Servicing front brakes
  Note
t  Install all parts supplied in repair kit.
t  After replacing brake pads, depress brake pedal firmly several times with vehicle stationary so that the pads are properly seated in their normal operating position.
t  To draw off brake fluid from brake fluid reservoir use a bleeder bottle which is used only for brake fluid. Brake fluid is poisonous and must on no account be sucked out with the mouth using a hose!
t  When renewing brake components (brake discs, brake calipers or brake pads), always make sure you install the correct parts for the vehicle. This is essential for the proper function of the ESP.
