The brake pad wear indicator light came on after over an hour on the road the other day and it's come on several times since, only after long periods of driving. I live on a mountainous island, so driving here involves a lot of braking down hills and around corners. The manual recommends that you have the brakes checked as soon as possible when the light comes on, but how long do you probably actually have before the pads are completely worn? Is it ok to drive until I can get the car in, maybe in a week or so, or should I try to get it in asap?
