I unrolled
2-pieces of ¼" aluminum tubing to fabricate the left and right brake
lines. I straightened the tubing by
cutting it to length and using a piece of 1x4 plank I rolled the tubing on the
work bench. Both pieces came out pretty
straight. I then used the flaring tool
to flare one end of each tube. I then
installed the fittings and flared the other end. The brake lines a now ready to be bent and
installed on the airplane.
