How much brake fluid do you put in 1999 dodge caravan?

tell u fill the reservoir ...you don't need to add brake fluid unless u have a leak...if your brake fluid is low but not full that means you could have worn pads and there is no need to add brake fluid....if u have bad pads u will hear a scraping noise...if the brake pedal is spongy like soft you could have air in the lines and needs to be bled...there could b more problems but that's the basics
