How does brake pad warning light work?
I've just come out from working on a local companies computers to find on driving, when the brake is slightly applied, the brake pad wear light flickers as the wheel goes round (only seems to come on at one place in the wheels rotation at the moment). To see if it's front or rear, I tried pulling the handbrake while driving - no light. This implies it's front brakes, but I only changed the front pads around 6,000 miles ago, how long should they last??
As I remember from when I installed them, they'll only warn of wear on the pads, not the discs, is that true?
Is the light supposed to come on only when applying the brake, or does it stay lit permanently?
