There are two bolts that hold the rear caliper into the rear caliper bracket. Remove these two bolts and the caliper lifts out of the bracket.

Notice how the pads and the anti-rattle hardware is positioned in the bracket. Replace the pads and hardware making certain that you get the fiber side of the pads against the brake rotor.

Now, you must get the piston back into it's bore. I use either a large C-clamp or a large pair of slip joint pliers to press the piston back into it's bore. Use rags or thin pieces of wood to protect the finish on your caliper.

Once the piston is completely pressed into it's bore, carefully replace the caliper back into the bracket without disturning the pads. Slowly depress and release the rear brake pedal until you get a full firm pedal. Test the brakes before you ride the bike. Failure to properly service the brakes on your bike can result in serious injury or death. Make certain that you do this job correctly or take to an experienced person to have it done. If your bike quits it makes you mad, if it won't stop, it hurts you.

Ride safe.

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

Take the two bolts out that hold the caliper into the caliber bracket. Look at the pads and the anti-rattle hardware and make sure you know how it all goes in there. Remove and replace the pads and hardware.

You'll have compress the piston back into the caliper. I use either a large C-clamp or a large pair of slip joint pliers to compress the piston. Use a rag or a couple of pieces of wood to protect the finish on your caliper.

Once the piston is completely compressed into the caliper, carefully reposition it onto the caliper bracket. Install the two bolts and torque them to 20 foot pounds. Step on the rear brake slowly several times until you get a full firm brake pedal. Test the brakes before you ride the bike.

Good Luck
