Please would someone be able to say what this small green tube is. It appears to be going to the brake callipers on the front near side ( passenger side ).

There does not seem to be an equivalent on the front Off side ( Drivers side ).

I noticed it was badly kinked and may even be torn. I’ve done a running repair for the time be but am concerned about having a developing problem as I’m off on to Cornwall on Friday ( 500 miles return ).

Any advice much appreciated.

Pad wear sensor wire. They’re about 20 quid for a new one and plug into the black plastic box in your picture then are a push fit with a small metal clip on the brake pad, they are on one side only hence o/s missing

Thanks @Diesel-Dave. Is the green tube a protective sheaf or is that the whole thing ? It seems so flimsy that I wonder if there is a electrical wire inside the PVC tube. TDV8 4.4 2012

Wire inside, once pad wears down to the wire, it goes open circuit and brings in your dash light

The green sheath is the whole thing.

Yes its a protective cover, there is a wire in there but its only a sensor wire, IE when the sensor on the pad touches the disk the ECU gives you a message you have worn pads. I never like to say you’ll be ok to leave it with brakes, however the worse you could get is a false worn pads warning, or none at all if broken then the pads touch the disc with a scoring noise as in the old days.

Thanks everybody; I’m feeling reassured! TDV8 4.4 2012

Mine was fine with one of the sensors off for about a month - no warning light or anything.
