Default 1970 Brake Calibers

I finally got back to doing some more work on my baby. I ran across the correct bleeding sequence and wanted to get all the air out of the lines. Each tire was removed and I proceeded to bleed each line. Starting with the left rear inner then outer. Moved to the right rear inner and outer and noticed something odd. The caliber on the left had 2 (inner/ outer top) bleeders where the right rear had 3(inner/outer top and one outer on the bottom. Might I have the wrong caliber here. I believe there should only be 2 on the rear calibers. (note:The left rear doesn't even have a way of putting in a 3rd bleeder.) The fronts each have just one.

Should this be a concern?

Your input would be appriciated.

Each rear caliper has two bleeders - inner and outer. None has three, but the lower port on the outer caliper half will be plugged with what looks like a bolt.

Front calipers only have one bleeder.

you also start with the furthest caliper from the master which is the right rear

unless when bubba rebuilt your caliper he used a bleeder instead of a plug, but as mentioned you don`t bleed the bottom one

thanks for all the replies.

No one has touched the car but myself since I bought it last year. That 3rd bleeder is definately odd. Just hope it is just acting as a plug and is not interfering with the function of the caliber itself. I also noticed that the proportioning valve doesn't match the valve specific to my year. I ordered an OEM valve yesterday. This could also be contributing to some of the brake issue I am having.

Once again... thanks for the input.
