Wabco 13302117 Pressure Spring

Description

The Wabco 13302117 Pressure Spring is a critical component within the brake drum assembly of mechanical brake systems. This spring provides consistent pressure to ensure optimal braking performance and reliable stopping power. As an OE specification component, this pressure spring is designed to match the fit and function of the original equipment, ensuring compatibility and ease of installation. It contributes to a safer and more efficient braking system by maintaining proper contact and force within the brake drum assembly.

Key Features & Benefits

This little spring’s job is pretty simple, but important. It provides consistent pressure on the brake shoes against the brake drum. It basically pushes the shoes out so they’re ready to grab when you hit the brake pedal. It works with other springs – tension and return springs – to make sure everything stays adjusted and responsive. Think of it like a little helper keeping everything tight and ready to go. It lives inside the brake drum assembly, nestled with those brake shoes. When you press the brake pedal, hydraulic pressure pushes the wheel cylinders, and those cylinders then push on the brake shoes. The pressure spring is already applying a base amount of force before that happens, making the whole process quicker and more effective. It ensures a solid initial contact between the shoes and the drum. It’s part of a system, so it works alongside all the other mechanical parts in there.

Symptoms, Risks & Replacements

If this spring gets weak or broken, you’ll start to notice a few things. You might get a soft or spongy brake pedal feel. It might take longer to stop, or you might need to press the pedal harder than usual. Basically, it affects your stopping power. It’s not something you want to ignore. A failing spring means less consistent braking performance. You can find these pretty easily – we stock them here, and places like Fixparts Online have them too. It’s a small part, but a vital one for keeping you safe on the road.
