ISO Flaring

STANDARD PROCEDURE - ISO FLARING
A performed metal brake tube is recommended and preferred for all repairs. However, double-wall steel tube can be used for emergency repair when factory replacement parts are not readily available.

Special bending tools are needed to avoid kinking or twisting of metal brake tubes. Special flaring tools are needed to make a double inverted flare or ISO flare.
To make a ISO flare use Snap-On Flaring Tool TFM-428 or equivalent.
1. Cut off damaged tube with Tubing Cutter.
2. Remove any burrs from the inside of the tube.
3. Install tube nut on the tube.





4. Position the tube in the flaring tool flush with the top of the tool bar. Then tighten the tool bar on the tube.
5. Install the correct size adapter on the flaring tool yoke screw.
6. Lubricate the adapter.
7. Align the adapter and yoke screw over the tube.
8. Turn the yoke screw in until the adapter is squarely seated on the tool bar.
