Hi, managed to change discs, pads and callipers on both front wheels. Bled the system but ono starting both the DSC light and brake light are both remaining lit. I took the car for a test drive and it is driving like it should no more rattling, the lights remained on though, I checked the brake fluid which was low, refilled but lights still remain. do I need to reset these or should they have gone out? any ideas please?
