So brake pad warning light came on yesterday. Visual inspection suggests they're all good, I haven't noticed any decrease in braking performance, and the discs aren't marked outside/inside that I can see. All of the brakes were changes <3000miles ago (all new calipers / pads / discs) and I don't tend to be particularly heavy on the brakes. All of this leads me to conclude its a sensor issue. I've had the car up and had a look at the connections on the front pair which appear to be in place and properly seated, but the error light persists. Anyone got any ideas or quick fixes that can sort the error light issue?
