Key Features & Benefits

This cylinder basically converts air pressure into a linear pushing or pulling motion. Think of it like a really strong, air – powered arm. It extends and retracts – that’s the “telescopic” part – and it does that based on the amount of air pressure being sent to it. It's got multiple stages that slide inside each other, which gives it a longer stroke in a more compact space. It controls the application and release of the spring brakes on your trailer or truck. This part is a key piece of your air brake system, specifically dealing with the spring brakes. Those are the brakes that automatically engage if you lose air pressure – a big safety feature. The telescopic strut cylinder pushes against those spring brakes to hold them off when you do have air. When air pressure is released, the cylinder retracts and lets the springs do their job, applying the brakes. It’s commonly used in trailer applications, but you’ll find them on trucks too.

Symptoms, Risks & Replacements

It’s super important because it directly impacts your ability to control your vehicle. If this cylinder fails, your spring brakes could prematurely apply, or worse, not apply when they should. You’ll notice if it's failing, typically with difficulty controlling the trailer brakes or potentially the vehicle wanting to pull to one side. It's a critical safety component, so it’s something you don't want to put off repairing. You can find a replacement for most makes and models over at Fixparts Online, but getting it diagnosed properly first is always best.
