Need some help guys: Have a 95 Burb and yesterday when I was leaving out for work I noticed the brakes were soft all of a sudden. They don't go straight to the floor, but that firm wall you feel when hitting the brake initially is gone, doesn't build firm pressure until maybe the last 2-3 inches, stops but that's been drastically affected. Turns out, I lost my brake lights at the same time apparently, turn signals work (my hazards haven't since I got this) but brake lights do NOTHING when I hit em, which is a big issue obviously for driving. Truck was just fine when I was driving it maybe 3 hours prior. Any help and opinions would be greatly appreciated
