Comparative study on the lateral run-out of friction surfaces measurement of brake discs using a brake roller tester and a dial gauge

Abstract

Abstract. Brake system diagnosis is one of the most common and necessary technical operations applied to the car, regardless of its type and operating phases. Measuring the diagnostic parameters on a roller brake tester is a fast operation with no disassembly necessary. Measuring the run-out of friction surfaces of brake discs with a dial gauge is an action that requires more extensive preparatory operations but it offers a high accuracy of the results. The paper aims to analyze the correlation between the dial gauge measured values and the diagnostic obtained using the brake roller tester.

Aspects of Measuring Brake Parameters on Heavy Trucks Using a Roller Brake Stand

“…The literature contains a significant number of articles dealing with the construction [1], operation [2,3] and analysis [3][4][5] of roller stands. However, there are quite a few studies that analyze the results obtained from the tests on the stand.…”

“…Using a roller stand, Toma M, et al, in the study [3], analyzes the effects of shoulder wear (lateral wear on the surface of the brake disc). A similar type of analysis was used for the current study, being the identification of some methods of analysis of wear starting from the results provided by the brake stand.…”

Evaluation of Service Brake Braking of Selected Group of Vehicles Depending on Wear of Brake System‘s Parts

“…The wear of friction components of the brake system, such as brake pads and discs, has a significant effect on the efficiency of the brake system, which is manifested in the stationary tests of the brake system (Mohammed et al, 2023). As a result of the significant wear of brake's components, there is a decrease in braking forces manifested in the tests of the brake system using a roller brake tester (Toma et al, 2017).…”
