Ruizuma G-M806 Dual Piston Rear Disc Brake Caliper 60mm

Upgrade your rear braking system with the Ruizuma G-M806 Small Mantou Opposing Dual Piston Rear Disc Brake Caliper. Precision-engineered from aviation-grade aluminum alloy and finished with a hard anodized surface, this caliper delivers strong, linear, and smooth braking performance — perfect for commuters, beginners, and experienced riders alike.

🔧 CNC Forged Aluminum Alloy Construction

Crafted using aviation-grade aluminum alloy forging combined with CNC precision milling technology, this caliper offers superior rigidity and a lightweight profile compared to standard cast calipers:

• One-piece molded structure — resists deformation under sustained high-stress use
• Lightweight design — minimizes unsprung weight, enhancing handling and maneuverability
• Hard anodized surface — corrosion-resistant, scratch-resistant, and long-lasting color retention

📐 60mm Mounting Hole Spacing – Wide Compatibility

Standard 60mm locking point spacing makes this caliper universally compatible with a wide range of mainstream models:

• Designed for 220mm discs with a corresponding adapter bracket — straight bolt-on, no grinding or cutting needed
• Simple installation process suitable even for first-time modifiers

⚙️ Opposing Dual Piston Design – Linear & Confident Braking

The classic Small Mantou opposing double-piston layout distributes braking force evenly across the rotor for consistent, progressive stopping power:

• 34mm piston cylinder diameter — firm clamping force with smooth, linear engagement
• Ceramic metal brake pads included — enhanced friction coefficient, reduced wear, and quieter operation even in wet conditions
• Optimized return structure — prevents pad drag and uneven wear, extending brake pad service life

🛡️ Upgraded Sealing System – Leak-Free & Long-Lasting

• Temperature-resistant seals compatible with DOT3 and DOT4 brake fluid
• Reserved oil drain nozzle for easy air bleeding — beginner-friendly setup
• Resistant to heat fade during continuous braking — maintains stable feel during daily commutes, long touring runs, and spirited rides

Frequently Asked Questions

Q: What disc size is the Ruizuma G-M806 rear disc brake caliper compatible with?

A: The Ruizuma G-M806 caliper is designed for use with 220mm disc rotors. It features a standard 60mm mounting hole spacing and comes with a corresponding adapter bracket for a direct bolt-on fit — no cutting or grinding required.

Q: What brake fluid should I use with this caliper?

A: This caliper is compatible with both DOT3 and DOT4 brake fluid. We recommend using DOT4 for optimal performance. Always bleed all air from the brake line before use to ensure consistent braking feel and safety.

Q: Is there a break-in period required after installation?

A: Yes. After installing the caliper, a break-in period of approximately 50–100 kilometers is recommended. This allows the ceramic metal brake pads to properly seat against the disc rotor and reach peak braking efficiency.

Q: How do I verify I have a genuine Ruizuma G-M806 caliper?

A: Each authentic Ruizuma G-M806 caliper comes equipped with an RZMA laser anti-counterfeiting label. You can scan or verify this label to confirm the authenticity of your product and ensure you're receiving genuine quality components.
