Which way do the caliper cylinders (rear) on an 84 el Camino to collapse them?

Bad points? Capacitor?

Did you notice the brake fluid level in the master cylinder before you tried to collapse the calipers? You should see a rise in level as you collapse them (however far they did collapse). If you're not seeing any change in the level (it should fill up) you might have a plugged valve between the caliper and the master cylinder. Loosen the brake fluid line to the caliper and try collapsing it again. If still no go, start dismantling the caliper and look for bent, broken, stuck or mal-adjusted pieces.

check or replace the bulb on the non working side

Remove the front wheel, use a flat head to take of the dust cap in the center of the rotor. There will be a big nut with a cotter pin going through it. Remove the pin and the take the nut off. After removing the caliper you will be able to remove the rotor and the bearings inside.

On the R.H side of the carb behind the automatic choke down on the rear throttle shaft there is a pin running thru the shaft with a lever that will lock it out. If the choke is not fully open or the weight behind the auto choke is not dropping the lever will not relase the secondaries to open.
