A tool set for replacing brake pads of disc braking systems comprising:
- a screw rod having one end combined with a sliding handle and the other end provided with a coupling portion as well as a tapered plane;
- a sleeve capable of being extended through and screwed by said screw rod and having a hollow threaded passage formed therein as well as a flange formed at one end of said sleeve;
- a first plate body capable of being extended through by said screw rod and having a big-bore hole, a middle-bore screw hole and a small-bore hole orderly arranged from a center of said first plate body to one side of said first plate;
- a second plate body capable of being extended through by on one end of said screw rod and having a first hole, a second hole as well as a third hole orderly arranged from the center of the second plate body to one side of the second plate body with their centers respectively aligned with those of said big-bore hole, said middle-bore screw hole and said small-bore hole of said first plate body;
- a guide rod capable of extending through said small-bore hole of said first plate body as well as said third hole of said second plate body disposed at an outer end of said second plate body, said guide rod having a connecting portion disposed at one end for being fixed to said first plate body;
- at least one connector with different sizes each having an insert hole and at least one projection, said insert hole formed in a center of said connector and capable of being extended through by said coupling portion of said screw rod, said at least one projection disposed in a proper position on one surface of said connector for being correspondingly fitted into and engaged with at least one engagement groove located in a front surface of a piston;
- and,
- whereby a selective combination of said components described above is capable of providing an automobile with a specialized tool for pressing an outward piston to its initial position for convenient replacing new brake pads when said piston is gradually traveled toward old brake pads with a continuous wearing in linings of said old brake pads;
- moreover, various selective combinations of said components described above are also capable of providing automobiles employed with different types of disc braking systems with variety of suitable specialized tools fitting functional requirements and being convenient in operation, thereby achieving a high use rate and being convenient for storage.
