These look just like AC brakes for a model T but are larger. Any Ideas?
AC 1926-27 if they fit a 11" drum (big drum style)
They look like AC Model 6 brakes for the improved Ford (large drum).
That's what I thought but check this out could they be for a TT
Mis-match-mix of parts I think. The AC forward mounting brackets look to be the originals that the new RM brakes are copied from. They are intended to mount on the radius rod bolts, and have a round rod for the brake lever to pivot on.
The bands and arm linkages may or may not be intended for a model T. That was a common type of brake used by hundreds of cars during the '10s and '20s. They mount from a rear anchor point and should have a square post to allow the band to slide forward and back as the brake was applied (small springs are involved in the anchor posts). This action helps keep the brake band from dragging when not being used to slow the car.
Those bands could be from a TT. They look a lot like the TT Bennett set I had years ago.
I remember when Jack Sunderlin was making what he thought would be an improvement over the old original Rocky Mountain Brakes, and that is exactly what he did. He copied the large drum AC brake. I don't know why he chose rods however.
