Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, a rear brake disc with good heat dissipation performance in the present embodiment includes a friction portion 1, and a connecting portion 2 having a bottom penetrating through an outer side of the friction portion 1 is fixedly connected to an inner cavity of the friction portion 1; the friction part 1 is the friction part of a caliper and a rear brake disc when an automobile brakes, and the connecting part 2 is the connecting part of the rear brake disc and an automobile shaft; the bottom of the connecting part 2 is communicated with a plurality of bolt holes 3, the bottom of the connecting part 2 is communicated with a central hole 4, and the side surface of the friction part 1 is provided with a heat dissipation groove 5 extending along the circumferential direction of the friction part 1; the surface area of the rear brake disc is greatly increased due to the arrangement of the heat dissipation grooves 5, and the natural heat dissipation capacity is better. The inner cavity of the friction part 1 is fixedly connected with a plurality of drainage plates 8 positioned in the inner cavity of the radiating groove 5; a plurality of drainage plates 8 are annular equidistance and distribute, and drainage plate 8 is the slope setting. The top of the friction part 1 is provided with a plurality of first heat dissipation holes 6 communicated with the heat dissipation groove 5, and the bottom of the friction part 1 is provided with a plurality of second heat dissipation holes 7 communicated with the heat dissipation groove 5; the arrangement of the first heat dissipation hole 6 and the second heat dissipation hole 7 further improves the heat dissipation capability.
