Symptoms of Master Cylinder Failure

Do the Job Right

• Bench bleed Master Cylinder before installation
  All air must be removed from the master cylinder using the bench bleed method. Failure to do so is the #1 cause of failure and may result in spongy or low brake pedal; this will void the warranty. Use bleeder kit supplied.

• Use a wooden dowel or blunt tool
  Use only a dowel or blunt tool during bench bleeding. Sharp or metal tools can cause damage to the master cylinder piston and bore.

• Flush entire brake system before installation
  Removing all air, dirt and contaminants from system before installing master cylinder helps prevent premature brake system failure.

• Use approved/new brake fluid

  1. Use only brake fluid recommended on the reservoir lid, owner’s manual, or service manual. Never use petroleum-based fluids, or mix fluids
  2. Always use new brake fluid from a sealed container. Reusing old brake fluid will return contaminants and moisture to the system which can cause premature system failure.

   

• Inspect entire brake system
  Inspect the entire brake system before replacing parts. Replace cracked or extremely corroded lines.

• Follow CARDONE’S easy-to-read instructions
  Follow the step-by-step, fully-illustrated instructions included with every unit. ALSO follow any specific instructions provided by vehicle manufacturer.
