Replacing my Brakes Options

[purple]

This weekend was step one of two of replacing the brakes on my '76. The previous owner upon selling to me told me that he had rebuilt the front calipers and the brake fluid looked very nice and fresh in the master cylinder. Looks like a nice fresh tank of ATE super blue..... I will find out later that what's in that tank doesnt look like what's in the brake lines....

I started this project because when turning the wheels in the rear to set timing, I can hear the left rear brake dragging, and loudly. I feared it was a bearing, but it wasnt. The brake was dragging. I lift the car and put it on 4 jackstands, the evil kind (IMG:style_emoticons/default/sad.gif) I need some proper pin-thru stands. I have all 4 tires under the car in case the car decides it wants to smoosh me.

I'm using 4 new rebuilt calipers from Eric Shea. With these calipers are 4 new rotors, new front bearings, new seals, 4 new softlines, all new pads. A total of $1038 in parts from Eric.

From the pic...the parts are gorgeous!

Some progress and some questions:

I put the front brake lines back on and banged the new races into the new rotors, no problems there. I also put the rear hats on and was getting ready to mount the calipers when I noticed something...

My rear calipers have no gears! At least that's what I think is going on. When you take the inner adjuster covers off, there are supposed to be little gears that drop out, right? nothing of the sort came out, and nothing that looks adjustable is down that hole. The old calipers look just like the new calipers, meaning the new calipers dont have gears, and niether do the old ones!

Can you guys post pics of what these 'gears' look like please?

Thanks!
