“…The braking system is a crucial element of safety necessary for the safe use of the vehicle (Jegadeeshwaran and Sugumaran, 2015). In the literature, there are many works in the field of testing of friction elements of braking systems (Indira et al, 2015;Pavlov et al, 2015;Sawase and Sano, 1999;Sergienko et al, 2013;Walczak et al, 2015), and work on testing of operating fluids: fuels and engine oils (Sejkorova, 2013;Sejkorova and Senkyr, 2017;Valiś et al, 2018). However, relatively few of them relate to brake fluids, hence deserving the attention of research (Bzura, 2007;Kuranc et al 2018;Jakóbiec, 2006;Lee, 1999;Sejkorová et al, 2018).…”

During the operation of vehicles, the properties of liquids and consumables deteriorate, which may affect the level of safety of technical systems and road traffic safety. The results of testing brake fluid aging as a function of boiling point and percentage of water content were presented on a selected group of passenger cars. The tested vehicles were varied in terms of age and kilometer mileage. The methodology for testing the quality of brake fluid based on glycol selected passenger cars remaining in service has been presented. In this study was shown a significant decrease in the brake fluids quality during the two years of operation in vehicles. The determination of boiling point was more efficient than the determination of water content. Despite the lack of full vehicle operational information, the obtained test results allow for exciting observations.

“…Sergienko et al studied a dimensionless heat problem for a friction pair of a multidisc brake under conditions of a linear decrease in the friction power of discs with time. Thermal state of friction pairs of the multidisc brake under load and velocity conditions of the friction of the discs that simulate service braking of a wheel tractor was experimentally and theoretically studied [8]. Accounting for the initial decrease and the subsequent increase in the frictional forces with increasing relative velocity, Kaliyannan et al considered a negative gradient friction model and obtained approximate analytical expressions for the amplitudes and base frequencies of friction-induced stick-slip and pure-slip phases of oscillations [9].…”

For the serious and uneven wear of the brake pad in the high-power disc brake during braking, the dynamic variation of the brake disc and the brake pad interface variable is considered, the wear calculation model is established based on the friction and wear mechanism, and the wear depth and volume of the brake pad can be calculated by equations. A finite element model of the brake disc and the brake pad is established by DEFORM software which can analyze wear of the brake pad directly. The variation trend of wear during braking is studied, and influences of braking load and initial braking speed on the wear are analyzed. The results show that the amount of the wear increases rapidly in the early wear stage of braking, and it becomes slow in the later stage; the wear of the brake pad is serious at the friction inlet and outlet, and the middle area of the brake pad is lightly worn; heavy braking load and high initial braking speed can exacerbate the wear of the brake pad.

Providing the stability of the coefficient of friction of a vehicle disk brake under extreme operating conditions

et al. 2016

The authors propose a method of providing stability of the coefficient of friction of a disk brake. The method is based on the use of combination of friction materials in the force pattern of working elements of a disk brake. These friction materials interact with a brake disk and have individual level of loading. The article theoretically substantiates the possibility of the impact of the integral properties of a combination of friction materials involved in the force interaction on vehicle braking parameters. The reasonability of the proposed method is proved by the results of the experimental research. A brake-pad (lining) design has been developed to implement this method.
