I did a brake job last fall. Replaced all rotors and pads. When I did the rear brakes, I had some problems:

- The single retainer pins were difficult to drive out.
- Both calipers were really rusty.
- On one side, the caliper was so rusty that the replacement pads would not fit into the caliper. I had to reuse the existing pads on that side. It wasn't very worn, about half life, so I reused it and crossed my fingers

At first, the new brakes were OK, but not great. I felt a slight warp at first. Now, after about 10,000 miles, they're horrible. I have a bad pulsation on the pedal, squeal when I come to a stop. Sometimes, first thing in the morning, they grind a little.

I need to fix something, but what? I was considering replacing the rear calipers. Anyone have advise on where to start? Thanks for any advise!
