BRAKE LINE EMERGENCY REPAIR
Mopar preformed replacement brake lines are recommended and preferred for all repairs. However, double-wall steel line can be used for
emergency repair when factory replacement parts are not readily available.
Special, heavy duty tube bending and flaring equipment is required to prepare double wall brake line. Special bending tools are needed to avoid
kinking or twisting metal brake line. In addition, special flaring tools are needed to provide the inverted-type, double flare required on metal brake
lines.
Use Flaring Tool C-4O47, or equivalent, to provide the inverted, double flare. Heavy duty tube bending tools are available through the dealer tool
program.
Flaring Procedure
1. Cut off damaged tube with Tubing Cutter C-3478-A or an equivalent tool.
2. Ream cut edges of tubing to ensure proper flare.
3. Install replacement tube nut on section of tube to be repaired.
4. Insert tube in flaring tool. Center tube in area between vertical posts.
5. Place gauge form A over end of tube.
6. Push tubing through flaring tool jaws until tube contacts recessed notch in gauge that matches tube diameter.
7. Squeeze flaring tool jaws to lock tubing in place.
8. Insert plug on gauge A in tube. Then swing compression disc over gauge and center tapered flaring screw in recess of compression disc.
9. Tighten tool handle until plug gauge is seated on jaws of flaring tool. This will start inverted flare.
10. Remove plug gauge and complete inverted flare.
11. Remove flaring tools and verify that inverted flare is correct.
