18 wheeler brake shoe tool systems

摘要

An 18 wheeler S-cam brake shoe tool system is a hand tool about 19½ inches in length having a U-shaped fork on one end and an S-offset on the other end. The length of the bar provides a user sufficient leverage as the bar is used to pry against a fulcrum point. The fork at the distal end of the tool and the S-offset at the proximate end are both integral with the bar. The U-shaped fork is used for positively gripping a brake spring while using the rod to pry against a fulcrum point to stretch the spring. The S-offset has a cylindrical end about ½ inch in diameter which inserts into an orifice on the frame of a brake shoe to positively grip the shoe, while using the rod to pry against the stationary S-cam to reposition the joined first and second brake shoes during removal or reinstallation.

主权项

1. An 18 wheeler S-cam brake shoe tool system comprising:
an S-cam brake shoe tool comprising;
a rod comprising;
a proximate end terminating in an S-offset;a distal end terminating in a U-shaped fork; anda lever shaft; wherein said S-offset is integral with said lever shaft and is located on said proximate end of said rod; wherein said U-shaped fork is integral with said distal end of said rod; wherein said lever shaft is located between said S-offset and said U-shaped fork; wherein said S-offset is useful for coupling to a brake shoe and providing leverage to spread said brake shoe(s) such that S-cam roller(s) are able to be installed by a user; wherein said U-shaped fork is useful for stretching a brake shoe(s) retaining spring such that a shoe retainer pin is able to be installed by said user while said brake shoe(s) are still coupled together by said brake shoe retaining spring; and wherein said S-cam brake shoe tool is useful to reduce installation time and increase safety of said user during a replacement of said brake shoe(s) with a new set of said brake shoe(s).
