break light switch question

[arcatchman68]

Hey guys maybe you can help me out with this. My 68 coupe brake lights only come on when the pedal is all the way down. During light or even medium breaking the lights are off but the brake lights work for sure. I am thinking that this has to do with the mechanism that engages the switch and the plunger is too short? Looking into a replacement switch from mac's antique auto. I'm hoping a modern switch will be the trick! any thoughts or suggestions? thanks!

Hi,
If the brake lights worked fine throughout the pedal travel before, then I would not say the pushrod. Without seeing it first hand it sounds like a bad brake light switch,they do go bad and will give you the symptoms you are having. Not to throw parts at the car but I'm 99.9 percent certain that will fix it.

I have disk brakes and the lights have never really worked well through the light cycle at all! just when i mash my foot on the pedal do they come on

In light of that info, you may have a problem with pedal travel/pushrod. How does the contact part of the pushrod look ? To get a good look you have to remove the brake light switch, To me if you're doing that you may as well throw a new one in they are a cheap ,less than $10 part.You will most likely find the original switch when you take it out. I'm still leaning towards a bad switch.

A bad stop light switch is what it sounds like to me too.

Like mike said, it's the brake light switch.

Dear this isn't the big issue. Its might be due to brake switch, that loose its grip and need to replace. Also with the passage of time this type of parts need to replace. Not a matter of worthy, just check your vehicle to service man in regular intervals for maintenance.
