Power Brake Unit Push Rod

  1. Adjust power brake unit push rod length before installing new master cylinder or power brake unit. Install master cylinder gasket. Place brake Master/Booster Push Rod Measuring Tool (SST 09737-00010) on gasket, and lower pin until it touches master cylinder piston.
  2. Without moving pin, invert master/booster push rod measuring tool, and set it on power brake unit. Measure clearance between power brake unit push rod and pin. Clearance should be zero. If clearance is not zero, adjust power brake unit push rod length until push rod lightly touches pin head.
