A brake pad structure of a hydraulic brake (10) includes a back plate (21,22), a friction member (40) and a heat dissipation device. The back plate has a first heat transfer coefficient. The heat dissipation device includes a connecting portion (31) and a heat dissipation portion (32). The connecting portion (31) is disposed between the back plate (21,22) and the friction member (40). The heat dissipation portion is protrusive outside the back plate and the friction member. The heat dissipation device has a second heat transfer coefficient greater than the first heat transfer coefficient. Whereby, heat of the friction member (40) can be transferred to the air via the heat dissipation device, and thus the friction member will not be superheated and less heat can be transferred to the hydraulic fluid inside an oil pressure cylinder, such that failure of brake can be prevented. |
