Shut off the engine and depress the brake
pedal about 10 times strongly, then check
the brake pedal for free play by lightly
pushing it by hand until you feel resistance.
Next, start the engine, and wait at least 1
minute. Then depress the brake pedal and
measure the clearance of the pedal from
the floor (that is, the distance between the
