Brake Pedal Travel

NOTE: Brake pedal travel is not adjustable. Use the following procedure to determine if brake pedal travel is as specified.

Most low brake pedal or excessive pedal travel problems are caused by air in hydraulic system. Bleed hydraulic system before continuing procedure. See BLEEDING BRAKE SYSTEM . Other possible causes of excessive pedal travel are incorrect power booster pushrod length, parking brake adjustment, frozen rear brake shoe adjustors, worn linings, or a leak in hydraulic system.
With engine off, pump brake pedal until all vacuum reserve is exhausted from power brake booster. A definite change in pedal feel will occur. Install Brake Pedal Effort Gauge (J-28662) onto brake pedal. Hook end of tape measure over top of brake pedal. Measure and record distance to rim of steering wheel.
Apply 100 lbs. (45 kg) of force to brake pedal. Measure and record distance to rim of steering wheel again. Difference between measured values is brake pedal travel. If brake pedal travel exceeds specification, adjust rear brake shoes. See BRAKE PEDAL TRAVEL SPECIFICATIONS table. See REAR BRAKE SHOES.
