Proportional Brake Controllers
Proportional brake controllers sense when your tow vehicle slows down or stops and matches the speed and strength of the brake for the trailer. This is really handy because it will adjust to any type of braking situation. If you needed to stop short, the proportional brake will ensure that your trailer will stop just as abruptly as your vehicle. These types of controllers can be adjusted based on the weight and your normal braking tendencies.
Time-Delayed Brake Controllers
Time-delayed brake controllers use a preset amount of braking power. You are able to set the intensity and application rate. This means that every time you brake, your trailer will be stopping or decelerating the exact same way each time. It is activated when you first tap the brake, but the brake will not employ until it reaches maximum power output, hence the name time-delayed brake. One thing to account for is that even if you were to buy a sync switch to help reduce the delay, you will always experience a delay in braking. It may take some experimenting to determine the correct setting for your tow vehicle and trailer, as several different factors can affect which setting you'll need, such as trailer load and size, and weather conditions.
