I have a 06 f150, and just went to start it when i noticed the brake pedal was as hard as a rock. I nursed her home and the called the local ford shop. I am going to have my Booster vacume hose replaced (recalled), but was wondering if i may have done any more damage by driving it home. I dont know how much more stress is put on the brakes once that goes out but i know it didnt feel good.
