Procedures
STANDARD PROCEDUREDOUBLE INVERTED FLARING
A pre-formed metal 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 double inverted flares or ISO flares.
1. Cut off damaged tube with a Tubing Cutter.
2. Ream the cut edges of the tubing to ensure a proper flare.
3. Install the replacement tube nut on the tube.
4. Insert the tube in the flaring tool.
5. Place the gauge form over the end of the tube.
6. Push the flaring tool through the flaring tool jaws until the tube contacts the recessed notch in the gauge that matches the tube diameter.
7. Tighten the tool bar on the tool.
8. Insert the plug on the gauge in the tube. Then swing the compression disc over the gauge and center the tapered flaring screw in the recess of the compression disc.
9. Tighten the tool handle until the plug gauge is squarely seated on the jaws of the flaring tool. This will start the inverted flare.
10. Remove the plug gauge and complete the inverted flare.
ISO FLARING
A pre-formed metal 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 double inverted flares or ISO flares.
To make an ISO flare use Snap-On Flaring Tool TFM-428 or equivalent.
1. Cut off the damaged tube with a tubing cutter.
2. Remove any burrs from the inside of the tube.
3. Install the tube nut onto 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 the yoke screw over the tube.
8. Turn the yoke screw in until the adapter is squarely seated on the tool bar.
