動液へＦＸｌｅＩ熱が伝わ−るのを防止している。In vehicle disc brakes, the temperature of the hydraulic fluid increases due to the W mechanism, which causes many I discs due to braking operations. In order to prevent vapor lock from occurring due to this, an insulator is installed between the piston that presses the para 1m plate of the friction pad toward the disk and the back plate of the pad, and the surface of the screw I/N is installed. This prevents FXleI heat from being transferred to the hydraulic fluid by coating it with ceramics.

る１に蒸熱を遮断しなければならなかった。However, the frictional heat of the disc that is transferred to the hydraulic fluid is transferred from the pad back plate to the inner wall of the caliper body in the area facing the disk, and more heat is transferred through the bridge part of the caliper body than through the piston. Vehicle disc brakes increase the effective diameter of the disc to increase the braking effect, so the diameter of the disc is made as large as possible, so the outer circumferential edge of the disc and the two parts of the caliper body are brought closer together. Frictional heat is radiated from the disc to the bridge section and transferred to the working fluid, so it was necessary to block the steam heat from being transferred to the working fluid through the bridge section of the caliper body.
そこで、本発明は制動操作によるｍ擦熱をプリリバボヂ

A dust seal 8 is interposed between the opening of the cylinder 4 and the piston 3 to prevent dust from entering. A corner seal 9 is interposed behind the dust seal 8 to seal the hydraulic fluid and provide return force to the piston 3.
