speed sensors?

If I unplug the sensor for the Master Cylinder the Brake warning light turns off but once i plug it back in the warning lights up again. The switch i assume stays On, anybody here knows if the switch is normally open or closed maybe I can use a reader to reset it and see if it comes back on?

any error codes? /check engine lights?

No check engine light, when the read switch for the Master Cylinder is connected you get a Brake Warning and VSA warning. The Read switch reads the level of the brake fluid in the reservoir. The brake fluid level has been solid, it hasn't lost any, no abnormality on the brake system except the read switch. I unplugged the read switch and instead have been monitoring the level, so far no drop of level.

front and rear brakes new. maybe they damaged the ABS sensor.
You have to get a code reader that reads B-CAN codes. From there you'll get a "DTC" code for the reason your brake and VSA light is on.

It's either going to be a speed sensor or Wheel Bearing.

I have a Reader, its the sensor for master cylinder, Acura dealership had already confirm it too.
