Release the parking brake pedal (pic. 1.140).
With the engine running, depress the pedal and measure the amount of pedal travel as shown.
Left hand drive vehicles: Pedal to floor travel at 490 N (50 kgf) - more than 63 mm.
Right hand drive vehicles: Pedal to floor travel at 490 N (50 kgf) - more than 70 mm.
If this is not the case, look for a malfunction in the brake system.
