Brake Fluid Master cylinder

I have a 2003 Hurricane Thor and I have hydraulic brakes. When parking the other day, the brakes went to the floor. So, that leads me to believe that there is a leak. Problem, I have never had this problem on any vehicle that I have owned. I can not find the Master Cylinder. I have went through all the books and it does not tell me. I need to find this to see if I need to add fluid or have a broken hose or something else.
Would anyone have a thought where to look, so I can get it fixed. Right now, I am parked on a Naval Base and I will be there for at least a month, but I don't want to wait that long to find the problem. It is 35 ft long Class A Motor home. Thanks for any info you can give me.

First question will be is it a ford or workhorse chassis?

That said, the master cylinder will be under the front hood, drivers side, high up.
If your pedal is going to the floor, you have a leak. You'll need to find it, fix it, fill the system with fluid, and bleed any air out of the system.

That is a dual braking system. So if the pedal went to the floor you should have a brake warning light on the dash. The most common failure is the master brake cylinder and it is normally caused by water contaminated brake fluid corrosion. What ever the problem is you should have the brake system flushed and all new fluid installed.

I look under the hood everywhere and found every thing but the master cylinder. I will take another look and see if it is there. I may have to call a mechanic to come and see the problem. Thanks guys

If you have a workhorse chassis, Look inside the drivers side front wheel. It will be about the same level as the top of the wheel. There is a cutout in the splash guard for access.
