I need help with trailer

{"text":"Hi guys.\nI took a trailer from yard and trying to slide the tandem but the wheels are spinning. It’s second time in this year 🤬. \nI saw on the YouTube: remove blue air hose and connect red one to blue glad hand, that will apply air to trailer brakes. Release trailer and tractor brakes and than slide the tandem.\nI did it but still not working, the wheels are spinning.\nI can slide the tandem to rear by backing to curb but I don’t know how to push to front.\nAny ideas???
