Wabco 9504040000 Air Reservoir

Description

The Wabco 9504040000 Air Reservoir is a critical component within air brake systems, primarily used in commercial vehicles to store compressed air. This stored air is then used to actuate the vehicle's brakes, ensuring reliable stopping power. This air reservoir features a robust steel body with dimensions of 236 x 206 x 192 mm and a 4 L capacity. Its design, built to OE specification, provides a calculated volume of 9.334 and operates efficiently within a temperature range of -50°C to +100°C, offering consistent performance and durability under demanding conditions. The reservoir utilizes M22 x 1.5 port threads and is rated for a maximum operating pressure of 12.5 bar.

Key Features & Benefits

Basically, it’s a tank that stores compressed air. The air compressor builds up pressure, and this reservoir holds that air ready to go. It also smooths out the airflow, kinda like a buffer. It doesn’t just hold air, it regulates it so you don't get surges or drops in pressure when you’re using your brakes or other air – powered systems. It often has a drain valve on the bottom to let out any moisture that builds up, which is important, we can talk about that later if you like. It’s a key part of your air brake system, obviously. It supplies the air needed to operate your brakes, but also things like your air horn, the parking brake, and sometimes even things like suspension systems on larger vehicles. It's the central holding place for the power that stops you, so it’s pretty crucial. It works with the compressor and the brake chamber to make everything function smoothly.

Symptoms, Risks & Replacements

Well, without it, your brakes just won't work reliably. You’ll notice if it starts to leak – you’ll probably hear a hissing sound, and your air compressor will run more often trying to keep up with the loss of pressure. A failing reservoir can lead to weak brakes, and that's a safety issue. Rust and corrosion are the biggest enemies here, so regular inspections are a good idea. If you need a replacement, you can find a good selection at places like Fixparts Online, and they usually have different sizes and capacities depending on your vehicle. It's a relatively straightforward part to replace, but safety is paramount with anything brake related, so if you’re not comfortable doing it yourself, definitely have a professional take a look.
