ABSTRACT
The authors’ tests results on the impact of the guiding system (the guides) contamination in the friction lift on the delay of progressive gears braking process are presented in this article. The tests were conducted using a free fall method and a test bench built for that purpose. In order to render all working conditions the guiding system of tested gears was lubricated with the most commonly used lubricating agents. Solid grease (SM), mineral oil (OL), the mixture of solid grease and quartz sand (S50) as well as the mixture of mineral oil and quartz sand (O50) were used.
