WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Brake fluid may irritate eyes and skin. In case of eye contact, rinse thoroughly with water. In case of skin contact, wash with soap and water. If ingested, consult a physician immediately.
CAUTION: Avoid spilling brake fluid onto painted surfaces, electrical connections, wiring, or cables. Brake fluid will damage painted surfaces and cause corrosion to electrical components. If any brake fluid comes in contact with painted surfaces, immediately flush the area with water. If any brake fluid comes in contact with electrical connections, wiring, or cables, use a clean shop cloth to wipe away the fluid.
  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.
