Triumilynn Brake Master Cylinder for Honda Rancher & Foreman — Right-Side 14mm Bore, Black Anodized

If your front brake lever feels soft, pulls to the grip, or fluid is leaking, this precision-machined master cylinder rebuilds hydraulic performance without the cost or wait of factory service. Built from black anodized alloy with a 14mm piston bore, the unit resists corrosion and shedding mud or water, making it suited for off-road riding where exposure is common. It arrives as a right-side 7/8" (22mm) front perch assembly with the small tools needed for a straightforward bolt-on swap.

How does this master cylinder improve braking feel?

Worn seals or a damaged piston bore are common causes of spongy levers and diminished stopping power. Replacing the failed master cylinder restores hydraulic pressure, returning a firm, predictable lever stroke and more reliable modulation across varied terrain.

• 14mm piston bore for consistent hydraulic pressure
• Replaces worn or leaking original part numbers listed
• Tighter lever travel and improved brake bite after installation

Will this part fit my Honda ATV and how easy is installation?

The Triumilynn unit is built as a direct replacement for many Honda models—Rancher, Foreman, Recon, Rubicon, FourTrax and others—matching the stock 7/8" (22mm) front right perch. It clamps onto factory handlebar setups and uses standard 10x1.25mm banjo hardware for the brake line.

• Includes a wrench tool and L-shaped screwdriver for mounting
• Typical home-install takes minutes; no specialized shop equipment required

Who is this for? Riders and DIY mechanics who need a reliable, affordable replacement master cylinder for Honda ATVs—especially those who ride in muddy, wet, or steep conditions and want to avoid extended shop downtime. It’s aimed at owners of Rancher, Foreman, Recon, Rubicon, FourTrax and TRX series models that match the listed part numbers, and for anyone comfortable performing a basic brake hydraulic swap with the included tools. If you prefer a quick, bolt-on upgrade to restore lever firmness and braking consistency without waiting for dealership service, this Triumilynn master cylinder provides a direct, durable option.

Note: Always follow vehicle manufacturer guidelines for brake bleeding and torque specifications after installation. If you’re unfamiliar with brake system service, consult a professional mechanic.
