In preparation for my MOT tomorrow I gave the car a quick once over last week. Took the pads out greased all the slider bolts and guides and some on the pads to stop the squeal I was getting. When I got to the front pads they had hardly any wear on them. I noticed the low pad warning wire had been rubbing and was through the sheathing, but still working fine. Today the low pad light came on! I know what has happened, the stripped wire has shorted itself on the calliper and induced the warning light. Its intermittent, but what happens if it comes on in the MOT test tomorrow morning? I will tell the Tester the pads are nearly full, but is it a fail if a warning lamp comes on in the dash? Any qualified advice most appreciated.
