OTC 50810 Spring Brake Tool

The OTC 50810 brake spring tool is designed to remove and install return springs on drum brakes, especially medium- and heavy-duty truck applications.
Here's what it does:
Safely removes brake shoe return springs on air brake systems (like those found on Class 7 and 8 trucks).
Installs the springs back without prying or excessive force, reducing the risk of injury or damage.
Works specifically with S-cam drum brakes, which are common in heavy trucks and trailers.
Why it's useful:
The return springs on S-cam brakes are under a lot of tension and can be dangerous to handle without the right tool.
This tool gives you mechanical leverage and control, allowing you to compress or extend the spring in a safe and controlled way.
Think of it as a heavy-duty version of the drum brake spring tools used on smaller vehicles — but made to handle the force and durability requirements of commercial trucks.
