2.Operate the pedal by hand,
and check that the pedal stroke (free play) meets the
standard value at the point where resistance is
felt. Standard value (B): 3 mm or
less 3.If the brake pedal play is not
within the standard value, check the following, and adjust
or replace if necessary:
- Excessive play between the brake pedal and the
