My brake warning light is on. I rebuilt the front calipers to fix leaks, then flushed and bled the system. I have good brake pedal and the car stops just fine. The brake warning light is still on.

I looked for the reset on the warning switch, but could not find one. Instead I pulled the switch from the master cyclinder expecting to find something to reset in there. The switch is just a plastic plunger. the connection is closed when the plunger is fully extended, open when the plunger is depressed. I pushed it, tested it, and then reinstalled. I still have a brake warning light.

Should the plunger remain depressed when I push it? Is there something wrong with my master cylinder? Is there something else I need to do on the master cylinder to reset this? How is the warning switch supposed to work?

Thanks,

Mike

The reset switch is part of the MC itself. You were looking at the brake light switch at the pedals, which has nothing to do with the reset.

You need to get under the car to reset the MC. You might be able to get to it through the drivers side wheel-well ...

I pulled the switch off the master cylinder. I read that some have a reset switch, but some don't. Mine doesn't have a reset switch on the outside.

The switch is threaded into the side of the master cylinder. It has a single brown wire. When I disconnect the wire, the warning light stops blinking.
