Land Yacht Brake Fluid Loss

[wolos]

Help!
I'm in a 2004 Airstream Landyacht (30').
Just checked in to Fort Clinch State Park in Fernandina Beach, FL. On the way to my campsite, brake pedal went to the floor and brakes failed. I can see that fluid is dripping under the engine, between the front wheels. Trying to get a mechanic lined up for a "house call" on Monday morning. I hope it's just a failed hose. Can anyone offer some insight to this issue while I wait for help to arrive?

When this happened to us last year the master cylinder had failed. On ours the leak was slow enough that I was able to refill with brake fluid and get enough pedal back to be able to drive for awhile.

What type of Tow vehicle? It could be lots of things. It is either the master cylinder seal or a brake line has busted. If it is the master cylinder fluid will be leaking from the brake booster on the left side under the hood near the top. If the leak is somewhere else then it is probably a busted line.

Perry, there is no tow vehicle. My Landyacht is a 30' motor home. I'm trying to schedule a tow truck for tomorrow morning to get my Landyacht to a service facility. I'll post again once it's fixed.

When you do get to repair facility have all brake lines (rubber and metal) checked. At 15 years old (mileage does not matter) the system is at the age of needing attention. Brake fluid absorbs water so the entire brake system should be flushed every 2 or 3 years. Flushing the system also helps prevent seal failures in the master cylinder and calipers. Brake fluid also boils at a lower temperature when fouled with moisture resulting in loss of braking when going down that long steep hill. Maintenance 101. Hope you get fixed and back on road safely.

Uraljohn, thanks for your advice. The root cause of my issue was a rotted metal tubing section of my brake line. I had the piece replaced and then had the entire brake system flushed. Now I'm good to go. Master cylinder was ok. Thanks for all of the great advice.

Glad to hear you were able to get repaired and everything checked. Safe travels to you and family.

Just curious which section rusted out?

I've had that happen on a couple cars, while driving

when you have a good opportunity I'd replace all the brake lines with new stainless steel and new drop hoses, only a matter of time before another section goes.

I'm not sure exactly where the rotted metal tubing was under my coach. The mechanic told me that it was part of the line connecting the rear brakes to the front brake line.
