There is a tool I'm attempting to date labeled "Chevrolet Brake Tool" that has a stated purpose of "Installing and Removing Friction Pin Lock". Showing my age I presume, but I've not heard of a "friction pin lock" in brake systems. I'd appreciate any education you may afford on friction pin locks or date ranges where friction pin locks were (or were not) in use.

Here's a 1950 tool....(So they were still using them then)

(If I remember correctly, old chev brakes had opposed shoes instead of shoes with a common anchor pin. so the lead shoe has an anchor pin and a spring, and the trailing shoe has a seperate pin and a spring, perhaps that is what they refer to as the friction pin? (One shoe was called the friction shoe, as it did most of the work),,,,,

It does seem to be the same tool I'm researching, but I see no maker reference in the "shopping" section of Popular Mechanics.
A picture of the tool (and it's illustrations) I'm researching.

This is the Veteran Chevy Club site, they will be glad to give you more info then you need , LOL.
I believe it's a pivot pin that wears and sometimes seizes up.
The tool allows you to work on it with out taking all the brakes apart.

Does that bring back memories, when in high school, working on my 1950 Chev four door. Never knew about the tool, and took a pair of vise grips and two screwdrivers to muscle that spring off.
