Abstract

PROBLEM TO BE SOLVED: To exchange the pad of a disc brake simply and quickly. SOLUTION: An intermediate member 8 is interposed between a piston 3 and a pad 5 and a groove 8b is installed on this intermediate member and the tip end of a lever 9 is inserted thereto and the tip end of this lever 9 is combined pivotingly with the intermediate member 8 by a pin 10 at the center part of the piston 3. In such piston push back mechanism 7, when the lever 9 is swung by adding a force to an operation part 9a, the tip end of the lever is displaced to the piston side and the intermediate member 8 as well as the piston 3 are pushed back. Therefore, the piston can be pushed back without removing the pad 5 and the work is simplified and quickened.

In the tool disclosed in the above publication, the pad is removed, the bag body is put in the gap formed between the disc and the piston, and the bag body is expanded by the pressure medium supplied from the outside. However, to remove the pad,
It must be rocked to create a suitable clearance between the pad and the disc and the pad and piston that are in close contact. After that, the work is proceeded by the procedure of removing the pad, inserting the tool, and feeding the pressure medium, so that there are some aspects that are not sufficient in terms of work efficiency and work time.
