Everything About RV Supplemental Brake Systems

Recreational Vehicle (RV) is a perfect means of transportation for long-distance trips and camping. However, the size and weight of an RV can make it difficult to brake efficiently, especially when traveling downhill or carrying a heavy load. This is where RV Supplemental Brake Systems come into play. In this article, we will cover everything about RV Supplemental Brake Systems, including their benefits, types, installation, and maintenance.

Benefits of RV Supplemental Brake Systems

When it comes to choosing an RV Supplemental Brake System, it is important to consider the type of brakes your RV has. While most systems use electric brakes, some larger RVs may require air brakes for efficient stopping power. Air brakes work differently from electric brakes in that they use compressed air to apply pressure to the brake pads or shoes. The air pressure is generated by an air compressor and stored in a tank. When the brake pedal is pressed, the air pressure is released, causing the brake pads or shoes to press against the RV’s brake drums or rotors, bringing the RV to a stop. If your RV has air brakes, it is important to select a Supplemental Brake System that is compatible with air brakes to ensure efficient and effective braking. 

Types of braking relays

When it comes to RV Supplemental Brake Systems, there are several types of relays that may be used to control the braking action. One common type is the Electrical Relay, which works as a switch to control the power supply to the braking system. Another type is the Solid State Relay, which uses semiconductors to switch on and off the power supply to the brakes. A Voltage Sensitive Relay is another type of relay that is used to automatically switch the power supply to the brakes on and off based on the RV’s electrical system voltage. 12v Relay is another type of relay that works by controlling the flow of electrical current between two or more circuits. Finally, a Starter Relay is used in conjunction with the RV’s starting system to control the power supply to the brakes during startup. Each of these relays plays a crucial role in ensuring that the RV’s braking system functions properly, and it is important to select the right type of relay for your specific RV and braking system.

Breakaway System

breakaway system is designed to apply the RV’s brakes automatically if the RV becomes detached from the towing vehicle.

The breakaway system consists of a switch, a cable, and a brake actuator. The switch is typically mounted on the RV’s hitch or tow bar, and the cable is attached to the towing vehicle. In the event of a breakaway, the cable pulls the switch, which activates the brake actuator, applying the RV’s brakes automatically.

The breakaways is a critical safety feature that can prevent accidents and damage to the RV and other vehicles in the event of a breakaway. It is required by law in most states and is a standard feature on most RV Supplemental Brake Systems.

When choosing an RV Supplemental Brake System, it is essential to ensure that the breakaway system is included and is functioning correctly. Regular testing of the breakaway system is also crucial to ensure that it is in good working order and can activate the brakes quickly in the event of a breakaway.

By incorporating a breakaway system into your RV Supplemental Brake System, you can have peace of mind knowing that your RV’s brakes will be automatically applied in the event of a breakaway, preventing potential accidents and damage.

Reduced Wear and Tear

One of the significant benefits of RV Supplemental Brake Systems is that they reduce wear and tear on the RV’s brakes. When driving an RV, the brakes are put under a lot of strain due to the vehicle’s weight and size. Over time, this strain can cause wear and tear on the brakes, leading to reduced braking efficiency and potential safety issues.

When you install an RV Supplemental Brake System, it helps to distribute the braking force between the RV’s brakes and the supplemental system, reducing the strain on the brakes. This helps to minimize wear and tear on the brakes, ensuring that they last longer and function correctly. As a result, you’ll save money on brake repairs and replacements in the long run.

Reducing wear and tear on the RV’s brakes also has other benefits. It helps to prevent brake overheating, which can cause brake fade, reducing the brakes’ stopping power. Additionally, it helps to improve the RV’s overall braking performance, making it safer to drive on the road. Overall, installing an RV Supplemental Brake System is an investment in your RV’s safety and longevity.

Types of RV Supplemental Brake Systems

RV Supplemental Brake Systems come in different types, each with its advantages and disadvantages. Here are the common types of RV Supplemental Brake Systems:

Portable Brake Systems

Portable Brake Systems are easy to install and remove, making them ideal for RVers who do not want a permanent installation. These systems have a remote controller that can be easily attached to the RV’s dashboard, allowing you to control the braking system from the driver’s seat.

Permanent Brake Systems

Permanent Brake Systems are installed directly into the RV’s braking system, making them more reliable and efficient. These systems require professional installation and are ideal for RVers who frequently travel long distances.

Hybrid Brake Systems

Hybrid Brake Systems combine the benefits of both Portable and Permanent Brake Systems. They are installed directly into the RV’s braking system and come with a remote controller, making them easy to operate.

Installation of RV Supplemental Brake Systems

The installation of RV Supplemental Brake Systems can be done by a professional or a skilled RV owner. However, it is important to follow the manufacturer’s instructions and ensure that the system is correctly installed to avoid accidents. Here are the steps to install an RV Supplemental Brake System:

Step 1: Choose a Suitable Location

Choose a suitable location for the brake controller, preferably near the driver’s seat. This location should be easily accessible and visible to the driver.

Step 2: Mount the Brake Controller

Mount the brake controller using the manufacturer’s instructions. Make sure that the controller is securely fastened to prevent it from moving during braking.

Step 3: Connect the Wiring

Connect the wiring according to the manufacturer’s instructions. Make sure that all connections are secure and properly insulated. The brake relays are an essential component of the system’s wiring and play a crucial role in ensuring that the brakes are applied at the right time. In a typical RV Supplemental Brake System, the brake controller sends a signal to the brake actuator when the brakes need to be applied. The brake actuator, in turn, sends a signal to the brake relays, which activate the brakes. The brake relays are responsible for ensuring that the correct amount of brake pressure is applied to the RV’s brakes, based on the RV’s weight and the braking force required.

It is important to ensure that the brake relays are working correctly and are installed correctly as part of the RV Supplemental Brake System. Faulty or incorrectly installed brake relays can lead to reduced braking efficiency and potential safety issues. Therefore, it is recommended to have a professional install the system and test it regularly to ensure that all components, including the brake relays, are working correctly.

Step 4: Install the Brake Actuator

Install the brake actuator into the RV’s braking system. This step requires professional installation to ensure that the actuator is correctly installed.

Step 5: Test the System

Test the system by engaging the brake controller and ensuring that the RV comes to a complete stop. If there are any issues, consult the manufacturer’s instructions or a professional.
