Claims

[Scope of utility model registration request]

a caliper; a piston slidably mounted on the caliper and pressing the friction pad against the disk;
A nut provided on the piston, a push rod having a multi-thread thread screwed into the nut on the tip side and sliding the piston through the nut when operating the manual brake, and a push rod with the push rod on the non-braking side In a disc brake consisting of a spring that biases the spring, a spring holder that supports one end of the spring, and a retaining ring that fixes the spring holder to the caliper, the nut may be replaced when disassembling and assembling the disc brake. The push rod is used for compressing a spring through the spring holder, and is characterized by being comprised of a female threaded portion that is screwed onto a multi-thread thread of the push rod, and an elastic body that comes into frictional contact with the multi-thread thread. Jig for disassembling and assembling disc brakes.
