I feel like I'm never done asking advice.
The latest drama is this. Driving to work this morning the brake pedal felt like it was biting at a much higher point. When the brakes were applyed very gently the car pulled to the left and it felt like ABS kicked in. I went on another 100yds or so and braked again. Same deal. Pulled over and let some poo out before having another go. This time all three light, ASB, low tyre pressure and ESP dash lights came on and brakes seemed to work as normal again. Any clues?
