brake light switch issue.
#11
I remember having to adjust the push rod when I installed a new brake booster. When I was adjusting it I got to a point where the lights were always on and the I backed it off until they went out. My lights come on as soon as I touch the brakes now.

Sorry to resurrect an old thread, but I'm doing it anyway. I have power at both switch contacts with the pedal resting (not depressed) and still no lights. New master/booster, new brake light switch and new turn signal switch. Turn signals work fine as do the hazard lights, pedal travel/feel is good. One thing to note is I am missing the outer nylon spacer that goes next to the cotter pin. The reman booster I got said it had an improved bushing/spacer, so I got the impression I didn't nee the outer spacer.

Can someone help me understand how the switch works, because it doesn't seem to move at all when I depress the pedal by hand under the dash. Should I adjust the booster pushrod?

After further troubleshooting, I removed the inside spacer as nailpounder suggested, and turned out the pushrod a few turns. I can now manually depress the switch with my fingers and get the lights on, but not with the pedal. The bushing seems to be hindering pushrod travel to engage the switch. I am hesitant to simply remove the bushing and have the rod eye flop around the pedal pin. Any suggestions?

Edit: I took out the bushing and the lights work fine with light pedal pressure, so I think I'll leave it that way unless someone talks me out of it.

I'm mostly concerned about wear over time, but I don't plan on driving the car a whole lot and not in hard braking conditions, so I think it will be ok. Thanks for the tip.
