3. After adjustment, inspect the pedal play.

Brake Pedal Play Inspection

1. Depress the pedal several times to release the vacuum in the power brake unit.

2. Gently depress the pedal by hand, and measure the pedal play.

Pedal-to-floor Clearance Inspection

1. Start the engine and depress the pedal with a pedal force of 147 N {15.0 Kgf, 33.0 lbf}.

2. Measure the distance between the pedal pad center and the insulator, and verify that it is as specified.
