ok so i was at a light tonight and my brake petal went flat, my brakes still work but very poorly, I checked my brake fluid and it is low (below the low line) to be honest I have never checked the brake fluid since I bought the car 2 years ago, its a '99 grand cherokee, also the brake fluid it very dark brown, is it possible that my brake fluid could have just gotten low over time and caused my brakes to die suddenly at the stop light or did something break and caused the fluid to drop drastically? its 1am so i can't see if anything is leaking i'll check tomorrow morning though
