The bicycle and its various components are well known in the prior art, and therefore, the bicycle 1 and its various components will not be discussed or illustrated in detail here. Rather, the bicycle 1 and its various components will only be discussed to the extent necessary to understand bicycle disc brake calipers 10A and 10B.

Basically, the bicycle frame F has a frame body FB and a front fork FF. The front fork FF is pivotally supported by the frame body FB to pivot about an inclined vertical spindle in the front portion of the frame body FB. Here, bicycle 1 is shown as a road bicycle. The bicycle 1 further includes a sunken handlebar H coupled to the front fork FF, and a saddle or seat S coupled to the frame body FB. The front fork FF rotatably supports the front wheel FW at the lower end of the front fork FF. The front wheel FW has a front brake rotor BR1, and the front brake rotor BR1 is attached to the hub of the front wheel FW so that the front brake rotor BR1 rotates integrally with the front wheel FW. The frame body FB rotatably supports the rear wheels RW, and the rear wheels RW are rotatably supported on the rear portion of the frame body FB. The rear wheel RW has a rear brake rotor BR2, and the rear brake rotor BR2 is attached to the hub of the rear wheel RW so that the rear brake rotor BR2 rotates integrally with the rear wheel RW. The bicycle 1 can be a mountain bicycle or an urban bicycle with a flat handlebar.

As seen in Figures 1 to 3, the bicycle disc brake caliper 10A is mounted on the front fork FF of the bicycle frame F, and the bicycle disc brake caliper 10B is mounted on the frame body FB of the bicycle frame F (ie, Chain stay). The bicycle disc brake caliper 10A is constructed to engage the front brake rotor BR1 in a conventional manner. The bicycle disc brake caliper 10B is constructed to engage the rear brake rotor BR2 in a conventional manner. Here, the bicycle disc brake calipers 10A and 10B are hydraulically operated. The bicycle disc brake caliper 10A is fluidly connected to the brake operating device BD by the first hydraulic hose H1, and the bicycle disc brake caliper 10B is fluidly connected to the brake operating device BD by the second hydraulic hose H2 . However, the bicycle disc brake calipers 10A and 10B can be mechanically (cable) operated.

As seen in FIGS. 2, 4 and 5, the bicycle disc brake caliper 10A basically includes a main caliper body 20 and a mounting structure 22. In the first embodiment, the bicycle disc brake caliper 10A is mounted on the front fork FF of the bicycle frame F via the mounting adapter 26. However, depending on the installation configuration of the front fork FF of the bicycle frame F, the installation adapter 26 can be omitted. For example, the bicycle disc brake caliper 10B does not use the mounting adapter discussed below. Here, the mounting adapter 26 is mounted to the front fork FF by a pair of fixing bolts 28. The fixing bolt 28 extends through a pair of openings 26a in the mounting adapter 26 to mount the mounting adapter 26 to the front fork FF.

With reference to Figures 2, 4 and 5, the main caliper body 20 will now be discussed in more detail. In the illustrated embodiment, the main caliper body 20 is a one-piece component. Alternatively, the main caliper body 20 can be two or more pieces attached together by bolts, adhesive, or any other suitable fastening method.

The main caliper body 20 also includes a hydraulic fluid inlet port 82 which is attached to the hydraulic hose H1 by using a conventional hydraulic hose connector C1 provided on one end of the hydraulic hose H1. For example, the hydraulic hose connector C1 of the hydraulic hose H1 can be a threaded hose connector, as shown in FIG. 2. Alternatively, the main caliper body 20 can be constructed with a hydraulic fluid inlet port which is constructed to receive a banjo bolt for fluidly connecting the hydraulic hose to the main caliper body 20. Here, the hydraulic cylinder barrels 66 and 68 are fluidly connected to the hydraulic fluid inlet port 82 via the inner fluid passages 84 and 86. The pistons 62 and 64 are biased away from each other by pressing the brake plates 70 and 72 outward against the biasing element 80 that pushes the pistons 62 and 64. Due to the pressure of the hydraulic fluid acting on the pistons 62 and 64 due to the user compressing the brake lever of the brake operating device, the pistons 62 and 64 are moved together. Preferably, although not shown, the main caliper body 20 also includes a fluid outlet port for receiving the discharge valve.
