Bleeding Brakes 90 b2200

Is there any trick to bleeding the brakes on my b2200. I have a great pedal on the second pum and have beld the brakes a lot. It has the anti-lock brakes and only one rear bleeder screw on the left side. It also has one on the antilock brake assembly. It htere a trick or do I just need to bleed another gallon of brake fluid thru it. Any response would be greatly appreciated

I have a 90 b2200 and I just bled my brakes and it was really easy. Just start with the farthest and work to closest. So back, then front right, then front left.
