Both Front and Rear are scarcely replacing their products as they have little remaining quantity Quantity : 2pc. Purchase Set. Rear side installed without any problem Installation completed. Front side is ... That? S not it ... it does not enter? It seems that the outer diameter is too large and it is impossible to dock with Front wheel. Brake I was not grasping and the adjustment Bolt was loosened, but it did not enter at all. For the time being, Front side gave up for the time being, and when it decreases on the Rear side, it finishes the work by inserting it into the Front. I do not know whether it is a car body problem or a product problem, but Front - Because it was a notation with for Rear, too bad I purchase it. Those who are planning to replace please note once. I think that there is no particular problem in terms of performance.
