Like many important automotive innovations, power steering and power brakes were not invented in the era that saw their widespread use. These features were more common on high-end and luxury vehicles at the beginning of this decade. However, by the end of the 1950s, many mid-range cars were also fitted with this groundbreaking technology.
The 1950s
It started in 1951 with Chrysler’s Hydraguide hydraulic power steering system.
This system used hydraulic fluid pressurized by a belt-driven pump to push and control steering racks. Hydraguide required regular checks and maintenance to function as designed. The technology set a new standard for luxury in the early part of the decade, and despite being an expensive option at the time, it quickly became popular thanks to the greater ease of driving it offered.
The same popularity and acceptance followed the introduction of power brakes in the early ’50s. Chrysler was an early adopter of hydraulic power disc brakes, which became more commonplace than their traditional (and less effective) drum brake counterparts.
Eventually, these systems were replaced by the electronically controlled versions we know today, but at the time, these innovations made vehicles more accessible and practical for millions of drivers.
