Clutch Motor without Brake

[friquant]

Is the brake optional on a clutch motor?

I've been working on my clutch motor skills. In part to be better qualified to write this blog article: https://leatherworker.net/forum/blogs/entry/516-option-c-clutch-motor/ , and in part to satisfy curiosity. I've greased the pivot points and the main slide sleeve to improve the control and feel. I've slowed it down. I've backed off the slack adjuster in the brake far enough that I can consistently release the brake pressure when I want to use the hand wheel. But I keep asking myself, "Do I really need this brake?"

The universal motor with triac speed control (aka "analog servo" aka "brushed servo") that I had for a few weeks also came with a brake shoe that activated whenever I was not on the gas. With that motor, I liked it better after I removed the brake shoe entirely. 

So I've been wondering, what is a straightforward way to remove the braking effect from a clutch motor, and are there any known downsides to doing so?

The brake in a clutch motor is to stop the sewing machine when the "go" pedal is released even through the motor continues to run.  In a servo motor the motor stops rotating when the "go" pedal is released so a brake in reality isn't necessary when sewing at slow speeds. At high speed sewing it would be possible to get some run on.
