Wabco 8965108102 Cylindrical Compression Spring

Description

This Cylindrical Compression Spring is a vital component within air brake systems, specifically used in air valves to provide controlled compression and facilitate proper valve operation. Manufactured by Wabco with MPN 8965108102, this spring ensures reliable performance and longevity within braking applications. Measuring 101 x 121 x 52 mm, this OE specification component provides precise force and consistent responsiveness, contributing to enhanced brake system efficiency and safety.

Key Features & Benefits

This spring basically stores energy when something presses on it, and then releases that energy to push something else back. In this case, it’s used inside air valves, specifically to return parts to their normal position after they’ve been moved by air pressure. It’s a simple component, but it’s all about providing that constant, reliable return force. It handles a lot of repeated movement, compressing and expanding over and over. Within the air valve assembly, it acts like a shield against wear and tear. It ensures the valve closes properly and returns to a neutral state after the air pressure is released. It's part of the system that controls your brakes, working alongside other components like diaphragms and pistons. It’s not something you’d see directly, it lives inside the valve housing.

Symptoms, Risks & Replacements

It's surprisingly important. If this spring gets weak or breaks, the valve might not seal correctly. That could lead to air leaking from the system, and you’ll notice if your brakes feel spongy or take longer to engage. It's a small, inexpensive part, but a failing one can really affect your stopping power and, honestly, your safety. You can find these springs, and a ton of other air brake parts, over at Fixparts Online if you’re doing a DIY repair. It's just one of those things where replacing it proactively is a lot cheaper and safer than dealing with a brake failure.
