Being the old mechanic I have a half dozen brake spring tools in my box. I notice one of the young guys doing drum brakes and just wait. After the cussing goes on for a few I walk over with the tools in my pocket, watch. then hand them the right one, for the stubborn spring they're trying unsuccessfully to hook up. Sometimes even show them how its easier and faster with the right tool. Fewer bloody knuckles, less looking around on the floor. Amazing number of small cars and trucks still use drum brakes on the rear. Some, one simply cannot do without the right tools. Some guys would rather just cuss dumb stupid drum brakes than do it right.
