The world of trailer braking is complex, with many technical terms and concepts that can be confusing to those who are new to the industry. One term that is often misunderstood is “gain” on a trailer brake. In this article, we will delve into the world of trailer braking and explore what gain on a trailer brake means, why it’s important, and how it affects the overall performance of your trailer braking system.
When it comes to trailer braking, gain refers to the rate at which the brake pressure increases as the brake pedal is pressed. In other words, gain is the amount of pressure that is applied to the brake pads or shoes as the brake pedal is pressed. The gain of a trailer brake is measured in pounds per second (psi) and is typically expressed as a percentage of the maximum brake pressure.
The Importance of Gain on a Trailer Brake
Gain is a critical component of a trailer braking system, as it plays a significant role in determining the overall performance of the system. When the gain is too low, the brakes may not be able to slow the trailer down quickly enough, which can lead to a loss of control and potentially serious accidents. On the other hand, when the gain is too high, the brakes may overheat and wear out prematurely, leading to costly repairs and downtime.
Why is Gain Important?
There are several reasons why gain is important on a trailer brake:
- It affects the stopping distance: The gain of a trailer brake determines how quickly the trailer can be brought to a stop. A higher gain means a shorter stopping distance, while a lower gain means a longer stopping distance.
- It affects the brake wear: The gain of a trailer brake also affects the wear on the brake pads or shoes. A higher gain means more wear on the brakes, while a lower gain means less wear.
- It affects the brake temperature: The gain of a trailer brake also affects the temperature of the brakes. A higher gain means higher brake temperatures, which can lead to overheating and premature wear.
How to Measure Gain on a Trailer Brake
Measuring the gain of a trailer brake is a complex process that requires specialized equipment and expertise. There are several methods that can be used to measure gain, including:
Brake Pressure Testing
Brake pressure testing involves attaching a pressure gauge to the brake master cylinder and measuring the pressure as the brake pedal is pressed. This method is commonly used to measure the gain of a trailer brake, as it provides a direct measurement of the pressure applied to the brake pads or shoes.
Advantages and Disadvantages
Advantages:
- Provides a direct measurement of the pressure applied to the brake pads or shoes.
- Can be used to measure the gain of a trailer brake at different pedal positions.
Disadvantages:
- Requires specialized equipment and expertise.
- Can be time-consuming and labor-intensive.
Brake Pedal Position Testing
Brake pedal position testing involves measuring the position of the brake pedal as the brake pedal is pressed. This method is commonly used to measure the gain of a trailer brake, as it provides a indirect measurement of the pressure applied to the brake pads or shoes.

Advantages and Disadvantages
Advantages:
- Does not require specialized equipment and expertise.
- Can be used to measure the gain of a trailer brake at different pedal positions.
Disadvantages:
- Provides an indirect measurement of the pressure applied to the brake pads or shoes.
- Can be affected by factors such as brake pedal travel and brake master cylinder design.
How to Adjust Gain on a Trailer Brake
Adjusting the gain of a trailer brake is a complex process that requires specialized equipment and expertise. There are several methods that can be used to adjust gain, including:
Brake Master Cylinder Adjustment
Brake master cylinder adjustment involves adjusting the brake master cylinder to change the gain of the trailer brake. This method is commonly used to adjust the gain of a trailer brake, as it provides a direct measurement of the pressure applied to the brake pads or shoes.
Advantages and Disadvantages
Advantages:
- Provides a direct measurement of the pressure applied to the brake pads or shoes.
- Can be used to adjust the gain of a trailer brake at different pedal positions.
Disadvantages:
- Requires specialized equipment and expertise.
- Can be time-consuming and labor-intensive.
Brake Pedal Adjustment
Brake pedal adjustment involves adjusting the brake pedal to change the gain of the trailer brake. This method is commonly used to adjust the gain of a trailer brake, as it provides a indirect measurement of the pressure applied to the brake pads or shoes.
Advantages and Disadvantages
