Had that happen before. Pulleys will get small grooves in the side from constant trolling.
Visually inspect them.....if you notice little grooves, get some "extra fine" sandpaper and smooth them out.
Both wire and braid will put grooves in the pulleys. When you wind in the riggers and the line is on a bit of an angle sometimes this will cause a groove over time.
If you used wire before....the braid will catch in the groove the wire made. But braid will put a groove in them too.
