I replaced my rear brake lines, and my rear drums on my 85ss. My master cylinder was really low on fluid after that so I filled it. I gravity bled my rear brakes and it took about 10 to 15 minutes on each side for fluid to start coming out. I went to go drive it and I’ve got a spongy brake pedal and my rear drum brakes don’t work. And another question. Should the self adjuster be hard to turn?
