1952-59 Ford 55 Ford brake lights not working

Hey guys. The brake lights on my 55 Ford Country Sedan recently stopped working. (I had to find out the hard way with a guy pulling up next to me and bringing it to my attention.) The taillights are getting power. I cleaned the connections on the two plugs connected to the switch attached to the master cylinder. Still nothing. I traced wiring under the carpeting as far as I could. It seems fine. The wiring in the tailgate seems okay as well. Thoughts?

 

Are the light fixtures grounded to the body? I would remove them and ensure you’re getting a good ground. Also consider running a dedicated ground wire.

 

I think it's the brake light switch. Ordering a new one on Monday. Thanks guys.

 

Brake light switch on the master cylinder……. Get one from a Harley Davidson dealership. Best ones out there !

 

I found a good one on eBay, trips at 25 psi. I have a spare in the glove box.

 

If you still have the original master cylinder those are prone to failing, some guys convert those to something like this, it is a GM switch with a homemade bracket has been done often.

 

On my 54, I converted to n electric switch. This is the best thing.. If adjusted right, instant brake light when you touch the pedal to warn the other drivers.
