    • In a disc brake a piston is axially slidably mounted within a cylindrical space in a cylinder with an opening in the end of the cylinder communicating with the space. The piston is arranged to move axially through the opening and to press a friction pad into engagement with a disc. The piston is in sliding contact with the surface of the space in the cylinder body. A boot protector covers a boot extending between the inside of the cylinder body and the piston. The boot protector is formed, in part, of a rigid ring body fixed to the opening in the cylinder body in which the piston is housed and of an elastic ring body secured to the inner circumference of the rigid ring body. The boot protector covers the surface of the boot facing toward the disc. The boot covers the surface of the piston disposed in sliding contact with the surface of the cylinder.
    • 在盘式制动器中,活塞可轴​​向可滑动地安装在圆柱体中的圆柱形空间中,其中气缸的端部中的开口与空间连通。 活塞被布置成轴向移动通过开口并且将摩擦垫压入与盘相接合。 活塞与气缸体中空间的表面滑动接触。 靴子保护器覆盖在筒体的内部和活塞之间延伸的靴子。 保护罩部分地形成有固定在活塞容纳的缸体中的开口部的刚性环体和固定在刚性环体的内周的弹性环体。 靴子保护罩覆盖面向盘的靴子的表面。 靴子覆盖活塞的表面,其与气缸的表面滑动接触。
