I'm sure the quality is fine...
When Clutch fluid becomes cloudy and black, I think it is no problem to judge the deterioration of CylinderCup and Boots in Master Cylinder. As the relationship between Seal and Metal in Fork, Master Cylinder is full kit because of wear of Piston which is moving back and forth in Cylinder as well as Rubber which receives pressure every time lever is operated. However, I think the rubber parts deteriorate faster than others. So I was hoping that they would sell the rubber parts separately. However, it is not realized even if I wait and wait. I would like you to be flexible about this, DAYTONA.
