Step 1: Determine the Brake Line Routing With a Wire
Determine the fittings and banjo bolt sizes you will need for the master cylinder and caliper.
This is for a 2003 Sportster. The master cylinder on the left takes a 20 degree 7/16" banjo fitting and the caliper on the right takes a 90 degree 3/8"/10mm banjo fitting.
Using a piece of wire or thin rope, route the wire in the fashion of how you will be routing the brake line. Then, while holding the end of the wire, lay it out on a workbench and measure the length with a tape measure.
NOTE: If you are doing a front brake line be sure to leave enough length for the handlebars to turn left and right freely with no tension.
Todd taking an old cloth wire laying around the shop and routing it along the bike how he feels the brake line would look best. Routing from the master cylinder mounted on the handlebars to the caliper on the bottom legs.
After pinching the line at the desired length, Todd took it to the workbench and laid it flat. He then marked each end on the surface and then used a tape measure to determine the length of brake line he will need.
Step 2: Start to Replace Brake Line From The Master Cylinder
Install your fittings on the motorcycle master cylinder and caliper, be sure there is a sealing washer on each side of the fitting. The order it should go in, Banjo bolt, sealing washer, fitting, sealing washer, caliper or master cylinder.

Step 3: Install the Brake Line to the Fitting
Install your brake line to each fitting. Make sure everything is tightened accordingly and run the way you want. Reuse stock mounts or find a way to mount each line so it is not in the way of getting snagged or pinched.
Installing brake lines is easy, just screw them on to the banjo fitting ends and tighten.
Step 4: Fast-Fill Up Master Cylinder and Your Bike Is Ready
Fill up the master cylinder with the correct brake fluid required by the recommendations of your motorcycle. Note that there are DOT 3, DOT 4 and DOT 5 brake fluids, and you should not mix them!
Bleed the brake line using a brake bleeder. Check for any leaks, test that the brake works and GO FOR A RIDE!
This 2003 sportster takes DOT 5 brake fluid. Do not mix different brake fluids use what your bike recommends. Todd used an air bleeder to help bleed the brakes.
NOTE: After doing any work on your brakes, be sure to always test that they work properly and that the bike wheel stops properly before going for a ride. You can jack the bike up and spin the wheel, apply brakes to see if it stops. If on the ground, just push the bike and hit the brakes to ensure that it fully stops and that the motorcycle brake lever or pedal feels firm.
After brakes are bled you will feel the brake lever harden. Make sure brake fluid is filled before putting the cover back on. Be sure to test the brakes before going for a ride.
