Didn't have anyone cut me off nor did we crash but I sure know how you all felt!!
We were headed east over the North Cascades highway (Washington State) in a 1977 22' "C" class motorhome pulling a 22' ski boat with surge brakes. Had my wife, 3 daughters, 2 nephews and my favorite dog with me. They were all out back playing games, listening to music and had no clue what was going on. We were on the east side of the pass which at times is very steep and winding back and forth. I had been pumping the brakes from time to time because I didn't really need to use the gas and all of a sudden my brake pedal goes to the floor! I pump it a few times but nothing!! We're building up speed going faster and faster then I notice off to my right is a 500' embankment filled with 4' stumps and no guardrail!!! I don't say anything to the family because I don't need 6 other people freaking out right now. So, I keep it on the road best I can and use the e-brake and transmission to help slow us down. It seemed like an hour but really was only minutes and we finally came to a stop. Thought everything was over but discovered another problem ... we're on fire!! Had flames shooting out of both front wheel wells. I guess when the brake booster went it leaked fluid down the lines to the already smoking hot brake disks and caught fire. Luckily I had working fire extinguishers on board and was able to put it out without anyone getting hurt nor a lot of damage to the rig.
If we had gone over that embankment, the motorhome would have come apart much like the fence that Blitz destroyed!! I spent the rest of that long weekend thinking of what could have happened and how lucky I am.
