The quick chuck has been a popular adapter for brake lathes making the standard cones obsolete. But the quick chuck wasn’t large enough for the common Toyota Trucks (Tundra and Takoma). So a set of larger jaws were created. This solved a big problem. Combined with a larger plate the quick chuck was become more functional.
But there was still a hole too big. The medium duty trucks required something bigger. Here is a picture of an even larger jaw set and larger plate I sold to Action Auto in Cypress today. Notice the standard quick chuck in the background and the other chucks with larger jaws in the front.
