1stly I need to know if this light being on classes an an MOT failure?
secondly it came on 2 days after I bought the car and has not gone off since. I have replaced the front brake pads, as they were low and the front wear sensor and the light has not gone off.
I had the car checked by the garage before changing the pads and they told me the rears were fine, however I've not checked this myself.
I do have a set of rear pads I can put on but if this does not sort it then I'm gonna look at a new rear pad wear sensor but again if that does not sort it where should I look next?
How does it work if the light is on does it mean the circuit is broken and therefore could it be a frayed/broken wire somewhere else?
