Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Caution: Always use double walled 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 cause brake system failure.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.
Important: When servicing the brake pipes, note the following:
-
If sectioning the brake pipe, use replacement pipe of the same type and outside diameter.
-
Use fittings of the appropriate size and type.
-
Only create flares of the same type or design as originally equipped on the vehicle.
1. Inspect the area of brake pipe to be repaired or replaced.
2. Release the brake pipe to be replaced from the retainers, as required.
3. Select an appropriate location to section the brake pipe, if necessary.
-
Allow adequate clearance in order to maneuver the J 45405.
-
Avoid sectioning the brake pipe at bends or mounting points.
4. Using a string or wire, measure the length of the pipe to be replaced including all pipe bends.
5. Add to the measurement taken the appropriate additional length required for each flare to be created.
