There are different types of brake lines, each with its own characteristics, advantages, and maintenance requirements.
Types of Brake Lines
- Rubber Brake Lines: Most motorcycles come equipped with rubber (or synthetic rubber) brake lines from the factory. They are flexible and sufficiently durable for standard use. However, rubber lines can expand under the high pressure of hard braking, leading to a spongy feel in the brake lever or pedal.
- Stainless Steel Braided Brake Lines: These are rubber lines wrapped in a braided stainless steel mesh. The steel braiding significantly reduces expansion under pressure, resulting in a more consistent and firm brake feel. They are more durable than rubber lines and are resistant to abrasion and UV damage.
- Kevlar Brake Lines: Similar to stainless steel braided lines but with a Kevlar braid covering the rubber hose. Kevlar lines offer the flexibility and strength of steel braided lines but are lighter and less abrasive, which can be beneficial in certain applications.
Advantages of Upgraded Brake Lines
- Improved Brake Feel: Upgraded brake lines, particularly stainless steel or Kevlar braided lines, provide a firmer and more responsive brake lever or pedal feel due to reduced expansion under pressure.
- Increased Durability: Stainless steel and Kevlar brake lines are more resistant to wear, UV damage, and abrasion than standard rubber lines, making them a long-lasting upgrade.
- Enhanced Safety: The improved reliability and performance of upgraded brake lines can contribute to overall riding safety, especially under hard braking conditions or in emergency situations.
Maintenance and Inspection
- Regular Checks: Regardless of the type, brake lines should be regularly inspected for signs of wear, damage, or leaks. Look for any cracks, bulges, or leaks at the fittings and along the lines.
- Fluid Changes: When performing brake fluid changes (which should be done according to the manufacturer’s recommendations or at least every 1-2 years), it’s a good opportunity to inspect the brake lines and fittings for any issues.
- Correct Installation: If upgrading or replacing brake lines, ensure they are properly installed and routed without any kinks or undue stress points. The fittings should be securely tightened to prevent leaks.
- Compatibility: Ensure that any replacement or upgraded brake lines are compatible with your motorcycle’s make and model. Incorrectly sized or improperly installed brake lines can adversely affect braking performance and safety.
