How do you adjust brake light switch?

I replaced my master cylinder today with one from Autozone due to leaking cap/top. Now my brake light won't go off. All I can figure is that that the shaft on the new was a little longer than the old one. Anyhow, does anyone know of an easy way to adjust the switch? I can hardly get my hand near the switch much less adjust it.

Thanks, Howard

The shaft was shorter, anyway, it helps to be a contortionist. I used a open end wrench, once the nut closest to the firewall is loose, I used one finger to turn them. Its a royal PITA.

You may have pushed the switch up in the bracket when you were doing the install. The switch is threaded pr ribbed on the out side and it just pushes into a bracket and the "threads" hold it in place. To adjust have the brake pedal in the relaxed (ie foot off) position and reach in and push the switch in until it bottoms out. There is no real push back pressure on the switch so it doesn't need to be hard/solidly secured. again chances are when you were playing the the master cylinder rod you probably just pushed the pedal up far enough to move the switch, no biggy. At leadt this is how my 84 is so I feel sure your 83 is that way as well, and yes it is a PITA to reach.

Good luck.

The one I just replaced uses 2 nuts. And it may be possible to bend the tab on the brake pedal a little.

Interesting, what year? Just learning Jeeps, and yes with the type that secures with nut you can adjust (read bend) the bracket for proper adjustment.

1980 CJ5 , the bracket can only be bent, approximately 0.125" to keep proper contact. IIRC the hanging pedal set I took from a 1995 YJ, was the same, 2 nuts, and my 1983 CJ 7 is the same as the 1980.
Good luck HMS.

That's strange, I moved mine last weekend when I was fixing the ignition cylinder rack & pinion (?gears behind the key). I reset it in the fashion mentioned above, it definitely had no retaining nuts. I am just beginning to learn Jeeps, so I ask questions. Mine is an 84 powersteering, non-tilt column, manual brakes with a T4 if that matters.

Just checked my 1984, it has the "slide" type you describe. So Im probaley mistaken on the 95YJ.

My 84 switch worked this way on my 76 brake pedal also. I updated the 76 harness to an 84 harness.
