The embodiments will now be explained with reference to the drawings. For those familiar with the bicycle field from this disclosure, it will be clear that the following embodiments are only provided for illustration and not for the purpose of limiting the present invention defined by the scope of the attached patent application. In this context, the following description describes a disc brake caliper installed on the frame 1000 of a bicycle (as an example of a human-powered vehicle). However, it should be understood that the disc brake caliper can be installed on any other human-powered vehicle. In addition, this example shows the disc brake caliper 10 installed on the chain stay 1001 of the frame 1000, so it is a part of the rear disc brake. However, the disc brake caliper 10 can also be mounted on another structural element of the frame 1000, such as a front fork rotatably arranged on the frame 1000, which is a part of the front disc brake. If the terms "front, back, top (top), bottom (bottom), left and right" are mentioned below, these terms refer to the state in which the disc brake caliper is installed on a human-powered vehicle (especially a bicycle frame). The rider of the vehicle is sitting and facing the handlebar (front). The disc brake caliper 10 includes a caliper body 12. The caliper body 12 is divided into a first part (first half) 12a and a second part (second half) 12b (refer to FIG. 5). The caliper body 12 can be installed in a human-powered vehicle, which in this example is the chainstay 1001 of the frame 1000 of a bicycle. For this purpose, the caliper body 12 contains a mounting surface 14 which is arranged at the mounting side 16 of the caliper body 12 facing the human-powered vehicle (see FIG. 7). In one example, the mounting surface 14 may be configured on the first portion 12a of the caliper body 12 (see FIGS. 5 and 7). The first mounting hole 18 defines a first mounting axis 18a. The first mounting hole 18 is provided on the mounting surface 14 for mounting the caliper body 12 to the human-powered vehicle via the first mounting member (refer to FIGS. 5 and 7). The first mounting hole 18 defines a first mounting opening 18c in the mounting surface 14. The first mounting member may be the bolt 20. The first mounting hole 18 includes a threaded hole 18b for receiving the bolt 20 as a first mounting member. The second mounting hole 22 defines a second mounting axis 22a. The second mounting hole 22 is provided on the mounting surface 14 for mounting the caliper body 12 to the human-powered vehicle via the second mounting member (refer to FIG. 5). The second mounting hole 22 defines a second mounting opening 22c in the mounting surface 14. The second mounting member may be the bolt 24. The second mounting hole 22 includes a threaded hole 22b for receiving a bolt 24 as a second mounting member. The mounting surface 14 includes a first part 14a and a second part 14b, wherein the second part 14b is separated from the first part 14a (refer to FIG. 7). Therefore, the first part 14a and the second part 14b are separated, and a space 34 is formed between the first part 14a and the second part 14b (refer to FIGS. 1 and 4). In particular, the first mounting hole 18 and the second mounting hole 24 are provided in the first part 14a and the second part 14b, respectively. In this example, the mounting surface 14 (the first part 14a and the second part 14b) is on the upper side of the chainstay 1001 of the frame 1000 facing the frame mounting surface 1002 (see FIGS. 1 and 5). Furthermore, the frame mounting surface 1002 is divided into a first part 1002a and a second part 1002b corresponding to the first part 14a and the second part 14b of the mounting surface 14 of the caliper body 12. In order to install the disc brake caliper 10 on a human-powered vehicle, the bolt 20 as the first mounting member and the bolt 24 as the second mounting member are inserted from below to the through hole 1003a in the chainstay 1001 of the frame 1000 And 1003b, and are screwed into the threaded hole 18b of the first mounting hole 18 and the threaded hole 22b of the second mounting hole 22. When locked, the bolts 20 and 24, the first part 14a and the second part 14b of the mounting surface 14 come into contact with the frame mounting surface 1002, especially the first part 1002a and the second part 1002b (see FIG. 5). As a result, the disc brake caliper 10 can be reliably fixed to the human-powered vehicle. As will best be seen from Figure 3, the first mounting axis 18a and the second mounting axis 22a extend perpendicularly to the mounting surface 14, in particular the surfaces of the first part 14a and the second part 14b, respectively. In addition, the second mounting axis 22a is parallel to the first mounting axis 18a. In addition, the surface of the first portion 14a and the surface of the second portion 14b may be parallel. In addition, the disc brake caliper 10 includes a first piston 26, which is movably disposed on the caliper body 12 along a first piston axis 26a that is not parallel to the first mounting axis 18a in response to the hydraulic flow from the hydraulic hose 100 (Refer to Figure 5 and Figure 6). In the illustrated embodiment, the first piston axis 26a is perpendicular to the first mounting axis 18a, and therefore perpendicular to the second mounting axis 18b, and the assembly axis 56a described later. The disc brake caliper 10, and more particularly the second part 12 b of the caliper body 12, may include a first piston cylinder 28. The first piston 26 is accommodated in the first piston cylinder 28 and is movable along the first piston axis 26 a in the first piston cylinder 28. The first piston ring 30 is disposed in a groove 28 c between the inner peripheral wall 28 a (the housing of the cylinder) of the first piston cylinder 28 and the outer peripheral surface 26 b of the first piston 26. Therefore, the first hydraulic chamber 32 is defined between the inner surface 26c of the first piston 26 and the bottom 28b of the first piston cylinder 28 (refer to FIG. 6). The outer surface 26d of the first piston 26 opposite to the inner surface 26c is in contact with the first brake pad 36 having the first support platen 36a. The first support pressing plate 36a supports the first brake shoe 36b. In addition, the disc brake caliper 10 includes a second piston 38 which is movably disposed on the caliper body 12 along a second piston axis 38a that is not parallel to the first mounting axis 18a in response to the hydraulic flow of the hydraulic hose 100. The second piston axis 38a is coaxial with the first piston axis 26a. The disc brake caliper 10, and more particularly the first part 12 a of the caliper body 12, may include a second piston cylinder 40. The second piston 38 is accommodated in the second piston cylinder 40 and can move along the second piston axis 38 a in the second piston cylinder 40. The second piston ring 42 is provided between the inner peripheral wall 40 a (the housing of the cylinder tube) of the second piston cylinder 40 and the outer peripheral surface 38 b of the second piston 38. Therefore, the second hydraulic chamber 44 is defined between the inner surface 38c of the second piston 38 and the bottom 40b of the second piston cylinder 28 (refer to FIG. 6). The bottom 40b is formed by a cover 40d, and the cover 40d is detachably fixed to the first part 12a of the caliper body 12. The outer surface 38d of the second piston 38 opposite to the inner surface 38c is in contact with the second brake block 46 having the first support pressure plate 46a. The first support plate 46a supports the second brake shoe 46b. The block spacer 48 is provided between the first brake block 36 and the second brake block 46 that are in contact with the first support press plate 36a and the second support press plate 46a. The block spacer 48 is an elastic spring member that forces the first brake block 36 and the second brake block 46 to move away from each other. In order to facilitate maintenance, especially the replacement of brake pads, the first brake pad 36, the pad spacer 48 and the second brake pad 46 are releasably fixed to the caliper body 12 by the pin 50. As best seen from FIG. 5, the pin 50 passes through the first part 12 a of the caliper body 12, the second supporting platen 46 a, the block spacer 48, the first supporting platen 36 a and the second part 12 b of the caliper body 12. The pin 50 is fixed in position by the clamp 52. When the clip 52 is removed, the pin 50 can be removed, and the first brake block 36 and the second brake block 46 can be replaced. In addition, the caliper body 12 also includes a receiving slot 53 which is constructed to receive the disc rotor 103 of the disc brake of the human-powered vehicle (see FIGS. 1, 2 and 8). The receiving slot 53 is formed between the first part 12a and the second part 12b of the caliper body 12. The first brake block 36 and the second brake block 46 are disposed in the receiving slot 53, and the disc rotor 103 is disposed between the first brake shoe 36a and the second brake shoe 46a (refer to FIG. 8). In addition to the mounting surface 14, the caliper body 12 further includes a mounting surface 54 which is disposed on the mounting side 16 offset from the mounting surface 14. Furthermore, the caliper body 12 includes a hose fitting hole 56 for attaching the hydraulic hose 100. The hose fitting hole 56 defines a fitting axis 56a. In addition, the hose fitting hole 56 defines a hose fitting opening 56 b in the fitting surface 54. In addition, a hose fitting hole 56 is provided on the fitting surface 54. Therefore, the hose fitting hole 56 is provided at the mounting side 16 of the caliper body 12 to be offset from the mounting surface 14 in the direction of the first piston axis 26a. In particular, the mounting surface is configured at the first part 12 a of the caliper body 12, and the mounting surface 54 and the hose mounting hole 56 are configured at the second part 12 b of the caliper body 12. Therefore, the receiving slot 53 is located between the mounting surface 14 and the hose fitting hole 56. The assembly axis 56a extends substantially perpendicular to the mounting surface 14 when viewed in the direction of the first piston axis 26a (refer to FIG. 3). The term "substantial" in this context covers a deviation of ±5° from vertical orientation. In addition, the assembly axis 56a and the plane P passing through the center of the receiving slot 53 (refer to FIGS. 6 and 8) do not cross. Here, the mounting surface 14 and/or the mounting surface 54 may be configured to be perpendicular to the plane P. Furthermore, the hose fitting hole 56 is provided so that the fitting axis 56a does not cross the first fitting axis 18a when viewed in any direction. In one configuration, the hose fitting hole 56 is arranged so that the fitting axis 56a is parallel to the first fitting axis 18a (see FIG. 8). In addition, the hose fitting hole 56 is closer to the center plane 1004 of the human-powered vehicle than the installation surface 14 in the state where the caliper body 12 is mounted on the human-powered vehicle (refer to FIG. 8). In other words, the hose fitting hole 56 is provided on the inner side of the caliper body 12 facing the center plane 1004 of the human-powered vehicle. The hose assembly hole 56 also includes a threaded hole 58 configured to receive an assembly member for attaching the hydraulic hose 100 to the hose assembly hole 56. The fitting member is a banjo fitting bolt 60 for penetrating the banjo fitting 102 at one end of the hydraulic hose 100 and having a fluid passage constructed to be in fluid communication with the hose fitting hole 56. As previously described, the hydraulic hose 100 has a Huqin joint 102 at one of its two ends. The Huqin joint 102 is a ring shape member having an opening 104 in its inner peripheral surface. The Huqin joint assembly bolt 60 passes through the Huqin joint 102. As a result, the Huqin joint 102 can rotate around the Huqin joint assembly bolt 60 with the assembly axis 56a as the rotation axis. Therefore, by rotating the hydraulic hose 100 about the assembly axis 56a at its end containing the Huqin joint 102, the longitudinal orientation of the hydraulic hose 100 can be changed. The Huqin joint assembly bolt 60 has a smaller diameter portion 60b between the head 60a and the threaded end 60c (refer to FIG. 6). The smaller diameter portion 60b has a smaller diameter than the threaded end 60c and/or the head 60a. The threaded end 60c is received and fixed in the threaded hole 58. The smaller diameter portion 60b communicates with the opening 104 located in the inner peripheral surface of the Huqin joint 102. In addition, the Huqin joint assembly bolt 60 has a bottomed hole 60d that extends from the surface 60e to the smaller diameter portion 60b at the threaded end 60c. In addition, the smaller diameter portion 60b has an opening 60f communicating with the bottomed hole 60d in its outer peripheral surface. Therefore, hydraulic fluid can flow from the hydraulic hose 100 through the opening in the inner circumferential surface of the Huqin joint 102 in the space between the inner circumferential surface of the Huqin joint 102 and the outer circumferential surface of the smaller diameter portion 60b. The hydraulic fluid can also flow from this space to the bottomed hole 60d through the opening 60f, and finally to the hose assembly hole 56. In addition, the disc brake caliper 10 includes a hydraulic piping system 62 formed in the caliper body 12 for fluidly connecting the hose fitting hole 56 and thus the hydraulic hose 100 to the first hydraulic chamber 32 and the Two hydraulic chamber 44. The hydraulic pipe system 62 includes a plurality of pipes 62a to 62f, and is best seen from FIG. 6. In this regard, the duct 62d is integrated into the first bolt 64 used to attach the first part 12a of the caliper body 12 to the second part 12b. A second bolt 66 that does not include such a pipe may be additionally provided to fix the first part 12a and the second part 12b to each other. When operating the disc brake using, for example, a brake lever, hydraulic fluid is forced to pass through the hydraulic hose 100 (see above) into the hose fitting hole 56 via the Huqin joint. Subsequently, the fluid flows into the first hydraulic chamber 32 through the pipe 62a, and into the second hydraulic chamber 44 through the pipes 62b to 62f. As a result, the first piston 26 and the second piston 40 are moved toward each other along the first piston axis 26a and the second piston axis 40a in response to the hydraulic flow from the hydraulic hose 100 through the hydraulic pipe system 62. Thereby, the first brake shoe 36b and the second brake shoe 46b are pressed against the top disc rotor 103 to provide braking force. Modification example As previously indicated, the present invention is described with respect to a disc brake caliper installed on the chainstay 1001 of the frame 1000 of a bicycle. However, the disc brake caliper may also be installed on the front fork of the frame 1000 of the bicycle, especially the rear side of the front fork. In the above embodiment, the disc brake caliper 10 is directly mounted on a human-powered vehicle, particularly the frame 1000. However, it is also clear that an adapter or a base member disposed between the caliper body 12 and the human-powered vehicle is provided, so that the disc brake caliper 10 is directly mounted on the human-powered vehicle. More specifically, the caliper body 12 can be mounted on an adapter or a base member, and the base member can then be mounted on a human-powered vehicle, such as a frame 1000. More detailed content in this regard and how such a base member can be constructed can be obtained from US 9,347,505 B2, and the content of US 9,347,505 B2 (especially regarding the base member) is incorporated by reference in its entirety. The above embodiment has been described using two opposite movable pistons (the first piston 26 and the second piston 38) as so-called fixed calipers. However, it is also possible to implement a disc brake caliper with only one movable piston as a so-called floating caliper.
