The invention discloses an air brake and an elimination method for balancing an air cylinder temperature effect. The air brake comprises a balanced air cylinder and a pressure stabilizing chamber, wherein the balanced air cylinder is used for completing an internal decompression process at a first pressure drop rate when the air brake is in the decompression braking process, and the pressure stabilizing chamber is used for completing the internal decompression process at a second pressure drop rate which is larger than the first pressure drop rate when the air brake is in the decompression braking process. According to the air brake and the elimination method for balancing the air cylinder temperature effect, due to the fact that the second pressure drop rate is larger than the first pressure drop rate, after the decompression braking process is finished, air pressure in the balanced air cylinder is greater than that in the pressure stabilizing chamber, therefore, pressure which slowly rises in the balanced air cylinder due to the temperature effect in the pressure maintaining process can flow to the pressure stabilizing chamber which has lower pressure inside through a first shrinkage cavity, and the stability of the pressure in the balanced air cylinder is improved. In addition, By means of the air brake and the elimination method for balancing the air cylinder temperature effect, the required cost is lower, and on the premise of low cost, a bad effect of the temperature effect on the balanced air cylinder is eliminated easily and effectively.
