front driver caliper and rear right passenger caliper locking up?

Hello, lately it has been giving me braking issues. My front driver's side wheels lock up. I replaced the hose and caliper with new ones hoping that would fix the issue. When I put everything back together, and bled the caliper it locked up again. I took it upon myself to check the other tires making sure they're all good. To my amazement, the rear right passenger side wheel is also locking up along with the newly installed driver side caliper and hose. I bled the rear caliper, and it released the pressure making all the wheels spin, however when I applied brakes, the rear and front would lock up again. This is frustrating so any type of help or wisdom would be greatly appreciated at this point.
