Break pedal spring

The brake pedal on my 1925 Model T looks like this:

At some point, a custom-made bracket was added on top of it, like this:

The lower hole in the bracket is used to connect a brake light switch. This switch has a tension spring, which —because of this setup— would actually pull the pedal down slightly.

My question is: is the spring shown in the picture only there to compensate for this effect, or did all Model Ts originally come with such a spring?

IMO, the holes, bracket, and spring were all installed by a previous owner as part of the brake light switch installation. Not stock Ford.

Thanks. I kind of figured that already. I’m not very happy with how it’s done at the moment. Do you have any recommendations for a cleaner method of installing a brake-light switch? Or perhaps a recommendation for a good switch model?

I found it pretty simple to make a sheet metal bracket that attached to a transmission cover bolt and holds a normally closed push button switch against the brake pedal. I use the spring as well.

I use the Ford style switch that clamps to the Bendix cover, it has worked well for me, although others have reported problems with it. The vendors also sell switches that mount to the frame. Model T Stoplight switch, clamps on starter bendix cover, 3158XS
