The calculated volume of this cable is 9.6.

Key Features & Benefits

This cable basically delivers the electrical signal and sometimes a compressed air signal to activate the spring brakes – those emergency brakes that kick in if you lose air pressure. It's how the system 'talks' to the brake chambers, telling them to apply the brakes when needed. It handles power and data, similar to a computer cable, but for braking. Think of it as a vital link in your safety system. It connects the Electronic Control Unit – the brain of your air brakes – to the individual brake modulators at each wheel. Without a functioning supply cable, that communication breaks down, and your automatic safety features can't do their job. It’s part of the EBS – Electronic Braking System – and handles signals that control things like ABS and traction control as well, if equipped.

Symptoms, Risks & Replacements

It’s hugely important because it's a direct line to your emergency brakes. If this cable fails, you might lose that automatic application of the spring brakes when you need them most – like if you have a major air leak. You’ll notice if this goes bad because you might get a warning light on your dash, or the brakes just won't respond as they should during a test. You can find a replacement pretty easily – places like Fixparts Online carry them – and it's something you really don’t want to put off fixing. It's like a shield for your safety, so keeping it in good shape is critical.
