I did the brakes on my Kestrel one time, long long ago... Went for a test drive, after a few k's the rear wheels started feeling wobbly, stopped, got out, and there it was, one wheel nut. The other four were lying within 10m of the buggy, they must've literally all fallen out at the same time.
I read a story once about a dude observing a taxi in rush hour traffic in JHB. So Mr Taxi was weaving and performing and gesticulating and generally gaan-ing-aan, but not getting any further than anyone else. Which is normal in rush hour traffic. And he's lane changing and pushing in and hanging out the side window, you know it already.
So the author reports Mr Taxi gleefully blowing his horn and flipping the law abiding folks a bird, looking at them out the side window, grinning triumphantly as he overtook them on the inside driving along a long row of unoccupied parking spaces. Unforunately, and unseen by him (because of his gaan-ing-aan) the row of vacant parking spaces came to an abrupt end. This end presented itself as a set of obstinate sandstone pavement blocks, put there by stone masons at the turn of last century, when they still took pride in their workmanship and did these things properly, and rainfall was expected to be much higher than these days.
Imagine the author's delight as he saw Mr Taxi's smile evaporate, anywhere from 28 to 36 bumps appear in the Hi-Ace's roof and the rear wheels running over the now detached front wheels. The inconsiderate sandstone pavement blocks remained unmoved.
