The front brakes on my Model A has a "lower clovis set up". As the brakes are applied, the operating pin pushes down, making the clovis pins move horizontally which push the shoes to the drum. I realize the normal usual system has a operating wedge but mine has a "clovis set up". Anyone familiar with what i have in my front brakes vs the usual operating wedge ? Thank you.
