Replace Calipers?

[bware113]

My Drivers side rear caliper is locking up and has been for a while. Also I did a full brake job on the car about 3 weeks and the front calipers are acting up. Im geeting a squeal up front which has become almost a grind. There is a thin line or a streak on the rotor used to be wat appeared to be gunk is now wearing out the rotor slightly. The rear caliper is getting dragging badly enuff to the point I can smell the rotor and feel the heat off of it.

Do you guys think I should just fix the reaccurring problems or do a 3zx brake swap all around to save on a headache and maybe a little time?

from your description you have a failed caliper.. so it appears.. i want you to disconnect the hydrallic line from the caliper and connect a pressure gauge in its place.. using a mirror step on the brake and see how much pressure is coming from that line.. if you have adequate deflection then its the caliper.. ok. but if not under the car thee is a tee that difertes the fluid from the mastercylindre to the two wheels. the line going to the wheel could have collapsed
