The Snap-On company carries several varieties of brake line double flaring tools manufactured by Blue Point. The flaring tool sets come in metric and standard, handling 4.75 mm to 10 mm or 3/16 to 1/2 an inch outside diameter brake line. The kit contains a flaring bar to hold the brake tube, a yoke and rod handle connected to a feed screw and flaring cone for flaring the line and five adapters for measuring the tube length and making the first flare on the brake line.
Instructions
- 1
Cut the brake line with pipe cutters. The cut must be straight across the brake line.
2Insert the tip of the inner/outer reamer blade into the brake line and twist it to remove the metal shavings inside the line. Turn the reamer over and remove the shavings from the outside of the brake line.
3Select the hole on the flaring bar that corresponds to your brake line diameter and insert the brake line into the flaring bar. Measure the length of the brake line with an adapter. The line should not exceed the height of the widened step at the bottom of the adapter.
4Tighten the wing nuts on the flaring bar to secure the brake line. Turn the yoke to the side so that it slides onto the flaring bar.
5Place the adapter so that the side with the pin fits inside the center of the brake line. Position the yoke so that the flaring cone sits in the center of the adapter.
6Turn the rod handle to tighten the feed screw and drive the flaring cone into the adapter. Stop when the adapter is pressed against the flaring bar. Loosen the rod handle enough to remove the adapter. The mouth of the brake line will be slightly belled. This is the first flare.
7Re-tighten the rod handle, pressing the flaring cone back into the brake line. Continue turning the handle until the cone stops. Do not exert too much force since this will cause the brake line to crack at the seams.
