Brake Hose/Line: Service and Repair

ISO Flare:

1. Obtain recommended tubing and steel fitting nuts of correct size. (Outside diameter of tubing is used to specify size.)
2. Cut tubing to length. You can determine the length needed by measuring the old pipe using a string and adding 3.2 mm (1/8 inch) for each ISO flare.
3. Install fittings on tubing before starting flare.
4. Chamfer the inside and outside diameter of tubing with the deburring tool. Then flare the tubing ends using an ISO flaring tool, such as J 29803-A. Follow the instructions included with the tool.
5. Carefully bend tubing to match old pipe. Clearance of 19 mm (3/4 inch) must be maintained between the pipe and all moving or vibrating parts.
