560sl rear breaks
 

I have a 1986 560sl and all of a sudden the rear breaks are locking up.
I replaced the calipers and pads and rotors.

If I drive it a block or two after applying the breaks a few times they lock up or drag slightly.

What am I missing?

Is the break fluid bad?

Well i purged all the old break fluid out of the system and everything seems to be working great.

The only question is what is the proper break bleeding sequence for the 1986 560sl.
