Description

The Wabco 9507300070 Air Reservoir is a critical component within a vehicle's air brake system, responsible for storing compressed air used to actuate the brakes.

Constructed with a steel body, this device maintains consistent air pressure for reliable braking performance and adheres to OE specifications. It measures 279 x 278 x 571 mm and has a 30 L capacity, operating effectively between -50°C and +100°C, and supports a maximum operating pressure of 14.5 bar with 4 ports featuring M22 x 1.5 threads.

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.
