The design of the calipers of modern vehicles provides for two pads and a bracket. One pad rests to the side, the second moves along the guides under the influence of the caliper piston, which presses on the movable pad. It is pressed tightly against the plane of the disk. The floating caliper bracket begins to move towards the piston directly along the guide pins. The outer pad is also pressed against the brake disc itself.

The MEYLE brand Guide Bolt, brake caliper is represented by a pin and is designed to ensure the movement of the movable component along the centerline. Such a structural element consists of a steel cylinder and a tip having an internal thread.

Often one or more plastic or rubber rings are also provided. A buffer is used to protect the installation site. It prevents the lubricant from being washed out, as well as the penetration of dirt directly into the workspace. Wear of the buffer leads to volatilization of the lubricant, clogging of the deaf, working cavity. Lack of lubrication is fraught with wear of the guide bolt metal. In this case, motorists hear a frequent knock when driving over bumps. The guide bolt on the seat starts a certain mobility.
