Hayes 100400C 100400B Air Actuated Electric Trailer Brake Controller Review

Let’s Talk About Hayes 100400C 100400B Air Actuated Electric Trailer Brake Controller

The Hayes 100400C 100400B Air Actuated Electric Trailer Brake Controller is a specialized piece of equipment designed to synchronize your tow vehicle’s air brake system with the electric brakes on your trailer. This controller from Hayes promises smooth and proportional braking, enhancing safety and control while towing. It’s designed to operate 2, 4, or 6 electric trailer brakes, making it versatile for a range of trailer sizes.

I’ve spent years wrestling with jerky trailer braking, a common issue when relying solely on the tow vehicle’s brakes. I needed a solution that would provide proportional braking, especially when hauling heavy loads of equipment to remote job sites. A solution that also would function reliably in all-weather.

The moment I unboxed the Hayes 100400C 100400B, I noticed the compact and rugged design. The textured black surface appeared durable. It seemed well-suited to withstand the rigors of constant use and exposure to the elements.

Compared to some cheaper, time-based brake controllers I’ve used, the Hayes system promised a far more sophisticated approach using the tow vehicle’s air brake pressure. I also considered a Tekonsha proportional controller. However, the integration with the existing air brake system in my work truck made the Hayes unit the logical choice.

My first impression was cautiously optimistic. The Hayes 100400C 100400B Air Actuated Electric Trailer Brake Controller looked like it could solve a major pain point, but the proof would be in the actual performance under load.

Real-World Testing: Putting Hayes 100400C 100400B Air Actuated Electric Trailer Brake Controller to the Test

First Use Experience

My initial testing involved hauling a 24-foot flatbed trailer loaded with construction equipment to a site about 50 miles away. The route included both highway driving and some challenging back roads with steep grades. This mimicked a typical work day.

The performance was immediately noticeable, even in light rain. The trailer brakes engaged smoothly and proportionally with the truck’s air brakes. No more jarring stops!

Installation took a bit of time, primarily due to the air line connections. However, once installed, the unit was intuitive, requiring minimal adjustment to achieve balanced braking.

Extended Use & Reliability

After several months of regular use, the Hayes 100400C 100400B Air Actuated Electric Trailer Brake Controller has proven its reliability. The braking remains consistent, even under heavy loads and in varying weather conditions.

I’ve noticed no significant wear and tear, and the textured black finish has held up well against dirt and grime. A quick wipe down with a damp cloth is usually all that’s needed for maintenance.

Compared to my previous time-based controller, the Hayes unit is a game-changer. The proportional braking gives far greater control. It instills confidence, especially when navigating tricky situations.
