Cut brake lines to length and make up the fittings on each end. Putting bushings into inside of plastic lines with outside ferral can be frustrating. I have 2 that didn't want to go in all the way. Had to cut off and try again and finally got it in. Installed brake lines between cylinders as shown and then put pedal assembly into position in fuselage. Ran brake lines from mid section through tunnel to pedal assembly.
