Introduction of Light Vehicle

            The braking system of vehicles is often a subject under extensive legislative requirements and legislative frameworks. The braking system requires secondary and safe service for the failure of the system. The design and performance standards increase the service braking performance and characteristics of automotive brakes are complex. The performance of brakes is interrelated with the friction pairs (Howacarworks. com, 2018). The brake actuation is based on the braking system, brake performance, inertia dynamometer, and the temperature. The basic process of braking depends on the efficiency and functionality of the lever and pedal. The friction generated when the contact of material is developed in the wheel to slow and pressure that was applied. The present work is based on the analysis of the braking system and to analyze the material used in the development of brake materials (Mechanicalbooster. com, 2018).

Vehicle specification of Light Vehicle

Brake materials of Light Vehicle

            The braking system is composed of different components such as brake bands, brake shoes, brake blocks, brake lining, and brake pads. In the vehicles, different components are joined together to work effectively under the general guideline. The materials used to control the speed and to stop the vehicle is interlinked with the number of factors (Jang, Wang, & Chung, 2013). The materials resist wearing effects that occur due to galling and ablation process. The braking system generates heats and temperature of the material in this process changes due to higher heat capacity and thermal properties in the conductivity (Jang, Wang, & Chung, 2013).

Components of braking materials of Light Vehicle

        The typical braking system in vehicles is composed of many components and subsystems such as brake pedal, master cylinder, flexible hose, and wheel cylinder. All the parts are under potential risk for the functionality and manufacturing of variables in the designs. The main components of the wheel cylinder are cup seal, cylinder body, cup ex panders, screw and dust boots (Jang, Wang, & Chung, 2013)

                           .

Actual vs manufacturer specified the measurement of Light Vehicle

The braking system under the higher pressure faces issues of functionality. When the braking system is exposed to environment, dust, and moisture the capabilities of the system decreases. The maintenance of the braking system is essentially required to be continued. Rough and textured materials are used to increase the friction and efficiency of friction (Mechanical booster. com, 2018). In the manufactured braking system, the components are under higher pressure and low friction for the materials such as steel, cast iron, ceramics, and brake shoe caliper. The qualities of the system improve due to amalgamations, friction resistance, fiber formation, and other properties. The brake materials are often attached to the metal bases and increase constant functionality (Jang, Wang, & Chung, 2013).

Conclusion  on Light Vehicle

The fundamentals of the effective and efficient braking system are discussed in the present work. The purpose of the present work was to ensure the technical specification for the maintenance of braking equipment. The basic requirement for the higher performance of the braking system is based on the stability of components. The potential components are discussed under the comprehensive performance framework. The specified functioning of all the components is provided by the company to improve the braking system. The present work analyzed that the modified braking system under new technology is according to the world known standards and it can be improved by taking initiatives.

The slotted and drilled brake rotors are composed of ceramic pads and the advantages are provided by the holes drilled in both components for cooling process and to sweep the gas and dust from the components (Haynes. com, 2018; Howacarworks. com, 2018).

Change in brake pads of Light Vehicle

The slotted and drilled rotors increase the braking performance and at the same time reduce the brake fade. Both the rotors and the pads used in the brake system will have to wear out that will reduce a lot of stress during the braking process (Jang, Wang, & Chung, 2013).

OHS requirements of Light Vehicle

OHS requirements include occupational health and safety laws for the employees in the workplace. The laws are also designed to consult the management and risk associated with the workers and provide them the safe environment of work (Jang, Wang, & Chung, 2013). In the slotted and drilled rotors, the performance of the braking system improves and the probability of accidents due to high speed reduces. In such a way the braking system is according to the requirement of customers as well as WHS / OHS (Jang, Wang, & Chung, 2013).

Labor time and customer time of Light Vehicle

The process of replacement requires significant time and energies. The average standard cost of replacement of slotted and drilled rotors is $ 406 and $ 559. The labor cost is estimated at $ 158.  And the price of parts is about $ 248 (Mechanical booster. com, 2018).

Conclusion of Light Vehicle

The present work deals with methods used to improve the performance of slotted and drilled rotors and how it can be replaced with an ordinary system to improve the performance. The analysis suggests that labor cost of replacement is lower and the process improves the efficiency of the brake system in the vehicles. The represent report have significant real world applications and methods are approved by WHS and OHS.
