Need help about mazda protege 5

Ok so i bought calipers rotors for the second time and still my back rear tire on the driver side is still overheating so im thinking its either my brake lines or brakea hoses please help thanks

Jay , this is your second time about brake problems on this vehicle. Are you supplying the parts and someone is doing the work ? If so it is now time for a real brake shop to have this done correctly .

Got it done at the same shopni think it my brake lines guy at the shop told me of it happens again

Jay , Proofread . That sentence does not make sense.

Buy a new brake hose for that corner.

If this is beyond your abilities, admit it and take the car to a pro.

Going is optional, stopping is not
