My Brake pad warning light just came on, How long till they are useless? They look like they still have around 5-8mm left I dont get paid for 2 more weeks and a bit short on funds, to book it in to get them replaced. Am guessing i can still drive but taking it easy to work and back, its not even a 5mile drive there and back. If the worst comes then i guess ill be walking to work. Also will it be worth changing the discs at the same time?
