Trailer Brake Lines: Thermoplastic, Steel, and Rubber

If you own a boat trailer, chances are you're familiar with the crucial role of brake lines. These essential components ensure the smooth operation of your trailer's braking system, providing safety and peace of mind while towing your valuable cargo. But have you ever considered the materials these brake lines are made of? From thermoplastic to steel and rubber, each material offers unique benefits and considerations tailored to specific trailer types and environments.

WHY DO BRAKE LINES MATTER?

Brake lines are the lifeline of your trailer's braking system. They transmit hydraulic pressure from the master cylinder to the drum or disc brakes, activating the brakes when needed. Choosing the right material for your brake lines is essential for optimal performance and longevity, especially considering the diverse conditions trailers often encounter.

THERMOPLASTIC BRAKE LINES: CORROSION-RESISTANT AND FLEXIBLE

Dexter thermoplastic brake lines are popular for their superior corrosion resistance, making them ideal for boat trailers exposed to saltwater environments. Unlike steel, thermoplastic doesn't rust, ensuring longevity and minimizing maintenance needs. Additionally, thermoplastic brake lines offer flexibility, allowing for easier installation and routing inside the tube frame of the boat trailer. This flexibility simplifies installation and enhances braking performance by maintaining fluid pressure over long distances. While thermoplastic brake lines may come at a slightly higher cost compared to steel, their durability and corrosion resistance make them a worthwhile investment for boat trailer owners seeking long-term reliability.

STEEL BRAKE LINES: INDUSTRY STANDARD FOR DURABILITY

Steel brake lines have long been the industry standard for durability and reliability. Their strength and corrosion resistance make them a great choice for various trailer types, including RVs, cargo trailers, and horse trailers. Whether rigid or malleable, steel brake lines offer the versatility needed for custom installations while ensuring high-quality performance. Steel brake lines are also cost-effective and readily available, with easy access to replacement parts for hassle-free maintenance. However, it's important to note that steel brake lines are susceptible to rust in
corrosive environments, such as saltwater or areas with high humidity. Proper care and maintenance are crucial to prolonging the lifespan of steel brake lines and preserving their effectiveness.

RUBBER BRAKE LINES: FLEXIBLE AND INSTALLATION-FRIENDLY

Rubber brake lines provide flexibility and ease of installation, making them popular for various trailer applications. With the ability to route inside the tube of a boat trailer frame without additional housing, rubber brake lines offer convenience and simplicity in setup. Rubber brake lines are generally more affordable than steel or thermoplastic options. However, they have a higher expansion rate over long lengths, slightly reducing braking quality.

CHOOSING THE RIGHT BRAKE LINE FOR YOUR TRAILER

When selecting brake lines for your trailer, consider the specific demands of your towing environment. Will your trailer be exposed to saltwater, humidity, or corrosive substances? For boat trailers, thermoplastic brake lines offer unmatched corrosion resistance and flexibility, ensuring reliable performance in harsh marine conditions. Meanwhile, steel brake lines are a durable and versatile option for RVs, cargo trailers, and horse trailers, though they require maintenance in corrosive environments. Rubber brake lines provide a cost-effective, installation-friendly alternative suitable for various trailer types where flexibility is paramount.
In conclusion, investing in high-quality brake lines is essential for ensuring the safety and reliability of your trailer's braking system. Whether you opt for thermoplastic, steel, or rubber brake lines, understanding the unique characteristics of each material will help you make an informed decision tailored to your trailer's needs.
