Welcome to the RHDJapan Blog. When upgrading brake lines and rotors brake fluid is also required. This campaign will allow the user to completely bleed the system with some fresh Dot 4 brake fluid from APP. This will ensure optimum braking performance! The purchase of any set of Brake Rotors or Brake Lines from APP will qualify for a 100% discount on the brake fluid. (shipping cost must be covered if not consolidated).
