Q: Why are my Front right and back left brake calipers are sticking? 2007 Hyundai Tucson

Hi there - you may have [brake calipers that are sticking}(https://www.yourmechanic.com/article/top-10-brake-system-issues-every-car-owner-needs-to-know), and causing the brakes to drag. Or, you may have a residual brake pressure valve that is not releasing brake line pressure like it should. Modern brake system engage brakes diagonally - one brake circuit engages right front and left rear, the other circuit engages left front and right rear. If your brakes are dragging on a diagonal pair, the problem is more likely the residual pressure valve. I recommend a brake inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
