Wabco 4613159372 Silencer Kit

Description

This Wabco Silencer Kit (MPN: 4613159372) is a critical component for air brake systems, specifically designed for use with air valves. It functions to reduce noise and maintain optimal air pressure within the braking circuit. This kit is a repair solution to restore the performance of existing air brake systems. Measuring 75 x 65 x 95 mm, this kit meets OE specification and ensures reliable and efficient braking performance.

Key Features & Benefits

Basically, this kit replaces the exhaust valve on your treadle valve – that’s the part you push with your foot to apply the spring brakes. It’s designed to quickly release air when you lift your foot, and then muffle that exhaust sound. The kit usually includes a new valve, o – rings, and sometimes a small filter. It's a pretty straightforward replacement, honestly. Think of it as part of your safety net. When you hit the brakes, or want to engage the spring brakes, air needs to be released from the system. This kit controls how that air is released – quickly, but quietly. It’s specifically for the exhaust side of the treadle valve, so it doesn’t affect the actual braking power, just the sound associated with applying the emergency or parking brakes.

Symptoms, Risks & Replacements

You’ll notice if this thing goes bad. It’ll start making a really loud hiss or “whoosh” sound every time you touch the pedal. It’s annoying, for sure, but it’s also a sign that air is escaping where it shouldn't, and that could eventually lead to a loss of efficiency or, at worst, a failure in the system. It acts like a shield, keeping the noise down and making sure the air release is clean and controlled. You can find these kits pretty easily; Fixparts Online has a good selection. It's a relatively inexpensive part to replace and can save you a headache down the road.
