Hi, no pressure on your brake pedal usually means one of two things. If you have had any work done on your brakes, it is possible that there is some air in your hydraulic lines. The air simply has to be bled out. Similar to burping a baby after it finishes eating. Air in the hydraulic system causes a spongy feel in the pedal. The other common issue is a leak in the hydraulic system. The Hydraulic system is a closed system and when you step on the pedal it develops pressure. If you have a leak, the pressure escapes through there and your pedal goes to the floor. Because brakes are a safety concern, getting a technician to inspect the system and determine your problem is vital. Also because of safety, I suggest the vehicle not be driven until your brakes are working properly.
