WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Before proceeding, refer to Brakes - Warning and Brakes - Caution .

  2. Using a brake pedal holding tool as shown in the illustration above, depress the brake pedal past its first 25 mm (1 inch) of travel and hold it in this position. This will isolate the master cylinder from the brake hydraulic system and will not allow the brake fluid to drain out of the master cylinder reservoir while the lines are disconnected.
  3. Remove the engine appearance cover.
  4. Loosen lower and upper mounting nuts, then remove the exhaust heat shield from the dash panel.
  5. Pull the brake tube bundle routing clips (with tubes) loose from studs on the dash panel.
