Hello again.Air in your brake system would not be your problem.When a brake caliper hangs up,it means that the piston is not releasing all the way,causing the brake to be applyed all the time on the affected wheel.Does your car pull to one side when you apply heavy brake?Also it could be your flexable rubber hose going from the body to the brake caliper that could be bad.They tend to rot out on the inside allowing brake fluid to go to the caliper,but not return to the master cylinder.If the caliper turns out to be bad,just replace it.Let me know what happens.Have a good day!!
