J and K AUTOMOTIVE TOWING AND REPAIR 2/14/2011
Look on the rear side of the brake pedal. There is a cotter pin on the end of the brake pedal to pushrod retaining pin. Grab the end of this cotter pin and pull it straight out.
Use a punch or a small screwdriver to gently tap the brake pedal to get the pushrod retaining pin out of the mounting bracket.
Separate the brake pedal from the pushrod by pulling up on the brake pedal.
