never had this issue before with a car before, Im finish up the wiring in my 67 gto, but having a issue!
I have taillights & both rear turn signals.... but NO stop/brake lights!!! checked the brake swith, it is good, but went ahead & removed it, installed a jumper wire ( getting full 12 volts from orange wire., checked fuses... all good, checked all wire connections good.

I also noted that when I turn on the 4 way flashers, only the front parking lights flash , no rear lights flashing, while I have the flasher on & press the brake pedal, the flasher in the dash stop flashing & stay on until i release the pedal.
I have rear turn siginals, & running lights, but no brakelights......in all the cars I've had over the years this is a first for me, it alway was a fuse or a bad brake switch,when i had no brake lights, so I have no idea what the problem is, electrial is not my strong suit. Im just guess but could is be the turn siginal harness in the steering column???
thanks for any help,

The reason the flashers stop when you press on the brake pedel is that is the way there are made. Up until about the late 70's early 80's most all cars when you press on the brake pedel stop the flashers from flashing. Later on most of the car companys fixed that by rewireing the flasher circit to let the flashers flash while the brakes are applied. Right now it sounds like you have a ground problem with the first complaint.

With rear turn signals working and 12v measured at output of brake light switch when pedal pressed the only things left is the circuit between the brake light switch and the turn signal switch or the turn signal switch itself.

In regard to your brake light issue in 2013, what did you find out? I am having exactly the same issue now and I am suspecting the turn signal switch after checking all circuits, brake switch, etc.

I would try plugging in a new or known good turnsignal switch and retest.
