PTENG PTU9 Universal Four Piston Brake Caliper – High-Performance Motorcycle Upgrade

Upgrade your motorcycle's stopping power with the PTENG PTU9 Large Radiation Four Piston Brake Caliper — a precision-engineered, CNC-milled aluminum alloy caliper designed for riders who demand consistent, confident braking in any condition. Whether you're commuting, canyon carving, or trail riding, this caliper delivers a sharp, responsive feel with every squeeze. Made in Mainland China.

🔧 Powerful, Responsive Braking

Symmetrical dual-piston synchronous push-plate design ensures even force distribution across brake pads for smooth, immediate response on both dry and wet road surfaces.
High wear-resistant sintered brake pads included — excellent heat resistance, slow wear rate, and reliable grip even in rainy conditions. Ideal for daily commuting and spirited mountain riding.
Imported high-elasticity oil seal structure provides superior dust and sediment resistance, preventing long-term oil seepage and preserving brake feel over thousands of kilometres.

🌡️ Advanced Heat Dissipation & Durable Construction

CNC precision-milled body ensures smooth internal oil channels and a fluid piston rebound — no sticking, no jamming, no unexpected brake fade.
Multi-channel heat dissipation groove design maximizes airflow around the caliper, so even prolonged, high-intensity braking stays firm and consistent.
Aviation-grade aluminum alloy construction delivers a lightweight yet rigid body that won't deform under hard riding. The anodized surface finish resists rust, scratches, and UV fading for long-lasting aesthetics.

🔩 Bolt-On Compatibility & Easy Modification

Standard crab-clamp mounting hole pattern — compatible with a wide range of motorcycles and electric bikes for a true universal fitment.
Direct OEM pump replacement — no frame grinding or disc modification required. Swap in with minimal effort and reduced modification costs.
Optional multi-color decorative adjustment screws let you personalize the look with a pop of contrast that complements any modified bike build.

✅ Factory Quality Assurance

Each caliper undergoes a factory high-pressure hydraulic seal test to verify zero oil leakage before shipping.
Ships as a complete kit including all installation screws and gaskets — ready to mount straight out of the box.
Packaged in an independent color gift box for secure transit protection, suitable for retail and international orders.

Frequently Asked Questions

Q: Is the PTENG PTU9 four piston brake caliper compatible with electric motorcycles?

A: Yes. The PTU9 uses a standard crab-clamp mounting hole pattern widely found on both conventional and electric motorcycles. It is designed as a direct OEM-style replacement, requiring no frame or disc modification for most compatible models.

Q: What brake pads come included with the PTU9 caliper?

A: The caliper ships with high wear-resistant sintered brake pads that offer excellent heat tolerance, slow wear, and consistent grip on both wet and dry road surfaces — suitable for commuting and performance riding alike.

Q: How is heat managed in the PTU9 caliper during intense braking?

A: The PTU9 features a multi-channel heat dissipation groove design that increases airflow around the caliper body, helping to manage heat buildup during sustained high-intensity braking and maintaining firm braking performance throughout.

Q: Does the caliper come ready to install, or do I need to buy additional hardware?

A: The PTU9 ships as a complete kit including sintered brake pads, all required mounting screws, and gaskets. No additional hardware purchases are necessary for a standard installation.
