Speaking of engineering quirks regarding cars. My first "real" car was a 1968 Triumph GT6 that had wire wheels, like a lot of the old British Leyland cars of that era did. Unlike steel or alloy rims which are bolted to the brake drum or axle with a number of studs that transfer the torque, these wire wheels are mounted on a short splined hub about 2 1/2 inches in diameter, which in turn is bolted to the brake drum or axle. This hub has about 50 or 60 shallow grooves that mate with grooves inside the wire wheel, on which the wheel is held in place with a little spinner cap.
Ok, so at the end of the summer a year after I bought this car, a buddy and I set out from Knoxville for a 3-week trip to Montana. Leaving late on a Sunday we decided to drive through the night. Got onto a small back road in Indiana by mistake and almost hit a cow crossing the road, just about dawn on Monday. Braked so hard, one of the front wheels' splined joint gave way and it stripped out the splines and with the car going forward that one wheel unscrewed it's spinner cap and the wheel nearly came off. We soon figured out we were screwed if that wheel wanted to come off every time we used the brakes. At about that time along comes a farmer and offered to help. Rummaging through some spare parts in his truck, we found a machine bolt with the same size and pitch as the threaded tubing connection between the brake master cylinder and the wheel, so we managed to plug the line to that one front brake, and we were back on the road!
We actually drove all the way out to Glacier Park and back, on one front brake.
