Follow the brake line from the rear of the rear brake master cylinder until you get to a round metal thing with two wires attached to it screwed into a Tee fitting. This is the rear brake light switch.

SOURCE: how to replace front brake

Just take your old line off and replace it with the new line. Be careful because the brake fluid will damage your paint if it's DOT 4. One you have replaced the brake line, fill the master cylinder with the proper brake fluid. Open the bleeder valve and let gravity do it thing. Usually once the fluid starts to flow out of the bleeder valve, all the air is gone as well.

But if the brake lever still feels spongy or no brake at all, first bleed the master cylinder. Squeeze the hand lever and hold it while you loosen the union bolt on the end of the master cylinder. Once the pressure bleeds off, close the valve and repeat the process until you get no air bubbles. Then, move down to the brake caliper and do the same thing until you get no air and a full brake lever. You must do it in this order exactly. Squeeze the lever, open the valve, close the valve, let go of the lever. Do not allow the master cylinder to run dry during the bleeding process.

Good Luck
