The failure on the brake shoes also can be found in the braking system, the brake shoes designed to wear first, and more intervals to take maintenance than the disk. There are various ways to improve the performance of brake shoes. The improvement carried out to increase the ability to released heat and the ability to endurance again the friction (Abutu et al., 2018). The biggest challenge in the development of brake shoes is resistance to high temperatures (Zhang et al., 2020). Changing the material used will help to increase the durability of the brake shoes used (Matějka et al., 2017). The brake shoe placement is shown in Fig. 2.

3. Influence of technical fracture to vehicle accident The failure of the braking system causes many vehicle accidents. Excellent braking can reduce the risk of accidents (Pawar et al., 2020). One of the factors that cause damage to the braking system used is due to too much weight received by the brakes (Kamla et al., 2019). There are many reviews on the analysis of the causes of accidents, and in all these studies it has always been stated that the failure of the braking system is one of the main factors (Ghaleh et al., 2019; Kamla et al., 2019; Pawar et al., 2020; Rainey et al., 2019). Therefore, it can be concluded that the braking system is very influential in driving safety. Vehicle speed also affects the number of braking system failures. Often vehicle drivers tend to go fast and do rapid deceleration, which is done repeatedly (Dubos, Varin, and Bisson 2016). The improved braking performance will be able to provide a sense of security and calm when driving. This situation occurs because the brake system is the most straightforward safety system. When there is damage to the brake components, this will affect the ability to stop the vehicle's speed (Zou et al., 2011).
