OLIFANT Front Brake Master Cylinder for Honda Rancher 420 & Foreman 500 — Direct-Fit Replacement, OEM-Compatible

OLIFANT front brake master cylinder is a direct-fit replacement part designed to restore reliable front braking for Honda Rancher 420, Foreman 500, Foreman Rubicon 500 and Rincon 680 models from the mid‑2000s to early‑2010s.

This precision-made master cylinder replaces worn or damaged front brake hydraulics on a range of Honda ATVs. Engineered to match OE mounting points and fluid ports, the unit fits model years listed below and uses the same brake fluid connections and lever interface, making installation straightforward for experienced DIYers and mechanics alike.

Which Honda models and years is this master cylinder compatible with?

How does this master cylinder simplify installation and maintenance?

The component is produced to align with original mounting bolt locations, brake-line fittings, and lever geometry, which reduces modification during swap-outs. That alignment helps shorten install time and minimizes adjustments when bench-bleeding and connecting hoses.

• Direct-fit bolt pattern and fluid ports for listed Honda models
• OEM-compatible lever mount and pushrod length
• Works with standard DOT brake fluids used in the original systems
• Simplifies bleeding with common bleed-nipple placement

What functional benefits can I expect from replacing my old master cylinder?

Swapping in a new master cylinder restores consistent hydraulic pressure at the front calipers and reduces spongy lever feel caused by internal seal wear or corrosion. Reliable pressure improves brake modulation and overall stopping performance without changing pad or rotor components.

• Restores firm lever response and consistent pressure delivery
• Eliminates fluid leaks due to degraded seals or housings
• Helps maintain balanced front-to-rear braking behavior
• Prevents progressive failure that can lead to complete loss of front braking

What should I check before ordering and installing this part?

Confirm your ATV’s model code and year against the compatibility list and OE references to ensure a match. Also verify the brake hose end fittings and lever orientation on your machine to avoid surprises during installation.

• Compare your current master cylinder OE number to the listed references
• Inspect hose fittings and lever location for left/right fitment needs
• Gather basic tools: wrenches, bleed kit, DOT brake fluid, and safety gear
• Consider replacing worn hoses or pads at the same time for best results

Who is this for? Riders and technicians who own compatible Honda Rancher, Foreman, Foreman Rubicon or Rincon ATVs and need a reliable, OEM‑style front brake master cylinder replacement will find this OLIFANT unit suitable. It is aimed at DIY mechanics and professional shops seeking a direct-fit, serviceable component to restore front braking performance and stop fluid leaks without extensive modifications.
