Hi and thanks for using 2CarPros. Com.
Since the calipers are new, there is a good chance that the rubber brake hose going to the caliper is bad. Over time, they deteriorate internally The result is that when you apply pressure, the force is strong enough to force brake fluid to the caliper. However, when you release, fluid cannot flow back to the master cylinder. The result is a sticking brake.
Here is what you can do to check: It will require a helper. Safely lift the passenger side front wheel from the ground and support the vehicle with a jack stand. Next. Try to turn the wheel. If it turns, have the helper apply the brakes until you can no longer turn the tire. Next, have the helper release the brake pedal. You should be able to turn the wheel. If you cannot, locate the bleeder on the brake caliper. Open it to allow pressure to be released. If you can then turn the wheel, replace the rubber brake hose.
I have attached pictures from our site which are used to describe bleeding brakes. In your case, we just need to release the pressure at the caliper to see if that in turn releases the brakes.
If the brake still does not release when you open the bleeder, either you have a bad caliper, the brakes were not installed correctly, or a bent or frozen slid pin.
Try this and let me know what you find. Also, if you have other questions, feel free to ask.
Take care,
Joe
