What should I expect during installation and maintenance?

Installation is typically simple for anyone familiar with ATV brake systems: remove the old master cylinder, transfer any brackets or sensors, mount the new unit, and bleed the brakes to remove air. Routine inspection of brake lines and fluid will keep the system functioning reliably after replacement.

• Mounts using existing hardware and original brake line connections.

• Use manufacturer-recommended brake fluid and check for leaks after first ride.

Will this part work with my existing brake components?

In most cases the OLIFANT master cylinder integrates with stock calipers, hoses and reservoir setups as it mirrors OEM interface points. If your ATV has non-stock brake upgrades, verify thread sizes and port fittings to ensure compatibility.

• Compatible with original-style brake lines and caliper assemblies for listed models.
• Confirm brake fluid compatibility and reservoir fit prior to final assembly.
• Adapters or custom lines may be required for aftermarket upgrades.
