Wabco 4757106284 Piston

Description

This Piston is a critical component within air brake systems, specifically air valves. It functions to convert motion or force into reciprocal motion, enabling the operation of the air brake system. This piston is manufactured by Wabco with MPN 4757106284 and measures 90 x 27 x 89 mm. This OE specification piston delivers reliable performance and durability, contributing to the overall safety and efficiency of the braking system.

Key Features & Benefits

This little guy’s job is pretty straightforward. It moves back and forth inside a cylinder – think of it like a pump. That movement creates pressure, and that pressure is what actually does the work in your air brake system. It controls the flow of compressed air to the brake chambers, telling those brakes when to apply and release. It's really the heart of how air pressure gets turned into stopping power. It lives inside an air valve – usually a control valve or a relay valve. When you hit the brake pedal, or when the engine builds up air pressure, that signal goes to the valve, and the piston inside the valve moves. That movement allows air to flow to the brake chambers at the wheels. It’s a key part of the whole air brake network, helping everything work in sequence.

Symptoms, Risks & Replacements

Honestly, it's crucial. If this piston fails, or gets stuck, you could have a lot of problems. You might lose braking power – obviously not good. Or, it could cause the brakes to drag, causing overheating and wear. You’ll notice if one goes bad – usually through spongy brake feel, slow response, or even the brakes locking up. They're surprisingly durable, but they do wear out over time, especially with a lot of use and exposure to road grime. We carry a good range of these, and you can often find the exact one you need at Fixparts Online – they're a good source for quality air brake components. Getting the right piston is important for safety and keeping your vehicle reliably stopping when you need it to.
