Strange happenings

Replaced front right hub on my 04 H2 but still feel a resistance in the brake pedal as well as a low grinding from that side. Checked pads they have plenty of meat. Sometime the "Active Traction" light comes on and I feel the same thing. Then at times the No ABS comes on. If it makes a difference the warning lights are yellow.
