SOURCE: Brake pedal won't return.
There could be a couple reasons for this. First thing to check is your return spring, is it still there and attached properly? Next thing to check is your master cylinder pressure release. Loosen the bleed nipple on the rear caliper. Does the brake release now? If so, your master cylinder has some debris clogging the fluid return passageway. Remove and clean it. If the brake still does not release after opening the bleed nipple, at least one of your caliper pistons is binding. Remove the rear caliper and the brake pads. Now press the pedal and force the pistons out. Looses the bleed nipple and attempt to press the pistons back into place. They should move smoothly when you apply firm pressure. Clean the caliper thoroughly. If you have a rebuild kit for the caliper this is a good time to rebuild it. After cleaning, put it back together, bleed the brakes and test again. It is normal for disk brakes to drag SLIGHTLY on the rotor, but they should not stop a free spinning wheel in less than a coupld revolutions when spun by hand.

Not too hard - Undo the two bolts on the caliper and then seperate the caliper and pull the old ones out. Insert the new ones and put the bolts back in to hold the caliper back together and then install them back on the bike with the two retaining bolts. Use a bit of lock tight (Blue) on the threads. Warning do not let anyone apply pressure on the brakes while you have them off the bike or you will have a mess and/or a problem.
SOURCE: Rear brake light not workiing
There are two brake light switches. One is in the right handlebar switch housing. This is front brake light switch and is a simple push button type switch actuated by the front brake lever.
The other switch is a pressure switch and it is located in a Tee usually somewhere under the bike near the rear of the transmission. Follow the metal tube coming out of the rear of the master cylinder. It will go back towards the rear brake. Somewhere in that line there will be a tee with the pressure switch in it. If you jumper across this switch, the brake light should work. If it does work when you do this but not work when you depress the rear brake signal, replace the rear brake light switch.
Good luck

Sorry but I don't have a wiring diagram that I can send you but I may can offer a bit of help.
Your passing lamps are simply wired into a hot circuit somewhere. A lot of schematics don't show them because they are considered "add ons". They also may have a fuse inline with the "hot" wire. They have only one wire that connects them to the bike with the rest being inside the "light bar" itself. Find the wire coming out of the center of the "light bar" and trace it back to where it hooks up. Sorry but that's the best I can do on this one.
On your front brake light, there is a switch located inside your right hand switch housing where your throttle is located. It is a plunger type switch that is activated when you pull the front brake lever. A simple test of the switch is to loosen the bolts of the master cylinder and slide it towards the center of the handlebars. If the switch is good, the brake light will come on. If the switch is bad, it will not.
To get to the switch, you'll have to take the right hand switch housing apart. First, loosen the throttle cables at the adjusters and then remove the two bolts that hold the switch housing halves together. Carefully open up the switch housing. You will see the small switch in the front of the housing. You'll have to desolder the wires, replace the switch with a new one, and resolder the wires to the new switch.
Reassembly is the reverse of the disassembly. Make sure you slide the master cylinder all the way back against the switch housing or the brake light will stay on constantly. Readjust the throttle cables and check for proper operation. You don't want your throttle sticking.
Good Luck

It sounds like the rear brake pressure switch is bad. The wires for the front brake light switch are wired in parallel to the this switch. Replace the pressure switch in the metal brake line coming from the rear brake master cylinder going to the rear brake caliper.
Good Luck
