Triumilynn Brake Master Cylinder for Honda ATVs — 14mm Front Right, Black-Anodized Alloy Direct-Fit

Triumilynn's 14mm front right brake master cylinder is a direct-fit replacement for many Honda ATVs that restores firm lever feel and reliable hydraulic stopping power.

If your ATV lever feels spongy, pulls to the grip, or loses pressure after heavy trail use, a worn or leaking master cylinder piston and seals are often the cause. This Triumilynn unit is precision-machined from black-anodized alloy with a 14mm piston bore and the correct 10x1.25mm banjo bolt provision, engineered to resist mud, salt spray and water so you get consistent braking across muddy trails, steep descents and water crossings.

Will this master cylinder fit my Honda Rancher or Foreman?

Yes — the Triumilynn master cylinder is designed as a direct bolt-on for many Honda models. It matches the stock 7/8" (22mm) front right perch arrangement and replaces OEM numbers commonly used across Rancher, Foreman, Recon and other FourTrax/TRX lines.

• Compatible models: Rancher 350/400/420, Foreman 400/450/500, Recon 250/650/680, Rubicon 500, FourTrax 300/400, TRX series and selected GL/CB/CX variants.
• OEM replacement numbers: 2FM-FTVMC001, 45510-HM3-901, 45510-HM3-306, 45510-HM3-305.
• Mounts to standard 7/8" / 22mm front right perch setups.

How does this restore brake lever feeling?

The upgraded piston and fresh seals eliminate internal leaks and restore hydraulic pressure so the lever no longer pulls to the handlebar. That firm, predictable response improves rider confidence on technical terrain without changing bleed procedures or brake lines.

• 14mm (0.55") piston bore for OEM-equivalent pressure characteristics.
• New seals and machined bore to stop fluid bypass and soft feel.
• Works with existing calipers and lines — no system modifications required.

What does installation involve and what tools are included?

Installation is straightforward and intended for quick field or garage use: the unit clamps onto the existing perch and uses common brake fittings. Triumilynn includes a dedicated wrench and L-shaped screwdriver so you can tighten the banjo bolt and secure the master cylinder without searching for extra tools.

• Bolt-on fit for right-side 7/8" (22mm) front perch — typical install time is minutes.
• Includes a wrench tool and L-shaped screwdriver for fast, correct tightening.
• 10x1.25mm banjo bolt specification matches common brake hose fittings.

How durable is the construction for off-road use?

The body is black-anodized alloy that resists corrosion and mechanical wear from trail conditions. Built to withstand mud, salt spray and water exposure, it maintains function where cheaper cast or painted parts may deteriorate.

• Black anodized alloy housing for corrosion resistance and reduced wear.
• Precision machining for tight seal tolerances and long-lasting performance.
• Designed for frequent exposure to wet, muddy, and salty environments.

Who is this for: Riders who need a reliable, quick replacement master cylinder for Honda ATVs — especially owners of Rancher, Foreman, Recon, Rubicon and FourTrax models experiencing soft lever feel or internal brake leaks. It's also a practical upgrade for off-road enthusiasts who want a durable, corrosion-resistant unit that installs with basic tools and restores consistent stopping power without altering the existing hydraulic system.
