Is there something i don't know. Like, perhaps there is no bleed nipple? The hard line goes directly into the wheel and there is no bleed nipple, nor a hole that looks to have once held one. The car is a 1971. If anyone can please shed some light on this for me i'd greatly appreciate it. Thank you.

Look on the top middle of the wheel cylinder.

At the back of the drum brake there is a hex section (longer than the front) which ends in the bleed nipple on mine. You should be able to see it from the back or underneath.

Maybe drive over some ice to see if they become more visible?

Yeah it must not be there. cause i've gotten all up in that wheel well with 20/20 vision and there's no nipple. Nor a piece extending out like where the nipple should be located. Ugh. I just replaced my brake master and i need to bleed the brakes, and clearly its not going to happen. Its not possible to only bleed the front is it?

Have you checked both sides? Maybe the side you're looking at is broken. They seal at the bottom, so the top could be broken off and it would still hold pressure.

The bleeder will break off flush with the wheel cylinder

Don't ask how I know.

I do have new wheel cylinders on my 72 z

Not if you want to get all of the air out of the system. In fact, when you bleed brakes, you should always start at the wheel farthest from the master cylinder and work to the one closest.

To clarify psdenno's statement, the drivers side (Left) rear is the farthest distance from the master due to the location of the T in the brake line back there (right side). It pretty doesn't matter which rear side you start with, I've never had trouble either way.

Keg, go ahead and bleed the others, and keep your fingers crossed. Its Christmas after all!
