Key Features & Benefits

This thing basically stores compressed air. Think of it like a spare tire for your air brake system. The air compressor builds up pressure and sends it into this reservoir, and then that stored air is used to operate your brakes, shift gears if you’ve got an automatic transmission that uses air, and sometimes even things like your horn. It's a holding tank, really. Most systems have multiple reservoirs, but this 30 – liter is a pretty common size. It’s a key piece of your air brake system. The compressor doesn't always pump out air exactly when you need it—like when you slam on the brakes. The reservoir provides that instant reserve of pressurized air so you get consistent, strong braking power. It also helps smooth out the pressure fluctuations from the compressor, keeping things running evenly.

Symptoms, Risks & Replacements

Without a functioning air reservoir, your brakes become unreliable, and that’s a serious safety concern. You’ll notice if it's failing because your brakes might feel spongy, slow to engage, or you might hear the air compressor running constantly trying to keep up. A leaking reservoir means you're losing air pressure, and that impacts everything the air system controls. You can find these pretty easily, we have a good selection at Fixparts Online, and replacing a failing reservoir is preventative maintenance that can save you a lot of trouble down the road. It’s not something you want to gamble with.
