Definitions Brakes and associated brake lining <\/strong><\/p>\n1 from Singh Reyat<\/p>\n
\u201cThese are mechanical devices which use the force of friction to overcome friction. The brakes in an automobile, stop it while moving and hold it from rolling when not in motion<\/p>\n
When the brakes are applied on a moving vehicle, the kinetic energy or energy of motion of the vehicle is transformed into heat generated by the friction between the brake lining and drums.<\/p>\n
The heat generated is dissipated into the surrounding air.<\/p>\n
2 from Hillier and Pittuck,<\/p>\n
\u201cA moving vehicle possess energy of motion which must be converted into some other form of energy in order to bring the vehicle to rest .The speed of conversion governs the rate of retardation of the vehicle \u201c<\/p>\n
See appendix 2 below<\/p>\n
\u201cThe force of friction or retarding force between the linings and the drums depends upon the coefficient of friction of the two materials and the force exerted on the shoes by the retarding mechanisms \u201c<\/p>\n
\u201c<\/strong>Modern braking systems employ either a rotating drum or disc, the necessary friction is obtained by pressing a stationary shoe or pad against the rotating member\u201d<\/p>\nFerodo Company Profile \/Abbreviated summary <\/strong><\/p>\nKettlewell writing in early 80\u2019s<\/p>\n
\u201cBack in 1897 a Manchester manufacturer\u2019s agent named Frood founded the brake lining industry.<\/p>\n
The word Ferodo ,<\/em> was an anagram of his name with one letter added to make it pronounceable \u2026.early experiments\u2026 led his to filing a patents in 1900<\/p>\nOne of the early contracts was with the London General Omnibus Company\u2026.<\/p>\n
With the development of more sophisticated machinery came the inevitable higher speeds and a requirement for brake linings with greater heat resistance\u2026<\/p>\n
New materials known as Ferodo MR and MZ provide adequate for racing until the war \u2026<\/p>\n
During the late 1930\u2019s the duel for the World Land Speed Record resulted in an entirely different material being produced to meet the enormous braking demands of these fantastical fast and heavy vehicles \u2026VG 91also proved invaluable for tanks during the war..<\/p>\n
One of the most significant development of the post war racing was the introduction of the disc brake. For which an entirely new friction material was developed\u2026<\/p>\n
The Ferodo research organization the largest of its type in the world has managed to keep one step ahead of the demand. Profiting from lessons learned in their unrivalled racing experiences.<\/p>\n
All Ferodo materials owe much to the company\u2019s long association with motor sport \u201c<\/em><\/p>\nIn the Chapman\/Lotus era the Company was identified with brake lining suitable for temperatures up to 900degree F, clutch inserts anti fade brake material and pads.<\/p>\n
Ferodo Gold Trophy <\/strong><\/p>\nThis annual award was made twice to Colin Chapman\/Lotus.<\/p>\n
See our dedicated article Man of Letters <\/em>for details.<\/p>\nNote also Ludvisgen covers it in his book.<\/p>\n

- Study a British car specialist like Morgan, TVR, Ginetta or Lotus where do they source parts? What are the advantages?<\/li>\n<\/ul>\n
Exhibitions, Education, Economics and Entertainment<\/strong><\/p>\nIn the museum context the editors believe that commercial considerations are both necessary and complementary with its educational objectives.<\/p>\n
For these reasons our suggested outline Business Plan includes provision for promoting products and services which share Chapman\u2019s ideals of mechanical efficiency and sustainability. In addition we propose merchandising that explain and interprets the social and cultural context of Chapman\u2019s designs in period. It\u2019s suggested there will be catalogue for on line purchasing.<\/p>\n
In this instance we suggest the following exhibition titles might be appropriate:-<\/p>\n

<\/p>\n Figure 8 editors sketch of disc brake system Lotus 79<\/p>\n Conclusion: \u201cThe whole is greater\u2026\u2026\u2026\u201d<\/strong><\/p>\nThere can be little doubt about the significant contribution made by Ferodo.<\/p>\n They assisted Lotus achieve multiple F1 World Championships and probably other events for the sports racing cars.<\/p>\n Ferodo possible confirms the importance of patents.<\/p>\n It\u2019s important that archives for our national motor industry are kept for on going research.the editors were unable to access these due to lockdown but we recommend subscribers do so at future date.<\/p>\n Components were material to reliability and competitiveness.<\/p>\n Chapman\u2019s design and manufacturing methodology rather confirms the adage that \u201cthe whole can be greater than the sum of the parts\u201d.<\/p>\n It\u2019s an interesting an important study to consider deployment of components. It contributes to aesthetics, assembly economics and sales [attractive components\/ known accepted performance and servicing ability etc.]<\/p>\n It is equally and mutually relevant and beneficial to the component manufacturer.<\/p>\n Chapman and his colleagues often took the best \/ most appropriate mass produced item and almost reinvented it in its service to design objectives. In this manner many components acquired a new status and indeed their aesthetic was enhanced surrounded by the Chapman conceptual whole.<\/p>\n It\u2019s also extremely significant how many of these components were also used in Lotus competition cars. This created a powerful dynamic and interrelationship. Many components:-<\/p>\n \n- Performed well in competition gaining beneficial publicity and sales<\/li>\n
- Both the component and racing reputation carried through to road cars and assisted sales<\/li>\n
- The component manufacturer gained disproportionate publicity and assisted products sell in other applications<\/li>\n
- All together a beneficial spiral was commenced. Publicity of the era often opted to highlight the Lotus dimension in publicity material. In fact there was a powerful synergy.<\/li>\n<\/ul>\n
The relationship between Lotus and is sponsor specialist suppliers is significant and worthy of close study and has lessons for Engineering, Industrial Design and Manufacturing disciplines.<\/p>\n Along the way it\u2019s possible too to study the wider British motor component industry and how it has helped foster the specialist car manufacturers.<\/p>\n Sponsorship is a worldwide phenomenon of immense commercial impotence. Both to host and sponsor organization.<\/p>\n With the Passage of time it\u2019s likely to become more sophisticated and focused and the internet \/multimedia technology will play greater role.<\/p>\n Sponsors have existed in motorsport before Chapman but he vigorously exploited the concept with Gold Leaf c 1967\/68 and set a pattern for others to follow.<\/p>\n Sponsors of Lotus were likely to benefit financially and in terms of exposure to an extent greater than their investment. The benefits were, and remain essentially similar to present day:-<\/p>\n \n- Access to mass international audience consistent with mass production distribution marketing branding etc.<\/li>\n
- Demographics of viewing audience and interest groups<\/li>\n
- Additional subsidiary \/secondary advertising through media, news, magazines etc.<\/li>\n
- Identification with market \/brand \/marque leader in both F1 and road cars<\/li>\n
- Association with success and continuity evolving, developing technology, materials etc.<\/li>\n
- In period the identification with the charm ,charisma and ability to articulate that Chapman possessed<\/li>\n
- All the attendant glamour , drama ,danger ,and spectacle of F1<\/li>\n
- Ability to provide conducive hospitality to conduct business<\/li>\n
- Cost effectiveness of audience cost ratio<\/li>\n
- Possible further complex corporate benefits<\/li>\n<\/ul>\n
