Possibly a sticking caliper. Did you clean and grease the caliper guide pins? Could be proportion valve in the brake booster is stuck also.

Well if you get a new caliper now would be a good time to flush out all the old brake fluid and put in new. Be shuts to bleed all the air out. Good luck

I believe they have a caliper rebuild kit. But I would just get a rebuilt one from rock auto.
