    Took the zed out yesterday and strange the brake pad wear light stayed on on the dash. I had changed the pads and discs last year and don't do many more miles than Badman so I assumed it wasn't the pads.

    Took the brakes apart today to check the wear sensors and checked continuity on both and light still wouldn't go out. Decided to check the front again and gently pulled near the connector and found the break in the wires, must have just been touching enough to be ok for continuity but once flexed broke the circuit.

    Off to get a new sensor next week, I had tried to temporary solder it but soldering must be as good as my welding.

    At least I know what's wrong and the temp solder worked long enough to prove the light goes out on the dash.

    For a temporary fix you can just cut off the end of the cable, strip back the wires and twist together. I have noticed that a few times recently that the sensor cables have popped out of the pad, I then wonder why my light does not come on. :bashhead:

    Hi Brian Thought about doing that after I had put the wheel back on and then couldn't be bothered to take it off again.

    Usual problems with solder, not enough flux, not enough heat to melt the solder properly. Wrong type of solder also! HTH JIM

    Much easier to practice soldering than welding. Get yourself a butane powered soldering iron, some cored solder and a shed load of old wires of different sizes and practice.

    Got the new sensor today from BMW and cheaper than most on ebay or euro etc without discount so well pleased. Will fit it at the weekend.
