1. Visually inspect all of the brake pipes for kinks, improper routing, missing or damaged retainers, leaking fittings and excessive corrosion. 2. If any of the brake pipes exhibited any of the conditions listed, then the identified pipe, or pipes, require replacement. See BRAKE PIPE under REMOVAL & INSTALLATION. 3. Ensure that the vehicle axles are properly supported at ride height in order to maintain the proper relationship of the flexible brake hoses to the chassis. 4. Visually inspect all of the flexible brake hoses for kinks, improper routing, twists, chafing, missing or damaged retainers, leaking connections, cracking, dry-rot, blisters or bulges. 5. If any of the flexible brake hoses exhibited any of the conditions listed, then the identified flexible brake hose, or hoses require replacement. See BRAKE HOSE under REMOVAL & INSTALLATION. 6. Squeeze the flexible brake hoses with firm finger pressure to check for soft spots, indicating an internal restriction. Check the entire length of each flexible brake hose. 7. If any of the flexible brake hoses were found to have soft spots, then the identified flexible brake hose, or hoses require replacement. See BRAKE HOSE under REMOVAL & INSTALLATION. BRAKE PEDAL TRAVEL MEASUREMENT & INSPECTION 1. With the ignition OFF and the brakes cool, apply the brakes 3-5 times, or until the brake pedal becomes firm, in order to deplete the brake booster power reserve. 2. Install the Brake Pedal Effort Gauge (J-28662) to the brake pedal. 3. Measure and record the distance from the brake pedal to the rim of the steering wheel; note the points of measurement. See Fig. 7 . 4. Apply and maintain the brakes with 100 Lbs. (445 N) of force to the brake pedal, as indicated on the brake pedal effort gauge. 5. While maintaining 100 Lbs. (445 N) of force to the brake pedal, measure and record the distance from the same point on the brake pedal to the same point on the rim of the steering wheel. 6. Release the brakes and repeat steps 4 and 5 to obtain a second measurement. After obtaining a second measurement, proceed to next step. 7. Average the first and second measurements recorded during the 2 applies of the brakes. 8. Subtract the initial measurement, un-applied, from the averaged, applied measurement to obtain the brake pedal travel distance. For hydraulic assist equipped, maximum brake pedal travel (measured with the thoroughly with water. In case of skin contact, wash with soap and water. CAUTION: Avoid spilling brake fluid onto painted surfaces, electrical connections, wiring, or cables. Brake fluid will damage painted surfaces and cause
