摘要：A tool and a method for installing and removing a spring for brake shoes on a large vehicle. A shaft has a handle angularly connected to a first end. A spike is mounted on the shaft, the spike being spaced apart and approximately parallel to the shaft. Preferably the shaft has two oppositely formed bends between the spike and the second end of the shaft. The spike engages the arcuate end of the spring and the shaft is leveraged to expand the spring to permit engagement and disengagement of the end of the spring with the brake shoe.
