Sweden who kindly supplied me with the flexible hose 1131000200, VW Nr.: 251721477J and steel line 1131000400, VW Nr.: 251721471B.

Things have been moving slow, but at least it's all taken care of now.
