ABSTRACT:
A method for installing and removing brake springs and brake shoes in a vehicle involves the following steps: removing a wheel from the vehicle and removing a brake hub from the vehicle (If the brake assembly is situated on an apparatus other than a vehicle, the step of removing the wheel is not included.), placing an end of an elongated lever having a bifurcated gripping member on a lip of a lower brake shoe, rotating the elongated lever clockwise causing the lower brake shoe to rotate outwardly from a contracted position to an extended position, removing a lower cam roller, placing the end of the elongated lever having the bifurcated gripping member on a lip of an upper brake shoe, rotating the elongated lever counterclockwise causing the upper brake shoe to rotate outwardly from a contracted position to an extended position, removing an upper cam roller, placing another end of the elongated lever having a bifurcated grasping member around a brake spring shaft of a brake spring, placing an upper edge of a brake cam into a cam lifting and restraining notch on the elongated lever, using a point of contact of the upper edge of the brake cam and the cam lifting and restraining notch as a fulcrum and rotating the elongated lever clockwise, removing a brake spring restraining hook on the brake spring from a brake spring restraining member and removing the lower brake shoe and the upper brake shoe are the remaining steps. Assembly is accomplished by reversing the above steps.
