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.
