1. Brake Booster Issue: The brake booster is responsible for assisting you in applying pressure to the brake pedal. If the brake booster fails or malfunctions, it can cause the brakes to drag or stick. Check the brake booster to see if it is working properly.
2. Master Cylinder Failure: The master cylinder is responsible for distributing brake fluid to the calipers and wheel cylinders. If the master cylinder fails or malfunctions, it can cause the brakes to drag or stick. Check the master cylinder for leaks or other signs of failure.
3. Caliper Sticking: Even though you replaced the calipers, it is possible that one or both of the new calipers could be sticking. Make sure that the caliper pistons move freely and that there is no corrosion or damage on the caliper slides or pins.
4. Faulty Brake Hoses: If the brake hoses are old, cracked, or damaged, they can expand and cause the brakes to drag. Check the brake hoses for leaks or other signs of damage.
5. Improper Installation of Brake Components: If any of the brake components were not installed correctly, this could also cause the brakes to drag. Make sure that all the components were installed according to the manufacturer's specifications.
If you are unable to find the cause of the front brakes dragging, it is important to consult with a qualified mechanic for further diagnosis and repair.
