  2. Using a brake pedal holding tool as shown in illustration, 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.
