can anyone tell me what the light next to the handbrake is for? it has been on for the past month or so now (cab very rarely gets driven) and sometimes flickers when i go over a bump, was wondering what it could be for and how to get it off, its the one next to the handbrake light on the right hand side.
thanks in advance guys.

brake wear sensor

take it it requires new pads then or discs too?
cheers matey.

Check the sensor cable first, might have come loose. Two pin plug on the inside of the wheel, near calipers. Can't remember if they are on all wheels, but defo on front passengers, and rear drivers.

This was my problem, MOT guy must have caught it when he was fumbling around!!

Check the pad wear sensor(s) first, and if they, and their connections, are OK, then it is possibly a common and easily repaired fault inside the instrument cluster.

Brian,

Can you give a bit more information on the "common and easily repaired fault inside the instrument cluster"?
A friend asked me about this recently and his brake pads and wear sensors are new and the brake wear circuit looked complete.

Thanks,

There is a small rectangular lump in the back casing of the instrument cluster, roughly behind the top of the temperature gauge. The soldered joints of the component inside this lump become cracked or "dry jointed"
Remove the cluster from the car, unscrew all the hex screws on the back, ( NOT the two nuts - tighten these), and carefully seperate the two halves of the cluster.
On the back part, nearly hidden by the temp gauge, you will find the two cracked solder joints. Just resolder them, one at a time, (or the copmponent may fall out), with a little new solder.

Thx Brian, 'will pass this on,

I have also had a problem with corroded contacts in the plug/socket of the brake pad wear sensor. The one which is slotted onto the plate.
