Did you replace the bracket and abutment clips. Do your pads slide freely? Compare each side. Mine get a lot of build up of dirt/friction material.
I would remove both front calipers from the bracket individually. Have a friend apply the brakes a couple times while you hold the caliper with the pads onto the rotor. Then compare the difficulty to slide the caliper and pads off the rotor. Does the right caliper have more resistance the left? If so, you have a hydraulic problem. This will prove/disprove that the issue has anything to do with bearings, rotor, guide pins, or pads.
Yup brackets replaced, clips all new, everything's all new on the caliper.
I've already checked and the right sided has way more resistance than the left.. It has to by hydraulic issue since everything's been done including new brake flex hose
