This paper deals with carry out the characteristics grasp experiment of elevator brakes. These experiments investigated the effects of surface roughness, oil and water of the test piece. In these experiments, the electromagnetic brakes of the disk type were used. Load is input to the test piece by using a hydraulic actuator. Further, it is a mechanism to measure the generated load by using a load cell. The result of the experiment provided the following findings. 1)Water increases the frictional force. Therefore, there is no worry to the wet. 2)Smearing of oil reduces the frictional force. As a result, when the oil is smeared even one time, it is necessary to replace the brake pad with new without fail. 3)Effects of surface roughness given to frictional force is small. Consequently, the conceivable risk is low. This paper is based on the result that carried out by the Ministry of Land, Infrastructure and Transport by "FY2013, the Building Standards Development Project for Promoting survey number: P6".
