When we drive the truck, when you press the brakes they often go all the way to the floor. Driving while on city streets as well as on the freeways. You have to pump them in order just to stop before hitting anyone. After driving 30 miles, we have to refill the master cylinder with brake fluid. We have taken it to the mechanic three times for them to find no leak. A friend looked at it and found that the master cylinder is leaking into the brake booster. We do not feel safe driving this vehicle in this condition. I have an article from fox news stating that our year 2004 Toyota Tundra is included, but when I called the dealer as well as entered it into your system, they state it is not. This is a dangerous condition and I strongly feel that our vehicle should be included in the recall. We have a new driver driving and will not let her drive this truck in this condition. We would feel much safer if this could be repaired. We have be fortunate to not have had an accident, but we have had many close calls, and the leak seems to be happening more and more often.
