Removal & Installation



Except SRT-8
  1. Disconnect and isolate the negative battery cable from battery post.
  2.  
  3. Using a brake pedal holding tool, depress brake pedal past its first inch of travel and hold it in this position. Holding pedal in this position will isolate master cylinder from hydraulic brake system and will not allow brake fluid to drain out of brake fluid reservoir while brake lines are open.
  4.  
  5. Disconnect the brake tubes from hydraulic control unit.
