How do the brake lights?

I have been working on the lights, got the flashers, turns signals, but the Brake lights are a problem. The diagram should show how it should work, as the picture are not of all. It is true that Brake has a white wire from Brake switch to white to Brakes, I was told that the left has a yellow wire, the left side rear, it should combine the lights and separate for park. The same as on the right rear, only it has a white wire tight to light green wire and park green wire.

There is a orange sw brake, I have never messed with that wire. I did the wiring about 7 years, I had pulled the body this year for modifications. Everything works except the brake lights. Another thought, I notice a steel brake line seems to a loose fitting, I have been driving, I have notice any leaking.

I have been working in the garage for two days, it is cold, I have a heater, but it is not the best to way to get a cold.

You need to determine if the rear turn signal bulbs are used for the brake lights.
This is the most common setup.
The diagram you posted indicates that the rear turn signals are separate from the brake lights.
If this is the case then just check for battery voltage at the brake light switch. Then check for voltage with the brake depressed. Of course, make sure the bulbs are good and the grounds are solid.
The attached diagram shows a typical arrangement for turn signals and brake lights combined.

Your white wire is the main feed to the rear brake lights. You also have a brown wire that ties into the line which feeds your reverse or backup lights. There may a problem with the brown wire interfereing with the brake lights. I'm assuming your running a mechanical brake switch and not the hydraulic that runs off pressure within your brake line. The mechanical, you need to make sure the switch is depressed when you apply the brakes. Sometimes the switch will move or is not adjusted properly, allowing the switch to no activate as the pedal is depressed. If your running a pressure switch, sometimes you don't have enough brake line pressure to activate the switch and may have to install a switch that will activate with less pressure.

Thanks for the experts

The diagram I had and still to understand it of too simple, yet, the Newer I printed out is too over my head. I am a tech writer, I am not a electrical engineer. I will look on the new diagram in the morning.
Check the 40 ford coupe, I ran a 305 with saginaw 3 speed with overdrive. The overdrive leaked and the 305 shucked the skirts on a piston. Finish of MMII with 5.1/2" with 16" cokers and a 500 cadillac and a TH400. The Caddy is very quiet, the 305 was radical. Take a look of pictures on profile. I am fraid to push the throttle.

How do the brake lights-Proportioning Valve

Hey guys,

I remembered about the Proportioning Valve, loose line to the rear valve. I remembered when I went to go to alignment at shop, I was scared to go up on the rack. The guy was calling me to keep moving. What he didn't know, the rear brakes were not working. The front brakes were working, if that front brakes didn't, it would take off and hit the guy. I took very easy. The proportioning rear valve is stuck per a little ball in there. I was told by a mechanic, lift the rear off the ground. Let it run foward and back to try to apply the brakes till stop and try back. Some times need to have a hammer to hit the valve.
The brake fluid was going in the rear of the valve, but shut by the stuck ball.
I tried the charger on the switch, nothing happened. There are no fluid to the switch. I was fighting with the wires, they are right. We just didn't notice the fluid not having of the valve.

I just want to fix the Valve to the rear, it is stuck. Hydraulic fluid cannot to enter the lines past to the brake switch. Do you know about how it works and how to release the little ball in the Valve?

You are right, but they take our writing, run in a translation software. The steps don't make sense but people are starting to pictures to because nobody does no english.
