“…Note that asbestos fibers are typically found in the polymeric matrix of brake pads, along with a variety of other compounds [ 8 , 9 , 10 ]. As shown in Figure 1 , kinetic energy is converted into heat energy during the brake system operation by friction between the rotor surface and the brake pads [ 11 , 12 , 13 ].…”

“…As seen in Figure 2 a–c, excessive thermal loading can cause judder (disc thickness changes), surface cracking, and severe wear on the contact surfaces. In addition, high temperatures can also cause brake fluid, seals, and other components to overheat, resulting in malfunctions in the braking system [ 11 , 12 , 13 ]. A brake absorbs energy with the help of friction force.…”

The braking system is a crucial element in automotive safety. In order for the braking mechanism to function effectively, the brake pads’ durability as well as quality are crucial aspects to take into account. A brake pad is a part of a vehicle that holds the wheel rotation so that braking can occur. Asbestos, which is harmful to human health, is a raw material that is recently being widely used as a material mixture for the manufacturing of brake pads. Many efforts have been made by researchers to find other natural alternative materials to replace the use of asbestos. Natural materials that have received much attention and research include coconut fiber, wood powder or flour, bamboo fiber, shell powder, etc. This review paper focuses on analyzing the main parameters that affect brake pad performance. The composition of filler and fiber types of reinforcement for polymer composites is discussed. Previous studies’ information on the fabrication and testing of brake pads are also highlighted. Furthermore, the findings of this review can provide researchers and academicians with useful information and points to consider for further research.

“…Recent work has shown that the age of the vehicle has an impact on the boiling point of the brake fluid and consequently on the increase of braking distance and stopping distance of a vehicle equipped with a hydraulic system. The results showed, in the event of emergency braking, a high temperature in the braking mechanisms (600 °C), combined with the hygroscopic property of the fluid, cause the formation of steam plugs (150 °C) and decrease therefore the effectiveness of the braking system [6]. This phenomenon is further accentuated by the ageing of the Algerian and global car fleet [7].…”

“…At the same time, the increase in the average age of the national vehicle fleet (NAP) in Algeria does not help the situation. Moreover, the degradation of the properties of the brake fluid overtime and the increase in stopping distances associated with it make matters worse [6]. Indeed, the NAP average age is 11.8 years with 58.71 % of the vehicles over 10 years old, and this despite an annual rejuvenation exceeding 400,000 vehicles in 2014 and, 176 300 new vehicles in 2017 [7,8].…”

The object of the research is the most important factors causing road accidents. This paper aimed to study the effects of this factors and their interactions on the stopping distance function. Understanding this function through simulation and comparing the results with mathematical models and experimental tests will help to reduce the number of road accidents. A large part of road accidents is linked to non-compliance with regulatory speed associated with vehicle braking system (grip, road and tires) and weather conditions. A speed measurement campaign on peri-urban roads was carried out to study driving behavior and compliance with speed limits in several Algerian cities. An experimental modelling of speed, anti-lock system, weather, grip and their interaction effects on the stopping distance of a vehicle using the experimental design method, combined with driving simulator tests was been conducted. The developments of experimental design with speed variation ranges (70 and 130 km/h) were necessary to study the influence of the various driving parameters on stopping distance. The mathematical model developed has been validated by the results obtained on the simulator. The experimental design method and simulator results were used to identify and define the important parameters that influence the braking distance. The results show that the stopping distance (SD) is mainly influenced by the vehicle speed (S), the weather conditions (M), and their interaction. The increase due to speed leads to an increase in the stopping distance with an estimated effect of 54.30 m. When the speed varies between its lower experimental level (70 km/h) and its higher level (130 km/h), it is estimated that the stopping distance will increase by 54.30 m. The analysis of the road speed measurement campaign, 55 % of road users do not obey the speed limits. The results obtained in this study can be applied to other countries, only the parameters need to be adjusted.
