Caution: Always use double-flared steel brake pipe when replacing brake pipes. The use of any other pipe is not recommended and may cause brake system failure. Carefully route and retain replacement brake pipes. Always use the correct fasteners and the original location for replacement brake pipes. Failure to properly route and retain brake pipes may cause damage to the brake pipes and lead to brake system failure.

Important: Maintain a 6 mm (1/4 in) clearance between parallel brake pipes.
