Key Features & Benefits

This lever basically translates what you do in the cab – pulling or pushing it – into air pressure sent to the trailer’s brakes. It’s a mechanical connection that opens and closes valves in the air system. It controls how much air goes to the brake chambers on the trailer axles. It has settings for service application – normal braking – and emergency/spring application, which locks the trailer brakes on if there’s a loss of air pressure. Some levers also have a parking brake function within that system. Think of it as the central control for your trailer’s braking. It’s the link between you and safely slowing or stopping whatever you're hauling. It works with the air lines, the compressor, and the brake chambers themselves. It doesn't do the braking, it tells the brakes to work. It's usually mounted inside the cab, within easy reach of the driver.

Symptoms, Risks & Replacements

Well, without a working lever, you have limited or no control over your trailer's brakes. That's a pretty big deal, obviously. You’ll notice if this thing goes bad because the trailer might not slow down as much as it should, or the parking brake might not hold. It’s a safety component, plain and simple. It acts like a shield between you and a potentially dangerous situation if your trailer gets out of control. It's one of those parts you really don't want to skimp on. If you're looking for a replacement, you can find a good selection, including these levers, over at Fixparts Online, but I always recommend checking your vehicle's specific requirements to make sure you get the right one.
