This thesis research served the purpose of developing a safe, practical and accessible maintenance plan that would be able to reduce the chances of brake failure occurring in personal vehicles. The research involved the usage of the three out of the seven basic quality tools to evaluate and diagnose various brake component statuses in three different vehicle models: Peugeot 206, Chevrolet Matiz (2004) and BMW i3 (2015). A Check Sheet, Histogram and Ishikawa diagram were specially chosen as the three quality tools that would be used to document the results obtained throughout the whole examination procedures because of their ability to present data simply and clearly. The PDCA (Plan-Do-Check-Act) cycle phase provided a straightforward and organised guided approach that helped when it came to applying the three basic quality tools during the examination procedure of each vehicle's brake components. The examination was carried out by simple visual checks along with a vernier calliper that was specifically used when it was time to measure the brake pad and brake shoes thicknesses. At the end of the examination of the three vehicles' brake components, a strong conclusion was made that brake shoes and brake pads are the most vulnerable due to their quick wear and degradation characteristics [27]. The Peugeot 206 vehicle model elaborated the most severity rating for its brake pads and brake shoes, with brake pads scoring a 35% brake thickness percentage and brake shoes scoring a 38%. This low percentage in thickness meant that physical symptoms such as squealing noises when brakes are applied would be frequently audible and that the Peugeot 206 needed immediate repair. The Chevrolet Matiz (2004) vehicle model presented slightly more impressive results than the Peugeot 206 vehicle in terms of brake pad and brake shoe thickness ratings. Brake shoe thickness percentage was 50 % and the brake pad thickness was recorded to be at 54%, which meant that the physical symptoms the Chevrolet Matiz (2004) vehicle presented were not as severe as the ones of the Peugeot 206 vehicle that made squealing noises. The discoveries made from the conduction of this thesis research work can be supported better by reviewing and gathering similarities from a study that discussed brake pads in the Indian market, along with the crises of safety and environmental contamination. Their research work suggests that the use of low-grade brake pads such as the (AM) sample can result in extremely low and dangerous friction coefficients during a fade test which is conducted to analyse the thermal stability and brake pad performance of a vehicle. This directly explains the poor brake pad and brake shoe performances recorded in the Peugeot 206 brake component examination, by implications that suggest there were underlying issues present in the substandard components in the aftermarket. Furthermore, the external study material describes that there was a common appearance of asbestos, a commonly banned carcinogenic fibre in the aftermarket of brake pad types. This means that health risks are another problem that could surface on top of using terrible brake pad quality materials that can cause road accidents. The suggested preventive maintenance plan that was described in the previous chapter emphasizes the need for vehicle owners to use brake pads with good quality materials. And this action prescribed by the preventive maintenance table can help vehicle owners not to encounter harsh carcinogenic fibres that could potentially threaten their health and well-being in the long run [28]. The study also communicates that there is a strong possibility that there would be presence of heavy metallic metals such as copper in the debris of worn brake pads or brake shoes. As vehicles brake on the roads, this debris can be easily deposited and washed away into water bodies like rivers, oceans and lakes during the rainy season. The debris remnants that do manage to get into the water bodies will be a threat to aquatic life and cause severe intoxication to the natural Ph levels of the water, leading to future environmental hazardous damages. The suggested preventive maintenance plan continues to provide simple actions to prevent such scenarios from occurring, such as advocating for the need to regularly inspect brake pads and change them in due time before they are degraded severely enough to produce debris when braking is taking place [28]. Regarding this interconnected safety and environmental issues, this thesis strives to provide simplified approaches that can be easily conducted by anyone possessing a vehicle, to be able to identify a brake component that is prone to fail and take action to prevent further damage to the vehicles braking system and to the health of the vehicle owner and their environment. The external research document used for reference also explains the positive implications of standardized testing during procedures, which in connection to this thesis research study, establishes many preventive actions that can eliminate the chances of environmental pollution and increase vehicle safety. With the help of check sheets and Ishikawa diagrams, vehicle owners would now be able to clearly comprehend the root causes of brake pad and brake shoe wear in personal vehicles as well as they would also be able to perform proactive control methods by analysing physical symptoms that present when brake pads or brake shoes are beginning to fail. In summary to all that has been said from the comparison of the external research document findings and this thesis research study, it is safe to declare that brake failure in personal vehicles is not an event that can randomly occur but rather it is a predictable outcome of component wear and degradation that is manageable by applying the correct systematic approaches and clues. The future of safer braking systems in personal vehicles begins with the application of simple and well proven preventive maintenance plans being applied in a frequent mannerism to vehicles on a day-to-day basis. Such as the one suggested in the methodology chapter of this thesis study because it provides a well organised check sheet diagram that links components and their current conditions to suitable and easy actions that are advisable in accordance with the well conducted visual vehicle inspections. Future research work that might be conducted in the brake failure field, for mostly personal vehicles, should focus on sensor technologies to augment the visual inspection carried out.
