Hello fellas.. I'm. new. to. the. Montero. just bought a 2002.with 140k a week ago.. been working on getting it to. shape. .

this is my firs vehicle. without a regular brake. booster and I was wondering if that little electric noise devil it's supposed. to be working on and off non stop all the time..

plus it's normal that u can hear it loud and clear while. u are. driving inside the car??
thanks in advance
