Heres a few more tidbits:
I pulled the wheels to get a look at the calipers. The channel in the caliper mount that the caliper and inner pad ride upon had a few indentations. I read about this in Mopar Action. Rick wrote that this area is problematic, and that a recess here could cause the pads to hang up. I took a flat file and milled down the area until it was smoothe. The pads move free now. I drove the car and noticed no improvement.
On the way home, I stood on the brakes harder than ever. It finally locked the REAR wheels. I haven't been able to get a tire to skid in months. Now with the rear skidding, it appears that I need the bias to shift towards the front. The larger piston calipers should help, right?
Oddly, the car also stops BETTER in reverse than going forward. I don't understand THAT at all. I bought 2 Raybestos 2.75 calipers and new pads. I'll get them on tomorrow and report back.
