Every day, countless lives are saved and accidents are prevented by car brakes. Making cars safer has been a constant source of concern for the automobile industry, and brakes have been frequently updated over the course of the history of automobiles.
In the early days of the automobile, the standard for brake safety was set by the Oldsmobile, built by Ransom E. Olds. Olds employed a braking system that used a single flexible stainless-steel band, wrapped around a drum on the rear axle. When the brake pedal was applied, the band would contract to grip the drum.
The Oldsmobile's brake became a standard for many automobile manufacturers, though it was deeply flawed. Dirt easily got into the brake, which had to be fixed every 200 to 300 miles.
European cars helped set establish the next popular type of brakes. They employed a system where discs lined with friction material would slow the wheels down. The noise made from this was silenced by lining the discs with asbestos...a material that would later be the cause of cancer for many individuals.
In 1918, engineer Malcolm Lougheed developed the next major stage of brakes by applying hydraulics to the system. His version used cylinders and tubes to apply fluid pressure against the wheels to slow them down. Lougheed would later change his name to "Lockheed," and his with brother Allan, would go on to found the famous Lockheed Aircraft Corporation.
Hydraulics did not catch on immediately, but eventually the major manufacturers incorporated them into their designs - Ford was the last to cave in, in 1939.
Other features were soon added to brakes, such as power assist, which uses vacuum boosters to help with braking. They help to increase the decrease it takes to stop a vehicle by applying a push-pull effect that combines vacuum force on one side of the brake's master cylinder and air pressure on the other side of the cylinder. Another feature that is popular in cars today is computer-assisted antilock brakes.
Antilock brakes were first developed in 1958, but took many years before they became part of mainstream automobiles. The first steps toward modern antilock brakes were taken in the late 1960s, when the Lincoln Continental Mark III was given sensors on the rear wheels that transmitted signals to a transistorized "computer" behind the glove box. The computer controlled a vacuum-operated valve on the rear brake line to modulate pressure to the rear brakes when the sensors told the computer that the brakes were locking. At the time, these were considered too expensive for the marketplace, but over time, as computer technology became more efficient, antilock brakes became a standard part of most automobiles.
Brake technology is still being updated to this day, with computers and higher-quality parts being added to help make brakes stronger and more efficient. Of course, to make sure your brakes work consistently, it's important to have them checked up on a regular basis...and to make sure that you drive safely, so that you have to use them as little as possible.

Popular Electronics
Popular Electronics was an American journal commenced by Ziff-Davis Publishing in October 1954 for hobbyist and experimenters in electronics. It before long became the "World's Largest-Selling Electronics Magazine".
The circulation was 240,151 in April 1957 and 400,000 by 1963. Ziff-Davis issued Popular Electronics until April 1985. Gernsback Publications procured the label in 1988 and renamed their Hands-On Electronics. That variety of Popular Electronics was issued until December 1999.
A cover narrative on Popular Electronics could launch a new wares or company. The most renowned subject, January 1975, had the Altair 8800 computer on the cover and this ignited the dwelling computer revolution. Paul Allen presented that subject to Bill Gates. They drafted a BASIC interpreter for the Altair computer and commenced Microsoft. Radio & Television News was a journal for professionals and the advisers desired to bring ahead a journal just for hobbyist.
Ziff-Davis had commenced Popular Aviation in 1927 and Popular Photography in 1934 but encountered that Gernsback Publications had the trademark on Popular Electronics. It was a employed in Radio-Craft from 1943 until 1948. Ziff-Davis paid for the trademark and commenced Popular Electronics with the October 1954 issue. Many of the advisers and authors worked for both Ziff-Davis magazines. Initially Oliver Read was the reviser of both Radio & Television News and Popular Electronics. Read was endorsed to Publisher in June 1956.
Oliver Perry Ferrell took over as reviser of Popular Electronics and William A. Stocklin became reviser of Radio & Television News. In Radio & video News John T. Frye drafted a convey on a fictional mend shop where the proprietor, Mac, would merges with other technicians and customers. The learner would study mend procedures for examining broadcasting and TVs.
In Popular Electronics his convey was about two high school male offspring, Carl and Jerry. Each month the male offspring would have an escapade that would lecture the learner about electronics. By 1954 erected structure audio and broadcasting kits was a growing pastime. Heathkit and more other people proposed kits that embraced all of the elements with in actual instructions. The premier cover presentations the assembly of a Heathkit A-7B audio amplifier.
Popular Electronics would offer endeavours that were assembled from scratch; that is, the separate a person elements were paid for at a impeded electronics warehouse or by conveyed item order. The early subjects often presented these as male parent and teenager projects. Most of the early endeavour employed vacuum tubes; transistors had just become obtainable to hobbyist.
The Raytheon CK722 transistor was $3.50 in the December 1954 subject while a 12AX7 dual triode tube was only $0.61. Lou Garner drafted the aspect narrative for the first subject, a storage battery propelled tube toyota spare parts, Locomotive Parts broadcasting that could be employed on a bicycle. Later he was bestowed a convey called Transistor Topics (June 1956). Transistors before long cost less than a dollar and transistor endeavour became universal in every subject of Popular Electronics.
The convey was renamed to Solid State in 1965 and ran under his byline until December 1978. As Editor, Olivier Ferrell assembled a unwavering of authors who augmented fascinating makeup projects. These endeavours established the approach of Popular Electronics for years to come. Two of the most prolific authors were Daniel Meyer and Don Lancaster. Daniel Meyer graduated from Southwest Texas State (1957) and became an practical operator at Southwest Research Institute in San Antonio, Texas. He before long commenced drafting hobbyist articles.
The first was in Electronics World (May 1960) and second cited he had a 2 part cover aspect for Radio-Electronics (October, November 1962). The March 1963 subject of Popular Electronics embraced his ultrasonic assuming innovation on the cover. Don Lancaster graduated from Lafayette College (1961) and Arizona State University (1966). A 1960s fad was to have guarded with sunshade of colour lights synchronized with music.
This psychedelic lighting was made economical by the development of the silicon-controlled rectifier (SCR). Don's first issued part was "Solid-State 3-Channel Color Organ" in the April 1963 subject of Electronics World. He was paid $150 for the story. The endeavours in Popular Electronics altered from vacuum tube to solid state in the early 1960s. Tube circuits employed a metallic chassis with sockets, transistor circuits worked best on a issued circuit board. They would often encompass constituents that were not obtainable at the impeded electronics elements store.
