On our cars, the stop circuit goes thru the turn signal mechanism, so you might need to check that area too. That if you don't have 12 volts at the lamp sockets while depressing the brake pedal. Bad lamps or sockets are the first things to check tho. This wiring diagrams should help you trace the brake signal, from the stop switch all the way to the trunk. Look for 12 volts at the brake switch and follow the wire colors shown on the diagram. http://www.gvtc.com/~rlaa/

Emergency flashers overrule all other circuits.
If flashers work, then proceed with Orench's suggestion of turn signal switch, maybe giggle the handle.

If brake lights don't work, power to brake switch? Through switch? Power to fuse panel?

Re: Brake lights not working?

On the 67 and 68 models, the rear lights ground through the metal housings. It is very common for a bad ground there to make the brake lights stop working. Try removing the light sockets and clean up the area where they contact the housing with some 180 sandpaper or steel wool. Clean up the little metal tabs on the light sockets themselves too.

If that works, you'll just need to maintain a good connection. I got tired of doing that on my 68 and swapped the sockets with parts store replacements that had a ground wire, and grounded the sockets to the trunk latch brace, like a 69.

Re: Brake lights not working?

Have you tried testing the wiring with a test light or meter. Start at the brake switch. It has a orange and white wire on the switch. See if you have power on the wires. You should have it on one side of the switch and when press the pedal and you should have it on the other wire. Then work your way to the trunk and test the wires there.

Based on the above I'm guessing that the brake light works with the turn signal. I think the T/S switch is bad. If the turn signals work that pretty much rules our the bulbs and sockets.

The brake lights go thru the turn signal switch on the white wire.

Test with the turn signal working to one side, then have someone depress the brake pedal and see if the signal keeps blinking. Then same test to the other side. If the blinking stops while the brake pedal is depressed, most probably your turn signal switch is defective.

Recheck at the switch, it wouldn't be the first time a new switch was bad.

Inside the steering housing. You need to pull the steering wheel to get at it.
