Exact Fitment Guarantee
The AS3 Performance Braided Stainless Steel Brake Line Kit is a safety-critical hydraulic braking upgrade engineered to eliminate the spongy, vague brake lever feel caused by standard factory rubber brake hoses. Stock rubber brake lines expand elastically under hydraulic pressure, especially when brake fluid heats up during aggressive riding. This volumetric expansion wastes valuable hydraulic master cylinder pressure, resulting in excessive lever travel, reduced braking power, and inconsistent bite points into turns.
AS3 Performance brake lines eliminate line swell by utilizing an ultra-low friction PTFE (Teflon) internal core wrapped in a tight, high-density braid of 303/304 marine-grade stainless steel. This braided armor prevents any radial line expansion under extreme hydraulic pressures exceeding 4,000 PSI, delivering immediate 1:1 hydraulic force transfer from the master cylinder to the brake caliper pistons. The exterior is coated in a durable, UV-resistant PVC protective sleeve that prevents the stainless braid from scratching fork legs or chassis parts. The fittings are precision-swaged chrome-plated or stainless steel banjo ends designed with exact OEM routing angles.

Incorrect installation, loose banjos, or improper bleeding can result in total brake failure and serious injury. If you are not confident in hydraulic brake service, have this part installed by a qualified motorcycle technician.</p></div> Installation involves draining the existing brake fluid from the system. Unbolt the upper and lower banjo bolts holding the stock rubber line, catching residual fluid in a rag. Route the AS3 Performance braided line through the factory fork guard routing guides. Install the line using new copper crush washers on both sides of each banjo fitting (always use two new copper washers per banjo bolt). Torque banjo bolts to 18-20 Nm. Fill the master cylinder with fresh DOT 4 or DOT 5.1 brake fluid (never use DOT 5 silicone fluid). Bleed the brake system thoroughly using a vacuum bleeder or manual pump-and-hold method until all air bubbles are purged and the lever is rock-solid. Check for fluid leaks around all fittings before riding.
### Maintenance & Brake Fluid Flushing Maintenance involves inspecting the protective outer jacket for wear and flushing brake fluid annually.
Frequently Asked Questions
Q: Why does a braided brake line provide a firmer lever feel?
A: Unlike rubber hoses that balloon outwards under hydraulic pressure, stainless steel braided lines do not expand radially, ensuring that 100% of the master cylinder pressure is transmitted directly to clamping the brake pads against the rotor.
Q: Are new copper crush washers included with the brake line?
A: Yes. AS3 Performance includes new copper sealing washers to ensure an airtight, leak-free seal at the master cylinder and caliper banjo joints.
Q: What brake fluid should I use with AS3 Performance braided lines?
A: Use fresh, high-performance DOT 4 or DOT 5.1 glycol-based brake fluid from a sealed container. Never use DOT 5 silicone-based fluid, which is incompatible with standard off-road motorcycle braking seals.
Q: Can braided lines get damaged if routed incorrectly?
A: Yes. Always ensure the line is routed through factory fork guard guides and has sufficient slack through the entire suspension compression stroke to avoid pinching or stretching.
