Back in the day, when most cars had drum brakes, power brakes were not really necessary — drum brakes naturally provide some of their own power assist. The 1979 Chevrolet Impala and Caprice were a “standard of success by which other full-size cars should be judged,” according to Chevrolet.

Gregory concluded that the results were a matter of chance or explained by observations from ground surface clues.

When poured into a fish tank, it sinks to the bottom and can support the weight of very light objects floating on its surface. Pipes and makeshift bars do not have the strength to support wheels. This will also give it the most support. The positive lock-down device is used to keep a wheel held by the tire machine.
