Air Brake Spring Tools

Air brakes are mostly found in heavy duty trucks. The air brakes make it possible for the truck driver to apply emergency brakes because they have powerful springs which are held back by air pressure. Removal of the air pressure results in the air brakes becoming fully functional. The barking power of spring brakes depends on how well the brake springs are adjusted. There are various air brake spring tools for this task.

S-Cam Air Brake Spring Tool

The S-cam air brake spring tool is used to safely replace the brake shoes of tractors and trailers. The user hooks the retaining spring loop and presses down against the axle. Lever action against the axle simplifies the task with less effort. This tool is also used to install the S-cam return spring on air brake systems. Using the S-cam tool eliminates the need for unsafe methods such as grip wrenches, pry bars or screw drivers.

Air Brake Anchor Spring Pliers

Air brake spring pliers are used to install air brake springs. They consist of two plier arms, a pivot lug that usually projects from each of the plier arm and a pivot pin which allows for effective pivotal movement. They also have a spring with a slot that extends at the end of each plier arm. The pliers parts are arranged in such a way that they can accommodate air brake springs of all types.

Hold-Down Spring and Return Spring Tool

Hold-down brake springs are easily installed manually as they are lighter than return air brake springs. A hold-down spring tool looks like a hybrid of a nut driver and a screw driver. The spring retaining washer is gripped and rotated by a specially shaped end of the hold-down spring tool. Most return air brake springs have sockets and hooks which release and install the ends of air brake springs. Some of the return air brake springs look like pliers.
