Hi all, I've got an intermittent brake pad light coming up on the dash. New abs unit and brake pads in last few months so likely not that. How can I find out what it is with my multimeter? I've cleaned up the earths on the wear cable as these were awful! |

I'd have a good look at the cables and make sure they're not cut/damaged anywhere 1st. |

What's the method for checking the wire? I assume if I pull out the wear cable from the connector i can test both the cable, and the connections to the fuse box in the same process? If I connect my mulitmeter to the end of the wear cable am I looking for a continuous circuit with the cable? What should I be looking for with the connector box? Assume I'm looking for 12v? (i.e. where the wear cable plugs in) Thanks all. |

The wear indicators are a wire loop. WHen the pad runs out it wears the loop & then breaks the wire. TBH on a well maintained car I would bin then & loop them out. Which is what I did with mine. |

Thanks, I understand that they break their circuit when they wear. All my pads and discs are new and i've renewed the earths on the abs / wear cable unit. How can i check the cable and rule this out with a multimeter? And similarly how can i check the other wiring. Fault is intermittent but light is on 80% of the time. |

if you have had all the sensors out of the plastic blocks make sure they are all clean and good contacts inside. a crusty pin would cause a problem also im not sure they need to be broken just grounded out is enough i think |

Did you change the sensors or at the very least clean them? |
