This could be the rubber brake hoses. They tend to come apart on the inside and cause brakes not to release

You may be experiencing caliper issues (you mentioned replacing the front calipers). Signs of a bad disc brake caliper include: * When your disc brake caliper is worn you will often hear a squeaky or squealing sound that should not be ignored. In addition, your brake pads will often vibrate when you are trying to stop your vehicle.
* Difficulty pushing the brake pedal is a frequent sign that the disc brake caliper is out of alignment.
* Drivers may experience the vehicle pulling to one side while braking.
* Excessive heat or smoke coming from the wheel area.
