Help!! ABS light on!!

[slingblade]

This morning it was a little cooler here and when i started the hundy, an awful squealing, pulsing sound came from the engine bay, it sounds really close to the dash. The sound persisted until the ABS light came on and the Brake light came on, then the noise stopped after a few more minutes, and the lights reset... anybody heard of anything like this? It definitely seems like a brake system problem. any thoughts?

Check your MC and fluids.

the master cylinder looks fine, i dont know how else to check it. fluid level is at the mark, full.

Throw a reader on it and see if there's a stored code.

There must be air in the system. Bleed it properly.

Also after bleeding if the light is there then start the car and immediately press the brake padle about 15 times. Do it fast. U will hear a beep and the light should go off

thanks i will try that, i changed rear brake pads about a month ago and i possibly got some air in the system then.
