Motuda CNC Four-Piston Disc Brake Caliper – Front & Rear Cycling Upgrade

Take your ride's stopping power to the next level with the Motuda CNC Four-Piston Disc Brake Caliper. Precision-machined from aircraft-grade 6-series aluminum alloy, this caliper delivers symmetrical, even braking force across front and rear wheels — making every ride more confident, controlled, and responsive. Whether you're hitting mountain trails, daily commuting, or riding in wet conditions, this caliper is built to perform.

Made in Mainland China.

Why Upgrade to a Four-Piston Caliper?

• Symmetrical Four-Piston Design: Four pistons apply uniform pressure to the brake disc, giving you faster braking response and strong, consistent stopping force with minimal handle effort — shortening braking distances significantly.
• High-Performance Sintered Brake Pads Included: Heat-resistant and water-slip-resistant sintered pads maintain stable braking performance during mountain riding, wet-weather commuting, and high-intensity cycling. Slow wear rate means longer pad life.
• Double-Layer Dust-Proof Oil Seals: Dual high-elasticity seals keep sediment and rainwater out of the oil circuit, ensuring long-lasting leak-proof performance and consistent brake feel without pressure attenuation over time.

Precision CNC Aluminum Alloy Construction

• 6-Series Aluminum Alloy Body: Higher hardness and superior corrosion resistance compared to standard alloys — resists deformation and cracking even during intense riding sessions.
• Full CNC Precision Milling: Smooth, burr-free internal oil circuits ensure effortless piston rebound and eliminate common issues like caliper locking or return jamming.
• Multi-Layer Hard Anodizing: Scratch-resistant shell that won't fade, preserving a like-new finish through seasons of outdoor cycling.

Easy Installation — No Frame Modification Needed

• Direct-fit replacement for the original front or rear wheel disc brake position — no grinding of frame or disc required.
• Novice-friendly installation: even first-time modifiers can complete setup with basic tools.
• Comes complete with fixing screws, gaskets, and brake pads — everything you need is in the box, ready to install on arrival.

Bold Multi-Color Styling

• Available in classic Black Gold, Matte Black, and eye-catching Gold anodized shells to match any bike build.
• Embossed MOTUDA brand logo with smooth, three-dimensional lines for a premium sporty look that far outclasses stock OEM calipers.
• Pairs perfectly with matching perforated floating disc sets for a full brake system upgrade in both function and appearance.

Strict Quality Control & Safe Packaging

• Every caliper undergoes high-pressure oil-pressure sealing inspection before leaving the factory, ensuring zero oil leakage or pressure-loss defects in every unit shipped.
• Individually packaged in a branded black color box with internal foam buffer protection for safe long-distance cross-border transportation.

Frequently Asked Questions

Q: Is the Motuda CNC four-piston caliper compatible with standard disc brake mounts?

A: Yes. The Motuda JK26 four-piston caliper is designed for direct replacement on standard front and rear disc brake positions on most bicycles. No frame grinding or disc modification is required, making it a straightforward upgrade for both beginners and experienced cyclists.

Q: What brake pads come included with the caliper?

A: The caliper ships with high-performance sintered brake pads that are heat-resistant and water-slip-resistant, making them well-suited for mountain riding, commuting, and wet-weather cycling. The complete package also includes fixing screws and gaskets so you can install immediately.

Q: How do the double-layer oil seals benefit long-term performance?

A: The dual high-elasticity dust-proof oil seals create a robust barrier against dirt, sediment, and moisture entering the oil circuit. This keeps the brake feel consistent over time — preventing pressure loss and maintaining reliable stopping performance across thousands of kilometers of use.

Q: What color options are available for the caliper shell?

A: The Motuda CNC caliper is available in multiple anodized color options including classic Black Gold, Matte Black, and Gold. Each finish is applied using a multi-layer hard anodizing process that is scratch-resistant and fade-resistant for long-term outdoor use.
