- Obtain the recommended tubing and steel fitting nuts of the correct
size. Use the outside diameter tubing in order to specify the size.
- Cut the tubing to length. Determine the correct length by using
a string in order to measure the old pipe. Add 3 mm (1/8 in)
for each ISO flare.
- Before starting the flare, install the fittings on the tubing.
- Chamfer the inside and outside diameter of the pipe with the de-burring
tool.
- Remove all traces of lubricant from the brake pipe and the flaring
tool.
- Clamp the flaring tool
body in a vise.
- Select the correct size collet and forming mandrel for the pipe
size used.
- Insert the proper forming mandrel into the tool body.
- While holding the mandrel in place with a finger, thread the forcing
screw until the screw makes contact with and begins to move the forming mandrel.
- When contact is made with the forming mandrel, turn the forcing
screw back one complete turn.
- Slide the clamping nut
over the brake
pipe into the correct collet. Leave approximately 19 mm (3/4 in)
of tubing extending out the collet.
- Insert the collet into the tool body. The brake pipe end must
contact the face of the forming mandrel.
- Tighten the clamping nut into the tool body very tight or the
pipe may push out.
- Wrench tighten the forcing screw until the screw bottoms. Do not
overtighten the forcing screw or the flare may become oversized.
- Back the clamping nut out of the tool
body.
- Disassemble the clamping nut and collet. The flare is now ready
for use.
- Bend the pipe to match the old pipe. Maintain a clearance of 19 mm
(3/4 in) for all moving or vibrating components.
