56 merc stop light switch

I'm currently rewiring my 56 merc monterey with an EZ wire kit.There is no stop light switch at the pedal.When I looked it up the switch looks exactly like a part that was on the original master cylinder( also installing 4 wheel power disk brakes).The new brake valve has a peice with a single wire,and I was told this wire is for a warning light,not stop light.So I'm left with the dilema of how to get my brake lights to work.The new master cylinder has 4 ports on it,do I hook up the two bake lines to the valve,install the original stop light switch in one of the ports snd plug the last port.Or do I buy a button type switch and install it at the brake pedal?Or am I completely wrong in both trains of thought?

Buy a button type brake light switch for a Chevy pick up and set it up to work off of your brake pedal arm.

The one that was on it was probably was engaged when you hit the brakes to put pressure on the sw to close the circuit. You can put a pressure sw in the brake line, or you can get a lever type sw. that is controlled by the brake pedal if you have hanging pedals you will have to put it inside, floor pedals you can put it outside. Either way it rides on the brake petal arm, when you hit the bakes the arm on the sw will move and give you brake lights. I know chev use to use that type and you can still buy aftermarket new ones.

56 merc stop light switch

Thanx for the help guys!One more brake question. Since there are two lines coming from the master cylinder to the valve,and there are 4 ports coming out of the master cylinder, do I get a pair of brass plugs,and plug the ports,or is there something I'm missing?The 4 wheel power disc kit was bought from Direct Fit Brakes( no longer in business ),and the instructions are a mess!!!

The universal master cylinders often come with 4 ports. 2 on each side ... so you can run the brake lines on whichever side works best for your application. So just plug the pair you are not going to use.

I prefer a brake light switch like this.



12 volts and installed on the early 60's Chevrolet and GMC pickups ( among many others )
