Follow up to my brake light switch question

[samdjr74]

Hi All,

I'm just wondering if going with a mechanical brake light switch is a better option? I need this for the TC lock up as well so I'm going to need a 4 contact switch. After reading up on this it sounds like the pressure switches leave a lot to be desired. Has anyone mounted a mechanical switch in their 2nd series? If so got any pictures? If the pressure switch is a popular choice any one have any feed back on it?

Thanks,
Sam

anyone?

on my old rigs i have always used the existing mechanical switches. easier to diagnose when they go bad and don't need to bleed the brakes when replaced.

Thanks guys, does anyone have any pictures of these installed? I'm having a hard time visioning how this will mount in my 56.

Thanks,
Sam

Does your brake pedal mount under the dash or under the floor?

I'm running a CPP firewall mount MC with the bracket that replaces the stock dash bracket and the pedal hanging down from the bracket assembly

awesome, that makes it much easier... because its not under the truck, it doesnt have to be weatherproof.

Just go snag a brake light switch off any modern car/truck.. i like the ones GM put on everything from the 80s to early 90s.. but any of them work.
just bend a 90* bracket to hold the switch infront of the pedal arm.

when the pedal is up, it pushes the switch in. and the lights stay off.. when you push the pedal down, the switch button goes out, and the lights come on.

for cruise, you put a second switch right next to it... you may need to put a small bar or tab across the pedal arm so its wide enough to hit two switches...
Or get a 2 circuit switch.

if you get the one GM put on their cars, it pushes in a grommet with a ratchet action.. so you can easily mount it in place.

I've got a pressure switch in the line on the truck now but am going back to a mechanical switch on the 48 during the rebuild.
If you have swing pedals with a firewall mounted master cylinder it should be easy to mount a bracket for a later model 4 pin switch an a tab on the pedal arm to activate it.

Floor mounted would be a little harder but can be done.

All of the mechanical ones I've seen so far show the units mounted to a floor mount style MC so at least this is good news for me.
