A hand tool used in installing brake shoes comprising: an elongated shaft having one end bent at right angles and having a uniform circular cross section of a first diameter; and a rod having a uniform circular cross section with a second and smaller diameter, the rod being parallel to and extending in the same direction as the bent end while being secured at one end to the shaft adjacent but spaced from the bent end. The rod, shaft and bent end are coplanar. The bent end and the rod are of like length.

Claims

1. A hand tool used in installing brake shoes by hooking a retaining pin over a hold down spring placed in a brake shoe and then depressing the retaining pin end of the spring for hook up of the retaining pin while holding the shoe firmly against the backing plate, said tool comprising:

an elongated shaft having one end bent at right angles to the body of the shaft and having a handle grip at the other end, said shaft having a uniform circular cross section with a first diameter, said one shaft end engaging the coil of said spring when the tool is in use; and

a rod having a uniform circular cross section with a second and smaller diameter, the rod being parallel to the bent end and secured at one end to the shaft at a position adjacent but spaced from the bent end, the rod extending in the same direction as the bent end and being of like length, the rod, shaft and bent end being coplanar, the rod depressing the retaining pin end of the spring when the tool is in use.

2. The tool of claim 1 wherein the first diameter is 3/8 inch, the second diameter is 5/16 inch, the separation between the rod and bent end is 1/2 inch, the shaft is 9 inches long and both bent end and rod extend outward from the shaft for the same overall length, including the diameter of the shaft, of 2-1/4 inches.
