10 Best Trailer Brake Controllers: Proportional & Time-Delayed
If you own a trailer then you probably know how difficult it is to maneuver on the road, especially when applying the brakes.
This is because your vehicle brakes need to press harder because of the additional weight of the trailer added to that of the towing vehicle. Therefore, it can be dangerous especially if your trailer exceeds 1000 lbs of weight.
In order to solve this problem, you can install a trailer brake controller. In short, the trailer brake controller is a small piece of electronics that connects to your brake paddle switch and trailer connector.
What this device will do is offer a smoother braking response to your trailer on any stop you make by automatically controlling the trailer brakes.
It has a sensing technology inside that calculates in real time the towing vehicles speed and rate of deceleration. It then automatically applies the brake for you for a smoother braking experience.

Types of Trailer Brake Controller
#1. Proportional
The proportional trailer brake controller is the most popular type of controller on the market.
When the trailer is in motion and at a certain speed, the proportional trailer brake controller will automatically make adjustments such that it delivers the right amount of force on the brake pads of the trailer. This type of trailer brake controller has a fairly complex internal design that is more advanced when compared to a time-delayed model.
Indeed, it has a small CPU pretty much like a computer that constantly makes calculations about the speed it is moving and how much force needs to be applied to the trailer brakes.
Advantages:
- Since it makes real-time calculations, braking is much faster and almost real-time
- The proportional trailer brake controller is known for its smooth and linear braking
Disadvantages:
- A little bit more expensive than in time delayed brake controller
- The installation is a little bit more difficult since it has more wires and a more complex internal design
If you don’t want to be bothered with complex adjustments, the proportional trailer brake controller is an easy to use controller type. Simply install it and it will do all the braking automatically for you.
Additionally, if you value comfort when braking, this is the type of trailer brake controller to go with as the braking is incredibly smooth.
#2. Time-delayed
The time-delayed trailer brake controller is the oldest type of controller on the market. This type of controller sends a signal to your trailer brake pads based on the settings and adjustments that you tell it to do.
Unlike the proportional trailer brake controller that makes those calculations automatically, you will have to tell the time-delayed trailer brake controller the amount of force it needs to apply at the brakes.
Therefore, this type of brake controller can be imagined to be a “manual” trailer brake controller when compared to the proportional type.
Advantages:
- Cheaper than the proportional trailer brake controller
- Due to a simpler design, it is more easy to install
- It has more adjustments and offers more customization options
Disadvantages:
- Since the braking is more severe, it causes more wear-and-tear to the trailer brake pads
For those on a small budget or like to tweak the braking system to the way they like, the time-delayed trailer brake controller is an excellent choice. It offers tons of customization, is easy to install and very affordable.
How to Buy a Trailer Brake Controller
#1. Electric or Hydraulic
There are basically 2 types of trailer brakes on the market. The electric and hydraulic trailer brake. The electric trailer brakes are the most common type of brake that you will find an is literally an industry standard in trailers.
This is because this type of brake is cheaper to make as well as has a good response time. On the other hand, the hydraulic brake is mostly found in vehicles like cars and is a more modern and performing type of brake. However, it is also more expensive.
When choosing between the electric and hydraulic brake, noting that it makes little difference to the trailer brake controller as this controller is able to control both types of brakes with equal ease. Therefore, even if your trailer is equipped with a hydraulic brake, you will be able to find a good trailer brake controller to work with it.
#2. Voltage
When it comes to voltage, the trailer brake controller works with either a 12 V power supply or a 24 V. Some traders are able to output only 12 V DC while others will provide you a range of voltages from 12 V to 24 V. If you use the wrong type of voltage on your trailer brake controller, obviously it will damage the device so you need to ensure the right type of voltage first.
#3. Number of Axles
Basically, the number of axles in a trailer brake controller will dictate how many wheels it can control. The more axles it can connect to; the more wheels it will be able to control. In general, trailer brake controllers are able to control 1 - 2 axles, 1 - 3 axles or 1 - 4 axles for controlling up to 8 wheels at a time.
You will need to choose the right type of axle based on your trailer type. If your trailer has 4 axles, then going with a 2 axle trailer brake controller is not a good idea as it will make it underperform.
#4. Display
The display is where you get a visual idea about what is going on in the wheels of your trailer. Most high-quality trailer brake controllers will display a diagnostic of the battery, output current, and brake pad force applied in real-time.
In general, led monitors are very reliable, durable and long-lasting. They are also easy to see at night as well as during the day with no glare.
Moreover, the amount of details displayed in the display of your trailer brake controller is another important factor to consider. Evidently, the more details you get the better since this will provide you with more information.
#5. Setting options
The setting option will allow you to make different adjustments to your trailer brake controller. If you need to control the force exerted on the brake pads of your trailer with the trailer brake controller, then you need to go with a model that offers you this type of setting. It is usually called a “boost feature”.
Additionally, you may want to switch between a hydraulic and electric trailer brake mode on the fly as these offer you two different types of braking experiences. Some models of trailer brake controllers allow you to do that with the push of a button in all safety.
#6. Easy to install
You do not want a trailer brake controller that is overly complex to install.
Basically, all you will have to do is splice the wires of the trailer brake controller and connect it to the trailer connector as well as to the brake paddle switch for it to have complete control over your trailer brakes.
#7. Size
The size of the trailer brake controller is especially important when you want to install it in your dashboard. You do not want it to be too big if you have a small dashboard, for example.
Additionally, the controller needs to be installed in a strategic position such that it is easy to reach and make adjustments to when necessary.
#8. Warranty
For peace of mind, you want a trailer brake controller that comes with a warranty that is at least 1 year.
This device is almost impossible for the average person to repair so you may want to factor in that extra level of reassurance with a warranty period from the manufacturer.
