V‑Twin Brake Lines

V‑Twin Motorcycle Brake Lines

That Keep Levers Sharp

GBrakes® V-Twin Brake Lines use braided stainless steel outer sheaths and PTFE (polytetrafluoroethylene) cores to eliminate line swell and lever vagueness. Every line is built to match your bike’s geometry for kink-free routing, cut to custom lengths, and pre-bled for instant installation. The result is tighter lever response, consistent pressure, and lifetime durability – no fade, no mush, no guesswork. Start configuring your custom V-Twin lines now.

Let your lever give out and the rest isn’t far behind. Stock rubber lines swell under heat and pressure, especially when you’re hauling a V-Twin around corners or dropping into canyon descents. GBrakes® builds V-Twin motorcycle brake lines with braided stainless steel outer sheaths and PTFE (Polytetrafluoroethylene) cores that maintain consistent feel and pressure, no matter how hot or heavy your ride gets. Each one is built to spec no one-size-fits-all. We cut lines to match your bike’s geometry and fork travel, whether you’re running extended front ends, raised bars, or lowered rear suspension. That means clean routing, no kinks, and zero clearance issues.

Inside, the PTFE core resists fluid absorption and expansion. Outside, the stainless steel braid keeps everything firm under pressure. You’ll notice the difference in lever feel immediately: tighter, more responsive, and consistent stop after stop. And it’s not just the guts. GBrakes®’ V-Twin motorcycle brake lines are available in multiple colors at no extra charge, include all necessary hardware, and come with a lifetime warranty. We even offer custom lengths for special builds or upgraded front ends. Whether you’re carving canyon roads or stacking highway miles, Our lines are a true system upgrade, delivering confidence, control, and durability for real-world V-Twin riding.

Vagueness in the lever? That’s line swell. Delayed bite after a downhill stop? That’s fluid heat soak and expansion. You need braking you can feel through your fingers, not braking that disappears mid-corner. If your current setup can’t keep pace with real V-Twin riding, it’s not you, it’s the hardware.

Gbrakes® Stainless Brake Lines: Built for the Weight, Heat, and Distance

Steel-Braided Construction

Wrapped in high-tensile stainless, our lines eliminate flex and expansion under braking load. You get precise, immediate lever response in all conditions, including heavy hauling, heat, and elevation shifts.

PTFE Core for Consistent Flow

The inner core is PTFE (Teflon) for zero fluid absorption, no sponginess, and no flow degradation over time. It stays consistent from mile 1 to mile 10,000.

Custom Lengths Available

From +2” to +12”, we build to match extended forks, ape hangers, and dropped rear ends. No excess slack. No tension at full fork travel. You get proper geometry and clean routing, every time.

Color Options at No Extra Charge

Choose from stealth black to high-contrast reds, clears, or braided raw, your build, your spec, no markup for looks. Hoses, fittings, and sheaths, fully customizable.

All Hardware Included

Every line ships with stainless banjo bolts, crush washers, clips, and routing hardware. No guessing, no sourcing extra parts. One box. One install. Done.

Sensor-Safe for ABS V-Twins

Running ABS? We spec fittings and routing to avoid interference and sensor feedback errors. Clean signal, clean performance.

Lifetime Warranty

If it leaks, fails, or cracks, we replace it. You ride hard. We back you harder.

Upgrade Feel, Control, and Trust

Sharper Lever Snap

No lag. No sponge. Get immediate engagement from the first pull — critical in stop-start traffic and steep grade riding.

Less Fade, More Confidence

Our lines maintain pressure even after sustained braking. That means shorter stops and more consistent feel — especially under load.

OEM-Fit Appearance

Custom-routed lines follow factory paths with a cleaner, tighter look. No hacks, no sloppy loops, no zip-tie jobs.

Built for the V-Twin Life

From Sturgis to Daytona, we’ve built brake lines for riders who run deep miles.

From the Black Hills to Beach Street, Gbrakes® stainless lines are trusted by riders who clock real miles. If you’re loaded down, pulling heat, and threading traffic after 600 miles in the saddle, your brakes feel better being locked in.

This is a system upgrade for riders who demand more from their levers, because they ride harder, longer, and smarter.

Built for the weight. Backed for the ride. Proven from Sturgis to Daytona.

Front, rear, full kits, braided steel, DOT-rated, and custom fit for your build. If you upgraded your bars, brakes, or just want better control, this is where to start.
Why Stock Brake Lines Fail on V-Twins
Once installed, these brake lines:
  • Fit cleanly across triple trees and through caliper mounts
  • Avoid bars, bags, and rear-wheel clearance issues, even under full lean
  • Plug straight into OEM masters and calipers, no adapters needed
  • Maintain leverage feel from near-new to nightmare conditions
These lines connect directly to OEM master cylinders and calipers using factory-spec fittings. No adapters, no hacks, and no rerouting. Every pull feels tight and responsive, not vague or inconsistent. This is brake hardware designed for the real shape and weight of your V-Twin, not a generic hose kit pretending it fits everything.
Ride Experience: What You’ll Notice

After installing these lines, here’s what becomes obvious, fast:

  • Sharper initial bite as soon as the lever is squeezed
  • Brake feel remains crisp, even after repeated hard stops
  • Fade resistance drastically improved on long descents or heavy pulls
  • Minimal line wear, thanks to steel protection and PTFE resilience

The outer braid resists abrasion and heat. The inner PTFE core keeps pressure tight and brake fluid moving cleanly. Together, they create a system that outperforms rubber on every metric: feel, durability, and control.

This isn’t just a new line, it’s a full transformation of how your brakes communicate with the road. You’ll feel more in control at slow speeds, in panic stops, and during long days in the saddle. And once you adjust to that new level of response, there’s no going back.

When to Upgrade Brake Lines
There’s no “standard” Harley. And there’s definitely no universal line setup that fits once you change anything up front. We account for:
  • You’ve added weight (bags, passenger, accessories)
  • You’re feeling soft or spongy brake response
  • You’re upgrading pads and rotors
  • You’ve slammed, cloned, or extended bars/forks
  • You’ve swapped masters or calipers
If you’ve modified your bike or noticed any change in brake feel, upgraded lines aren’t optional. They’re essential. They don’t just enhance your braking, they restore it to what it should’ve been in the first place.

V-Twin Brake System Integration

  • Follow OEM torque specs for fittings
  • Route hoses cleanly, avoid contact with hot parts or intake air flows
  • Check clearance at full lock and during compression
  • Perform a full bleed after install to eliminate air
  • Test ride from slow speeds up, verify feel and leverage
Once installed, take it slow. Your first few rides should confirm that brake feel is firm, lever travel is consistent, and response is immediate. That’s the baseline your V‑Twin should always ride with, and what a proper stainless line upgrade restores.
