on the rear caliper, fluid comes out of the outside bleeder free of air, but out of the inside bleeder full of air that I cannot get rid of.

help please!
 
Take the caliper off and bleed it. Leave the brake line connected, and hold the calper so the bleeder you're using is at the highest point. You may need to do some gentle tapping to help air bubbles move along.

Of course, you'll need to put something in between the pads about the same thickness as a brake disk. Worn-out brake pads are usually handy and work well for this.

Thank you. Can I leave the diaphram out while bleeding?
 
Did you tear this caliper apart?

It may be full of gelled brake fluid
 
Remove the bleeder nipple and fill it with brake fluid through the hole using a syringe or something similar.

I am going to disassemble it. Probably never been apart since 1979, and I overheated the brakes last time I rode it. Brake pedal slid to the right on the post and then could not retract fully when under the footpeg bracket.

Happend leaned over on a right hand turn. I went off the road to the left but kept the bike upright.
 
took caliper apart and found gunk in hole leading to inside piston. Gunk blew out with air compressor. Rebuilt rear caliper with all new rubber parts.

Then found not a leak but a loss of pressure in rear master cylinder. Could hear a gurgle / slurp when pressing pedal. So rebuilt rear master. Bled all brakes.

Today took bike out and rear brake works better than ever.

Thanks to everyone who responded.
