Questions: The brake switch for my 47CJ 2A is attached to the floor and visible when the cover plate is removed. It doesn't attach to the master cylinder and appears to operate off the side of the brake pedal. Is this a modification or was another type available? I had the master cylinder replaced and it didn't have the screw in open for the switch.
Thanks,
Ken

Questions: I just purchased a new master cylinder from Kaiser Willy for a 1958 Willies Jeep. But the Brake Light Switch I have does not fit (switch fitting is way smaller than whats required for the master cylinder. Does the brake light switch listed above (BRAKE LIGHT SWITCH FITS 46-66 JEEP & WILLYS) mate directly to the master cylinder, or is an adapter required? Thanks. TJJ

This switch is just like original so you had an unoriginal one in there if its any different and you had one of the vehicles listed above. Good news is that is a common NAPA item for the wiring connectors.

Questions: I've replaced the master cylinder and the brake lights do not function. I'm guessing I installed this switch incorrectly (on the new cylinder without any fluid). What is the correct proceedure?
Question By: Anonymous on Jul 17 2013 12:00 AM
It is a pressure switch so it will need fluid and your brakes bled to work properly.
