Since the replacement, I have had three problems:
1) the travel on the brake pedal is excessive and as you slow to a stop, right at the end, it gets soft and drifts down a little farther toward the floor. Bled the brake line at each wheel, starting at the back wheels, but problem still exists (brake fluid level is fine). Was thinking about doing a complete fluid drain and replacement.
2) The ABS will kick in when you are applying the brake at low speed while turning. Asked the mechanic that had replace the rear end about the gear teeth that the ABS sensor senses, but he said they were the same (same number of teeth) as the kind that were on before (in the rear).
3) Last, the passenger rear wheel cyclically scrapes when turning right, but not left. It sounds like the pads scraping against the drum. I looked at the drum assembly. I didn't see anything that would cause it to be scraping. It didn't look like it was in great shape. I have the original drum assembly and was thinking about reinstalling them. Could have the drums turned as well. Any ideas on what the root causes are for any of these three issues?

Make sure that the adjustment of the drum brakes is equal on both sides.
Clean the drum surfaces and the shoes and check the hardware (return springs etc.) to make sure that there is equal braking.
The "completer fluid replacement is what you did when you bled the brakes. Likely the shop that did the work also did this. There might be some air still traped in the system tho...
