Key Features & Benefits

These little springs basically hold the brake shoes back from rubbing against the brake drum when you aren’t hitting the brakes. They pull the shoes inwards, away from the drum, so the drum can spin freely. They also help return the shoes to that resting position after you release the brake pedal. Each shoe usually has a couple of these. Think of it like this: your brake shoes are trying to press outwards against the drum to stop the car. The pull spring is working against that, constantly pulling them back – it's a balancing act. It’s a pretty simple part, but it's part of a system that needs everything working together to get smooth, reliable braking. It works alongside things like the hold – down springs and adjuster, all keeping everything in line.

Symptoms, Risks & Replacements

Honestly, if these springs get weak or break, you’ll notice if you’re paying attention. Your brakes might drag a bit – meaning the brakes stay partially engaged even when you aren't pressing the pedal. This will wear out your brake shoes and drums faster, and it can even cause the brakes to overheat. A dragging brake also reduces fuel economy. They’re inexpensive to replace, so it’s best to address it before it causes bigger problems. You can find them pretty easily, a place like Fixparts Online usually has a good selection. It's a small part, but a crucial one for safe, efficient stopping.
