brake lights not working correctly, swapped to new switch, still issues.

[DAGEN]

As stated my brake lights are not operating correctly. When I hit the pedal 1/4 ish they come on fine, add more pressure they go out. I figured ok, brake switch under the dash, removed replaced with new and still the same issue.... mmmkk, now im stumped. What else should I look for? I am sas'd with a hp 44 and the abs is still in the truck but no sensors obviously. I'm planning on deleting it but could this be part of my issue?

i wouldn't think so, is your switch secure to the rod??

Circuit boards in the tail lights could be on their way out. Mine did weird crap before they went. I got my new ones at O'Reilly's and haven't had a problem since

Sounds like a bad ground near the tail lights

I forgot to mention I replaced the boards on the tail lights when I did the switch. I checked the switch, it's secure, i'll look into grounds next. Any other ideas?

Mine was doing the same thing. The ground broke loose where the trailer plug in is located.

Thanks a lot Smurfcivic for the tip! those grounds were horrid. Redid them and problem solved. I also removed my ABS system today and am getting a firmer pedal now, however i'm going to remove my 1/4 line running back and replace with 3/16 from the master cylinder back to the axle. Need more pressure now that im running rear discs. Can anyone recommend a good 3/16 adj proportioning valve? Gonna need it for the rear brakes to prevent premature lockup.

No problem. Glad to help
