All the car accidents have huge economic and social problems. Revealing true accident reasons, fairness of the technical expertise upon car accident reconstruction is being a priority task. The result of the conducted research is experimental proof of additional factors influence to brake system response time. When conducting research measurements of the friction linings, braking force on front and rear axle are to be made. For the test a group of five technically sound vehicles with mileage from zero to thirty thousand km was selected. Experimental research of the brake systems operation was conducted at the production base of «Mega Motors Almaty» LLP and “Arystan-NLA” diagnostic center. Diagnostic equipment of BILANMATIC MULLER German firm was used for testing. Obtained measurement results such as: friction lining thickness, brake system response time with actual thickness of friction linings, force on brake pedal upon braking on front(rear) axle, brake force on front(rear) wheels allowed clearly understand that the rise time to maximum deceleration significantly influences the wear of the friction linings and the force amount on the brake pedal. More detailed understanding of the above-mentioned factors influence degree and their weightage on brake system response time can be the issue of further, more detailed research using approach probabilistic methods.
