They are not done right! Pivot not drilled in correct location for lifting. I have another brand that works perfectly. So when I couldn't get them to pull back, I studied them side by side and concluded that although they are strong, they don't pull back because the pull back activator (the part you step on) has a low has contact. the main lever that holds the door open. The harder you pedal, the harder the main arm and rubber footrest. It should rest slightly higher and act as full support, pushing the main arm up to allow the spring to fully raise the arm.
