OLIFANT Brake Master Cylinder Handle for Honda TRX 250 300

OLIFANT's 7/8" hydraulic brake master cylinder handle is a direct-fit replacement for many Honda TRX/Foreman/Rancher ATVs, offering a larger 14mm piston bore for stronger braking feel.

This heavy-duty brake master cylinder lever assembly is built for riders who need a dependable front-right hydraulic brake control that fits a wide range of Honda models, including TRX250, TRX300, TRX350, TRX400, TRX450, Foreman 400/450/500, Rancher 350/400/420, Recon 250, Sportrax and more. Manufactured to match common OEM mounting and hydraulic connections, it uses a 10x1.25mm banjo bolt and is listed under Honda part numbers such as 45510-HM3-901 and compatible variants.

Will this OLIFANT master cylinder fit my Honda ATV?

Compatibility covers many Honda four-wheelers that use a 7/8" handlebar master cylinder and a 14mm piston bore. Check your existing part number, banjo bolt thread size, and mounting layout to confirm a match before ordering.

• Designed for front/right side brake use on multiple TRX and FourTrax models
• Uses 10x1.25mm banjo bolt for standard hydraulic hose connection
• Cross-references: 45510-HM3-901, 45510-HM3-306, 45510-HM3-305 and 2FM-FTVMC001

How does the larger 14mm piston influence braking?

The bigger piston increases hydraulic displacement per lever stroke, producing firmer lever feedback and improved modulation compared with smaller-bore units. That gives more perceived braking power and finer control when you need progressive stopping on trails or work tasks.

• 14mm bore offers increased fluid displacement and firmer lever feel
• Helps with modulation for gradual or firm braking inputs
• Intended as an upgrade over smaller-piston assemblies for front brakes

What are the install details and what do I need to know?

Installation is straightforward for anyone familiar with ATV brake plumbing: swap the master cylinder, torque the banjo bolt to spec, and bleed the brake system. Use the correct banjo fitting and replacement crush washers; always bench-check for leaks and proper lever travel before riding.

• Mounts in place of OEM front/right master cylinders on compatible Hondas
• Banjo bolt thread size: 10x1.25mm — use new crush washers when reassembling
• Requires brake fluid bleed and lever travel adjustment after installation

What quality and part references should I expect?

OLIFANT manufactures this master cylinder to meet durable-use expectations with materials and machining suited to off-road duty. It is sold as an aftermarket upgrade or replacement and cross-references common Honda part numbers to help you identify fitment.

• Aftermarket upgrade part with reinforced components for regular use
• Listed part numbers: 45510-HM3-901, 45510-HM3-306, 45510-HM3-305
• Commonly recommended for front brake replacement on compatible models
