Calculating How Many Particles Are Released Into the Environment When Car Brake Pads Are Worn

This article describes the procedures for calculating the quantity of particles discharged into the atmosphere due to brake lining deterioration during vehicle braking, accounting for the wheel's adhesion coefficient to the road. The quantity of particles that automobiles release into the atmosphere was determined theoretically, taking into consideration the fact that the resource period of brake pads varies based on the adhesion coefficient of the wheel with the road. Analysis of the metal concentration distribution in the particles created by brake lining wear during vehicle braking is extensively discussed. It was discovered that the car's brake samples included high concentrations of metal components such iron, copper, zinc, chromium, tin, and antimony. There is already information available regarding the harm that automobile brake particulates cause to the environment. A comparative examination of theoretic and experimental findings on the brake lining wear rate in relation to the road adhesion coefficient is showcased. The average wear speed of car brake pads varies depending on the adhesion coefficient of the road; this variation in wear speed has been proven by a comparative comparison of the theoretical calculation results.
