Front brakes sticking

I just replace the front tire on my 1980 gw and now the brakes stick-wheel is free without brakes. Is there a left and right side rotor?

The best DIY article out there is: viewtopic.php?f=11&t=68
Be sure to measure caliper/ body clearance. Regards, Johnyy

Brakes still sticking.Plenty of clearance.Sticks even when the calipers are loose.Pistons take quite a bit to push back in-I cleaned the return port.
any ideas?

how's the gap between the caliper mounts and rotors?
21. Insert a 0.7mm feeler in between the caliper mount and the rotor at several spots on both sides of the rotor, on both the left and right sides of the motorcycle. If there is binding, loosen the axle holder nuts and adjust the fork leg in or out as required, then snug the axle holder nuts again and re-check.

Have a look at the caliper when you squeeze the brakes on. Is it moving? Then let go - is it moving again? The caliper movement should be almost indiscernable, if any. I've had a brake go spongy when one caliper slider pin seized up, causing it to bend it on application, and spring back on release.

However, chances are it's air in the lines. Try bleeding it again. You might try wrapping a bungee to hold the brakes on hard - pump them up, then hold them on with the bungee, and leave it sitting like that overnight. A lot of times that will allow air to migrate up to the master cylinder and fixes the problem.
