Yep wheel bearings. Doesn't take much slop in a hub to allow the rotor to wobble and cause a caliper to back off and give an extra .010 between the brake pads and the rotor. That .010 could give you brake delay, a slight pull, and funky brake pedal feel caused by that one front wheel.

Picture it this way: both brakes get the same amount of brake fluid at the same time when you step on the brake pedal. Once the pads are seated against the rotors, the pedal movement builds pressure until it all stops. If one of the brakes has more clearance between the brake pad and the rotor, the brake with less pad clearance applies the brakes first, but the other brake with more clearance lingers before applying the same pressure (if it applies the same pressure at all). The pedal feels funky because one brake functions correctly and the other doesn't. The brakes pull because one brake functions and the other doesn't. The more the difference in clearance between the brake pad and the rotor on the two sides becomes, the worse the brake problem becomes. Gene
