Thats because the Break light was Broken
Howard, give me a break, I was on coffee break.
With my ADD, I don’t get along with electrical. Lol
Or was it a coffee "Brake"???
Is the standard factory brake light switch adjustable for sensitivity?
I was checking my CJ5 brake lights to see how soon they actuate with pedal movement/pressure. It takes a LOT to activate the brake lights, or more than I’m used to like with a modern car, so my customary flashing the brake lights method [tap-tap-tap and then braking steadily coming to a stop] might take more effort.
Might have to get that NAPA lever brake switch mentioned in post #17. . .
It's not adjustable.
You may need a new switch or it may be gummed up with crap.
There are low pressure hydraulic switches. Check '''ronfrancis.com" . Part SW32. It costs about $30. I use one and it really IS low pressure.
Agree, they lights should be on as son as you feel a bit of resistance on the pedal.
Mine had the same issue. They only came on during a very hard stop. Replaced the pressure switch and now they come on with a very light press, not even enough to start slowing down.
Well I'm in the same boat. I tested the two writes by jumping them and lights go on. Since the switch was old, I had a replacement from Walcks in the just in case box. But still no lights. Just to make sure it's not a connection, I shorted the outside of the brass connectors that are actually part of the switch and I get lights. So it has to be the switch. Maybe there's an air bubble as I am in the process of bleeding after disc conversion and all new lines. Is there a way to dry test these?
I changed mine recently with help of the forum, works perfectly. It is located near the engine, up, no problem. There is an other one near the brake pedal, but disconnected.
Air will not activate the switch like fluid will. Bleed the system and try again.
Took a quick halftime break and sure enough give it enough pressure and they come on. For the past 3 years, I've assumed there was an issue somewhere. In another thread I had posted about the PO having an extra wire run from the headlight junction circuit all the way to the back and could not figure out what it was for. Now I'm wondering if it was to force brake lights on manually by pulling the light switch.
In any event, I need to find one of those low pressure switches. Anyone know who makes one that has female connectors?
Mine are original? When I did my frame off repair and repaint,
I remember thinking I had never seen a switch like this?
Didn't know I could buy them,so when I replaced all the lines I just cleaned
them up as best I could,brake cleaner straw in hole,until it ran clean.
They work great, light pressure on pedal, and their on.
To the OP.
Have u flushed your system really well, all dirt out?
My wire connector is a flat female spade, like u plug on a atc fuse, had to squeeze it a tad with pliers.
Also used some dielectric grease on connection. Been like that 3-4 years now.
I was thinking about trying to clean the original out and use some air pressure to see it it lights up as I'm having hell getting the new one to stop leaking.
