If less than one inch, two things must be examined:
Free Play:
Free play of the brake pedal should be 1/8 - 1/4
inch (3.2 - 6.35 mm).
If free play is excessive, inspect pedal, linkage, and
master cylinder for wear or damage and replace any
parts as needed.
Bleeding:
If free play is correct and brake pedal travel is still
excessive, air may be trapped somewhere in the
system. Bleed the hydraulic auxiliary brake system in
a conventional manner, following the procedure
outlined in Brake Chapter 9.
