Here's a good one! I was running a route in another town years ago. The normal 800 was red tagged for bad brakes. They gave me another 800 that ran a city route and had probably never gone over 40 mph in years. Running down the highway at about 55-60, the thing suddenly starts bogging down as if I had turned the key off. I start to hear this hissing noise and I looked down to the shifter (where the noise seemed to come from) just in time to see smoke and a wad of grease shoot up to the ceiling of the cab. I was able to roll into a lot that was fortunately right ahead of me.
I called in and the mechanic said he had nothing to bring out to me. I told him that this one wasn't going anywhere. He covered the phone and I could still hear him yelling in the background. He then gets back on the phone and says he will be there as soon as he can. When he showed up, he was driving the car original to the area. We switched the load (always a whole lotta fun) and his last words to me were......"Be careful......this one doesn't have any brakes..."
He was right........you had to pump them every time you wanted to stop. Obviously, I lived through it but my nerves were pretty much shot by the end of that day.
Just one of many times I've dealt with broken equipment over the course of my delivery years. Some worse than others and this one ranked right up there.
