Run the engine at idle after warming up the engine, and depress the brake pedal with a force of 500 N (51 kgf, 112 lb). Measure the distance between
the brake pedal and steering wheel. Release the pedal, and measure the distance between pedal and steering wheel again.
Specification of pedal stroke: When depressing the pedal with a force of 500 N (51 kgf, 112 lbf). 95 mm (3.74 in) or less
11) If the distance is more than specification, there is a possibility of air being caught in the brake line. Bleed the brake line of all air until the pedal
stroke meets the specification.
12) Operate the hydraulic control unit in the sequence control mode.
13) Check the pedal stroke again.
14) If the distance is more than specification, there is a possibility of air being caught in the hydraulic unit. Repeat above steps 2) to 9) until the pedal
