Make sure that all 4 calipers are travelling in and out smoothly... You would have to remove the wheels and manually push the pistons in ( a "C" clamp is a simple way to check this..) and see if they all move in with the same effort.
Remember to protect the pistons from coming out too much if you apply the brakes with the calipers free..
For the calipers again..
If not, you might have corrosion behind the caliper piston and out of sight. One reason why we change the brake fluid on a regular basis..(usually 2 years..for the fluid..)
Let us know if you find anything..
