HINT:

Measure the distance at the same point used for the brake pedal height inspection.

1. Release the parking brake lever.
2. With the engine running, depress the brake pedal and measure the pedal reserve distance as shown below.

   Pedal reserve distance from the tibia pad at 500 N (51 kgf, 112 lbf): 84.4 mm (3.32 in.) 

   If the distance is not as specified, troubleshoot the brake system (See PROBLEM SYMPTOMS TABLE  ).
