hey i was driving today in the rain and my dash brake light started flashing and beeping, so i pulled over, turned it off and back on everything seemed fine so i continued cautiously, then when i pushed on the brakes and it sounded like something something was hitting when i would push on the brake, so i pulled over checked the fluid it was fine, took a quick look at the rotors and nothing seemed out of place what could it have been, i have a code checker i used it and nothing came up

 

welcome to abs break systems
that is normal in slippery conditons

 

no it just says brake in red and it flashes and beeps

 

Could it be the brake wear sensor?
