The Yato Brake Retainer Spring Tool 170 mm is a hand tool designed to help remove and install the return/retainer springs in drum‑brake systems. It measures roughly 170 mm in length and is made of carbon steel with a PVC handle, which provides durability and a comfortable grip. Because it’s purpose‑built for drum‑brake springs, it helps make brake‑shoe‑replacement jobs cleaner, safer, and faster than trying to force springs with generic pliers. Its relatively short length makes it handy for accessing springs in tight brake‑drum assemblies. For anyone working on vehicles with drum brakes — especially older cars — this tool is a practical addition to the toolbox.
