Product Detail
xBrake Lines · PTFE Core · SUS304 Stainless Braid
Stainless Steel Braided Brake Lines
TTSPORT stainless steel braided brake lines replace aging rubber hoses with a low-expansion PTFE core, SUS304 stainless braid, and a protective PVC outer sheath. The result is a firmer pedal, more direct hydraulic response, and more consistent feel under repeated hard braking.
Why Upgrade to Braided Lines
Factory rubber brake hoses flex under pressure. That flex absorbs hydraulic force before it reaches the caliper, which translates to longer pedal travel and a softer, less predictable feel. Braided stainless lines constrain that expansion so more of your input goes straight to the pistons.
- Sharper initial bite and shorter pedal travel
- More consistent feel during repeated stops
- Better modulation when trail-braking or threshold braking
- Pairs well with upgraded pads, rotors, and big brake kits
Construction
SUS304 Stainless Braid
Tightly woven stainless steel braid wraps the PTFE core to limit radial expansion and protect against pressure-driven ballooning.
PVC Outer Sheath
Smooth PVC jacket shields the braid from road grime and reduces abrasion against suspension components, paint, and surrounding hardware.
Crimped Fittings
Machined fittings are crimped to the line for a sealed, leak-resistant connection at the caliper and chassis hard-line side.
Specifications

| Not Intended For | Silicone-based DOT 5 brake fluid unless a specific application is separately confirmed |
| Function | Reduces hose expansion, firms pedal feel |
| Sold As | Brake line — fitment varies by vehicle |
Length, fitting style, and routing vary by application. Always verify fitment for your specific vehicle and brake setup before ordering.
This product page describes stainless steel braided brake lines only. Calipers, rotors, pads, brackets, rotor hats, brake fluid, and installation hardware are not included unless separately specified on the final order.
Installation Notes
- Confirm line length, banjo or flare fitting type, and thread size against the OE hose before installation.
- Route the line so it follows the original path with no twisting, kinking, or stretching at full suspension travel and full steering lock.
- Use new copper crush washers on banjo fittings and torque to the caliper manufacturer's specification.
- Bleed the brake system thoroughly after installation and check for leaks before driving.
- Inspect periodically for chafe points where the line could contact suspension, steering, or bodywork.
Safety: Brake line installation must be performed by a qualified technician. Do not force a line into position or allow it to rub against moving components. Improper installation can cause brake failure.
Good Pairings
Braided lines are the hydraulic finishing touch for any brake upgrade. They work well alongside performance pads, slotted or drilled rotors, fresh high-temp brake fluid, and big brake kit installations where pedal feel matters most.
Frequently Asked Questions
Will braided lines actually firm up my pedal?
Yes. By limiting hose expansion, braided lines reduce the amount of pedal travel absorbed by the hose itself. The change is most noticeable on vehicles with original or aged rubber hoses.
Are these lines compatible with my brake fluid?
The PTFE inner core is compatible with standard glycol-based brake fluids including DOT 3, DOT 4, and DOT 5.1. They are not intended for use with silicone-based DOT 5 fluid.
Do I need to confirm fitment before ordering?
Yes. Line length, fitting type, thread size, and routing vary by vehicle and by brake setup. Verify the exact fitment for your application before purchase, especially if you are running a big brake kit or modified suspension.
Can I install these myself?
Brake work should be performed by a qualified technician. The system must be properly bled and leak-checked before the vehicle is driven. Improper installation can cause brake failure.
How long do braided brake lines last?
The PVC sheath protects the braid from road debris and abrasion, supporting long service life. Inspect the lines periodically for chafe, cuts, or contact with moving components and replace if any damage is found.
