After the internal and external brakes 23 and 24 are worn, the wear of the brakes increases the oil chamber 21 of the brake caliper 2 and the hydraulic oil of the chest 1 is increased for the brake caliper 2, so the total volume of the brakes is increased. The volume of the oil cup 11 needs to be sufficient to make a supplement of the liquid oil W. In particular, for a particular model, the oil cup 11 must be hidden in a vehicle body (not shown), and the oversized oil cup 11 is quite difficult to achieve the requirements of this 5 201031837 hiding property. SUMMARY OF THE INVENTION In view of the above, the present invention proposes a brake caliper that brakes a disc with a hydraulic oil. The brake caliper includes a cylinder, a piston, an intermediate member, a base, a chamber and a brake member. The piston is movably disposed in the cylinder. The intermediate component is coupled to the piston, and the intermediate component coupled to the piston and the piston are relatively movable. The base is movably disposed in the cylinder and in contact with the intermediate member. The chamber is disposed between the base and the cylinder, and the hydraulic oil system can be accommodated in the chamber. The brake element is disposed between the piston and the disk. When the hydraulic pressure is delivered to the chamber between the base and the cylinder, the hydraulic oil drives the base to move, and the base drives the intermediate member to push the piston, and the piston drives the brake member to brake the disc. The base includes a recess, and the chamber includes a recess of the base. When the hydraulic fluid is released, the brake disc drives the piston to move and the intermediate member is driven by the piston to rotate, thus increasing the distance between the piston and the base. The intermediate element and the piston are coupled to each other by means of a thread. The brake caliper may further include a bearing disposed between the piston and the intermediate member. The bearing is a ball bearing. [Embodiment] Fig. 3 is a view showing a brake caliper C, a brake master cylinder Ρ and a fuel pipe 3' of the present invention, wherein the brake master cylinder 利用 is connected to the brake caliper c by means of the oil pipe 3' and 6 201031837. The brake master cylinder P includes an oil cup u, an oil chamber 12, and a plunger 13, wherein the hydraulic oil W is stored in the oil cup u, and the oil chamber 12', and the plunger 13 is used to connect the oil chamber 12, the hydraulic oil w inside is output. The brake caliper C includes a cylinder block 4, an automatic adjustment mechanism inlet, a base 407 having a concave surface 4070, a chamber 408, and a brake element 6 having an inner cymbal 61 and an outer brake #62. The k body 4 includes a barrel-shaped cylinder wall 413, a claw portion 414 and an oil inlet hole 4081. The inner and outer brake plates 61 and 62 of the brake element 6 are disposed on the claw portion 414, and the automatic adjustment mechanism A0 and the base 407 are provided. It is disposed above the drum-shaped cylinder wall 413. The chamber 408 is a space formed between the concave surface 4070 of the base 407 and the cylinder block 4. The chamber 408 is connected to the oil chamber of the brake master cylinder P via the oil inlet hole 4081 and the oil pipe 3 of the cylinder block 4. 12'. The inner slide piece 61 has a projection 611. In the present embodiment, the chamber 408 includes a recess 407r formed by a concave surface 4070 of the base 407. The automatic adjustment mechanism A0 includes a C-shaped buckle 401, an elastic crest 402, a compression spring 403, an intermediate member 404, a ball bearing 405, a cymbal 406 and a piston 5. The central shaft portion 50 of the piston 5 has an internally threaded portion 51, and the intermediate member 404 has an externally threaded portion 4041. The C-shaped buckle 4 is used to sequentially position the spring seat 402, the compression spring 403, the spacer 406, the ball bearing 405, and the intermediate member 404 over the base 407. When the piston 5 is disposed in the drum-shaped cylinder wall 413 of the cylinder block 4, the internal thread portion 51 of the piston 5 and the external thread portion 4041 of the intermediate member 404 are engaged with each other. On the contact area between the piston 5 and the brake shoe 61 in the brake element 6, the projection 611 by the inner slide piece 61 can be used to restrict the piston 5 without causing a rotation. An oil seal 411 is sleeved between the circumferential surface 4071 of the base 407 and the cylinder wall 413 of the cylinder 201031837 4 by the oil seal 411 to prevent the hydraulic oil from undue leakage. Under the action of the plunger 13 of the brake (four) p, the hydraulic oil W in the oil chamber 12' of the crucible is conveyed to the chamber 408 ' between the base recording bodies 4 via the oil pipe 3 and the hydraulic oil w can be reused. Pushing the base, at this time, the base 407 pushes the middle jaw 404 against the elastic deformation of the oil seal 411, and the piston 5' sequentially drives the inner and outer brake pieces 61, 62 of the brake element 6 to clamp the brake charm 63. And achieve the role of braking. When the cool car is always! > After the liquid oil of the hydraulic oil W is released, the oil seal 411 pulls back the base, and the inner and outer brake pieces 61, 62 of the brake member 6 and the piston 5 are naturally released by the rotation of the brake disc 63, and the compression spring is released. The 403 system pushes the spacer 4〇6, the ball bearing 405, and the intermediate member 4〇4 toward the base 4〇7. At this time, the intermediate member _ is driven by the pulling of the piston 5 to rotate and simultaneously causes the piston 5 and the base 407. The distance between them increases, whereby the space which is increased by the wear of the inner and outer brake shoes 61, 62 of the brake element 6 can be compensated. φ change ^, for the operation of the whole brake caliper c, the brake master cylinder p can not supplement the hydraulic oil W of the brake caliper C, and the volume and volume of the oil cup 1Γ of the brake master cylinder p can be smaller than The conventional oil cup U in Fig. 2 makes it easier for the oil cup 11 to be concealed in one of the provided bodies (not shown) or other structures. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and the present invention can be modified and retouched without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application attached. 201031837 [Simple description of the drawings] Fig. 1 is a schematic view showing a conventional hydraulic system; the second chart is not based on the conventional hydraulic brake system of Fig. 1; and ''a third figure shows a brake of the present invention Schematic diagram of the caliper.
