Old Ford Drum Brake History and Tutorial

Old Ford Drum Brake History and Tutorial

Old Ford drum brake history and tutorial

Pre 1967 old Ford cars and old Ford trucks used a drum brake system. In these systems, pressure applied to the brake pedal is transmitted to the master cylinder, which in turn disperses the energy ultimately to the brakes in each wheel. The master cylinder uses the brake fluid to move the wheel cylinders, which in turn moves the brake shoes in the drum.

There is a front and back brake shoe, the rear one for stopping a vehicle in drive and the forward one for stopping a vehicle in reverse. When either shoe is pressed against the anchor pin, the brakes are engaged, and the vehicle comes to a stop. The brake pads form the shoes to the anchor pin so there is no slipping. The padding on the rear brake shoe is typically longer and sometimes made of a different material to allow the shoes to wear at a similar rate, since the rear shoe sees much more use.

The brake shoes are secured in the drum with both hardware and return springs, which must meet ideal sizing and tension specifications for your make and model for top brake performance. These parts should be replaced any time you work on the brakes in order to counteract wear and tear that can lead to longer stopping times.

Stock brake line hoses will have a rubber lining, while aftermarket hoses are available in a stainless braided wrap to preserve the hose. Whichever type you get, make sure the hoses are the correct thread size and length for your year and model and meet DOT safety standards. The rear wheel drum brakes will also contain the parking brake mechanism and will have a cable to the parking brake.

Brake pipe must be double flared and use flared nuts. It can be purchased with the flaring already completed or you can cut your own and flare it yourself, but it should meet or exceed DOT safety standards.

Hydraulic brakes will fail if there is a weak point in the system, so make sure all your hose and fittings are SAE rated and correctly installed. If you are unsure after installation, test the brakes at low speed in a safe area, such as your driveway or an empty parking lot before taking the vehicle on the road.

Starting in 1967 all old fords have a dual master cylinder. This part separates the wheel hydraulics of the front and rear of the car, so a failure in one will not cause a failure in the other. In vehicles without this feature, a leak anywhere in the brake line will cause the entire brake system to fail. With a dual master cylinder, a leak in the front brake system will not affect the rear and vice versa. This is standard in vehicles made after '67, but it's a good safety upgrade for older classic Fords as well.

Many classic Ford owners choose to upgrade their front brake system to disc brakes, or the complete system. Drum brakes can overheat and fail in high braking conditions, such as rapid stops at high speeds or driving downhill on mountainous roads. Disc brakes are open and exposed to the outside air, which prevents overheating and brake failure. While this upgrade is not strictly necessary, it's a good idea if you frequently drive in hilly or mountainous areas.

Original Ford brake shoes used asbestos in the brake pads. If you are working on a vehicle with its original brake shoes or if you are uncertain if they are original, wear a respirator rated for asbestos while working and wet the brake pads before opening the drum to prevent the asbestos from becoming air born. When cleaning dust from drum brakes, use a dense filtration system to trap the asbestos and dispose of it properly.

You can resurface a drum with minor surface issues, but make sure it stays within factory limits for your year and model. Worn or thin drums can break apart or crack and cause brake failure. If you see excessive wear and tear, replace the drum.

If you are replacing a leaking wheel cylinder, it's a good idea to do them all at once, including the master cylinder. If you have had problems with one, you will soon have problems with the rest. In addition, you won't need to remember which cylinder was replaced when for future maintenance if they were all replaced at once.

You can use a vacuum bleeder to remove old brake fluid and contaminants. Once you remove the old fluid you can use denatured alcohol followed by air to purge the lines. Vacuum each cylinder, including the master cylinder, and replace the old fluid with new, DOT 3 or 4 fluids. When changing fluid, change the rubber hoses and seals. If you have a combination disc and drum system, only use DOT 4 fluid. To ensure a complete cleaning, vacuum some of the new fluid through as well do catch any missed contaminants.

When working on or near the brake line, make sure no petroleum-based liquid, such as gasoline, oil, or mineral oil, encounters the hosing. These oils can break down the rubber and cause hoses to start leaking. Make sure to wash your hands thoroughly before and during working on the brakes system to prevent this, especially if you have been working on other parts of the vehicle.

When working on your brakes, make sure to follow safety precautions, use safety rated parts, and check over your work carefully. Drum brakes are a very important part of the machinery, and due to the hydraulic system, can easily lose stopping power or fail if something is wrong, especially without a dual master cylinder. Whether you're doing regular maintenance or upgrading the whole system, working carefully will ensure a successful job for your vehicle.

1950s Ford Cars and Trucks Evolution

1950s Ford Cars and Trucks Evolution

The 1950s marked a period of significant evolution for Ford Motor Company in both the automotive and truck sectors, characterized by engineering innovations and aggressive marketing strategies that aimed to capture the burgeoning post-war American market. Engineering Innovations: Starting with the 1949 models, Ford introduced a complete redesign that set the tone for the decade. This new line was characterized by more aerodynamic and modern styling, moving away from the pre-war designs. The Ford '49, as it was popularly known, featured a more integrated body design with smooth lines, which was a significant departure from the previous look. This design ethos continued into the 1950s, with each model year bringing incremental changes, but the 1952, 1955, and 1957 models were particularly notable for their styling advancements and engineering enhancements. The introduction of the overhead valve (OHV) V-8 engine in 1954 was a pivotal engineering achievement, leading to the launch of vehicles like the Thunderbird in 1955, which was Ford's answer to Chevrolet's Corvette. This engine was not only more powerful with its 181 horsepower but also set Ford apart in what became known as the horsepower race of the 1950s. The Fairlane Crown Victoria, introduced later in 1955, embodied luxury within the mid-price range, featuring this new V-8 engine alongside other engineering improvements like power steering and brakes, which became options in Ford's vehicles during this period. For trucks, the 1950s saw the further development of the F-Series, which had been introduced in 1948. The F-Series trucks evolved with the inclusion of a more robust chassis, new suspension systems, and eventually, the integration of V-8 engines, making them not only workhorses but also suitable for personal use. The F-100, in particular, became a cultural icon, known for its sleek design and versatility. Marketing Strategies: Ford's marketing in the 1950s was as dynamic as its engineering. The company leveraged the post-war economic boom, focusing on the American dream of owning a car. Ford capitalized on the new consumer culture by introducing vehicles that appealed to a wide demographic. The Thunderbird, for instance, was marketed not as a sports car but as a "personal car," emphasizing comfort and style over raw performance, aiming to attract both men and women. The introduction of models like the Edsel in 1958 was an ambitious marketing move. Named after Henry Ford's son, it was meant to fill the gap between Ford and Mercury in Ford's product lineup. Despite its innovative features like push-button transmission controls and a unique grille design, the Edsel was a commercial failure due to poor market reception, which highlighted the limits of marketing when not backed by consumer desire. Ford also pioneered safety features, introducing seat belts as standard in 1956, a move that was heavily marketed as part of Ford's commitment to customer safety. This era also saw Ford's advertising becoming more sophisticated, using television and print media to showcase their vehicles' modernity, performance, and styling. In summary, the 1950s were transformative for Ford. From engineering perspectives, the decade was about power, efficiency, and safety, while from a marketing standpoint, it was about capturing the spirit of an era filled with optimism and economic prosperity. Ford's vehicles during this decade not only shaped its destiny but also influenced the American automotive landscape profoundly.
FORD F100

FORD F100 HISTORY

FORD F100 HISTORY In 1953, Ford launched a fresh era of F Series pickups. The 1953 pickups were officially called F-100 and featured sleeker designs with an all-new cab and front end design. This generation of F Series pickups had larger measurements that included 55% larger windshield glass due to its curved design. With the wider cab you can seat 3 full size adults. 1953 Ford also improved chassis now available in 110” and 118” wheelbase (1948-52 is 114”). The gas tank was moved from behind the seat and now mounted on the outside of the frame below the driver’s side of the cab. The upgrades were designed to foster toughness and driving performance. The F Series pickups also took on new names. The F-2 became the F-250. The F-3 was renamed the F-350. Options included a dome light, cigarette lighter, ashtray, sun visors, radio, recirculating air heater and hot water heater. The new name was retained by the F-100 until Ford discontinued production of the F-100 after the 1983 model-year. In 1954 the all-new 239 CID "Y" block engine became available. The 1956 F-100 was celebrated for its perpendicular windshield pillars and its wraparound windshield. Available on the Custom Cab model is a wraparound rear window.

Ford also made approximately 101,000 to 184,000 models of the F100 in Sao Paulo, Brazil. SECOND GENERATION The second generation of the Ford F-100 ran from 1957 through 1960. The important styling change for this generation was a lower hood sitting flush on top of the front fenders. Ford launched its tradition of providing two different pick up box styles in this generation. Separate rear fenders were featured on the traditional Stepside design. The new released Styleside layout featured smooth sides as well as a far more streamlined look. New for 1958 was the use of four headlights, Ford continued this until 1960. In 1959, Ford began making the F-100 with a unique four wheel drive. Ahead of this new development, outside makers such as American and Marmon-Herrington and Coleman occasionally converted normal Ford trucks to four wheel drive. The next generation of the vehicles also marked an increase in sales of the optional eight-foot bed for the F-100, the typical length of the bed was six and a half feet. The eight-foot bed eventually eclipsed its smaller counterpart in popularity among F-100 motorists. Assembly continued to take place in the Ford plant in Dearborn, MI. THE 3RD GENERATION The new pickups were lower to the ground and wider than earlier versions. 1961 F-100 offered the optional uni-body, which combined the cab and box into one body. Ford discontinued the unibody design at the end of the 1963 production after it fared dismally in the marketplace. 1961 and 1962 Ford still used one piece hood side emblems. In 1963 new body side trim was now available on the styleside trucks with a red painted stripe in the center of the trim. The all new hood side emblem now included a plastic insert with the size of the truck “100”, “250”, “350”. In 1965 designers lowered the cab floor enhancing interior room. 1965 Ford also launched the first of its all new front suspension the "Twin I-Beam". 1965 Also offers a 352 "FE" motor instead of the “Y” block 292. The 6 Cylinder engine is also upgraded from the 223 to the new 240. Ford offered the Ranger option in 1965. The designation referred to your field of options that included an interior optional bucket seats with console and carpeting instead of a rubber floor mat. Ford changed some of its own assembly in this time to a plant in Cuautitlan, Mexico. FOURTH GENERATION Ford engineers continued their emphasis on pickups in 1967 that offered a degree of comfort which was similar to a car. 1967 Has new unique hood side emblems. 1967 offered new exterior trim, the body side trim is also new 1-1/4” wide with thin black line top and bottom as well as, available rocker trim. With the new designed cab now includes a new cargo light for the bed at the back of the cab above the rear window. 1968 Changed the hood side emblem to include a reflector. Lower bed side reflectors are standard. The exterior trim is now wider at 1-1/2” wide with the black thin line top and bottom. The Ranger option now includes a grille emblem. New for 1968 is interior door lock knobs. The exterior trim is changed again for 1970. The grille is all new with a plastic inert for either side of the grille. The front of the hood now has a trim going from side to side. The bed side reflector is moved from the lower bed side to the end of the body side trim and now has a light in it. The new Ranger and Ranger XLT trim is now 3-5/8” wide. The new wide trim is available with either black for the Ranger option or woodgrain for the Ranger XLT. 1971 The steering wheel is changed to a two spoke wheel with optional black or woodgrain horn pad. FIFTH GENERATION OF THE F100 AND INTRODUCTION OF THE F-150 The F-100 underwent major refinements for the fifth generation of the F Series, which ran from 1973 through 1979. Ford released the F-150, a fresh version, in 1973. The F-150 was essentially an F-100 with a spring package in the front and back that enabled the vehicle to carry a heavier load. Ford stopped production of the 4x4 F-100 in 1978. New grille with new plastic inserts for 1973 with the plastic insert now going around the headlight. The XLT option now included a grille emblem. The side trim was now available with a rubber insert down the center of the trim. The side reflectors now had light sockets with the front ones mounted in the front fenders and the rear still at the back of the bed trim. With the all new dash design trucks optioned with factory air conditioning now had vents in the dash for the air to go through and no longer was the air conditioning unit hanging from under the dash. 1974 Ford offered the new “Super Cab” with had a back bench seat and quarter windows behind the door. The new quarter windows were available fixed and with a pop out version. 1977 Offered a new exterior rim called “Race Trak” trim. The trim was a thin molding that started on the front fender at the grille and went down the side of the truck and curved up the bed side to meet the body side trim. Mid year 1978 Ford switch to square headlights which became standard for the F series trucks. Ford stopped producing the venerable F-100 entirely following the 1983 model year.
