Power Brake Unit Push Rod

WARNING: This page is about a different car, the 1996 Lexus SC 300 and 1995 Lexus SC 300. However, it is still accessible from the selected car via links, so may be relevant.
  1. Adjust power brake unit push rod length before installing new master cylinder or power brake unit. Install master cylinder gasket. Place 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.
