3. Measure the clearance between the brake booster push rod and accessory tool.

   Standard Clearance

   0 mm (0 in.)

   HINT: 

   Adjust the clearance in the following cases:

   • If there is clearance between the accessory tool and the shell of the brake booster (the accessory tool does not contact the body of the brake booster), the push rod is protruding too far.
   • If the chalk does not stick on the tip of the brake booster push rod, the push rod protrusion length is insufficient.
4. If the clearance is not as specified, adjust the push rod length by holding the push rod using SST and turning the tip of the push rod using a 7 mm socket driver.
   • SST: 09737-00020
