I am trying to improve the brakes on a Libelle 201B. I replaced the shoes and de-glazed the drum recently but not much help.
I trued the drum on a mandrel in a 10" Clausing lathe. I mounted the backing plate and shoes on another mandrel, intending to true the shoes, but got readings that told me the shoes would have to be expanded.
I had no good way to do that without getting excessive clearance. So I just deglazed them.



After installation, I had to max-out the one adjuster in order to get the proper tension on the handbrake.
I noticed a threaded hole in the brake handle, centered on the cable. Looks like a setscrew belongs there for adjusting cable length.

So--here's my question-----What style of setscrew point belongs there? Flat tip, or dog point (extended tip). I presume a cup point would damage the cable.

Thanks in advance for any factual knowledge.

Mine (SN 470) has a hex-head bolt with a slot for a screwdriver. The end of the shank is flat.
