Ensure your vehicle's safety and performance with our premium-grade brake caliper, engineered as a direct OEM replacement for various Lifan models. This critical component is responsible for housing the brake pads and using hydraulic pressure to clamp them onto the rotor, creating the friction necessary to slow or stop your vehicle effectively.
Manufactured to meet or exceed strict quality standards, this caliper is constructed from high-strength materials and features a corrosion-resistant finish for extended service life in diverse driving conditions. Its precision-machined pistons and seals are designed to prevent fluid leaks and ensure consistent, reliable braking force. Industry data showsthat properly functioning calipers are vital for maintaining optimal braking distance and pad wear. This unit arrives as a complete, ready-to-install assembly, promising a perfect fit and restoring your braking system to its peak operational condition, providing peace of mind with every journey.
Our brake calipers are manufactured to exact OEM specifications, ensuring a perfect, hassle-free installation. Utilizing advanced CNC machining and 3D scanning of original components, we guarantee dimensional accuracy within a 0.5mm tolerance. This precision engineering eliminates fitment issues, vibration, and uneven pad wear. Each unit is rigorously tested on fixture jigs to verify bolt alignment and piston travel, providing a direct, bolt-on solution that restores your vehicle's original braking integrity and performance without any modifications required.
Engineered for durability, our calipers are constructed with a high-grade cast iron body and feature an advanced E-coating + epoxy powder coat finish. This multi-layer protection has been proven to withstand over 50 hours of neutral salt spray testing (ASTM B117), significantly outperforming standard coatings. The internal components, including pistons and seals, are made from high-temperature resistant materials that maintain integrity and prevent fluid vaporization even under continuous operation at temperatures exceeding 300°F (149°C), ensuring consistent performance in demanding stop-and-go traffic.
At the heart of our caliper is a precision-machined piston and a high-quality sealing system. The piston is designed for smooth, consistent operation, preventing stick-slip and retraction issues that can lead to brake drag and premature pad wear. Our proprietary rubber compound seals are tested for over 500,000 cycles, offering exceptional resilience against wear and tear. This optimized hydraulic system ensures immediate brake response, firm pedal feel, and reliable, even-pressure application on the rotor for shorter, more predictable stopping distances.
Every caliper undergoes a stringent final inspection, which includes a 100% functional test where it is pressurized to 2,500 PSI and held for a minimum of 60 seconds to detect any potential leaks or seal failures. We deliver a complete, pre-assembled unit that includes the caliper bracket, mounting hardware, and a pre-bleed process. This "ready-to-install" approach saves valuable time for mechanics and DIY installers, reduces the risk of installation errors, and ensures optimal performance from the first use.
We go beyond basic standards by employing a High-Pressure Casting process for the caliper body, which increases its density and structural robustness. This caliper has undergone and passed simulated endurance tests equivalent to over 150,000 miles of real-world driving. This focus on superior material science and construction means our caliper resists warping, cracking, and fatigue under extreme stress, providing a reliable and long-lasting solution that you can trust for the lifetime of your vehicle.

Here are specific application scenarios of brake caliper:
This brake caliper is engineered for the demands of daily driving, providing reliable performance in heavy urban traffic. Its optimized hydraulic system ensures immediate and responsive braking during frequent stops, preventing the brake fade and sluggish pedal feel common in inferior products. The precision fit guarantees quiet operation and smooth engagement, enhancing driving comfort and safety on every journey to work, school, or running errands, mile after mile.
When traveling at higher speeds on highways, consistent and dependable braking power is non-negotiable. Our caliper provides stable clamping force and superior heat dissipation, maintaining optimal performance even during high-speed deceleration. The robust construction and high-temperature resistant seals prevent fluid vaporization and component failure, giving drivers the confidence to handle sudden stops or merge safely in fast-moving traffic conditions.
Driving on long, steep mountain descents or towing light loads places extreme stress on a braking system. This caliper is built to manage intense, prolonged heat buildup without performance degradation. Its high-temperature coating and durable piston seals resist wear and maintain consistent pressure on the rotors, effectively combating brake fade and ensuring controlled, stable deceleration where it matters most for vehicle and occupant safety.
Exposure to road salt, humidity, and frequent rain can quickly cause standard brake components to corrode and seize. Featuring a multi-layer corrosion-resistant coating tested to withstand 50+ hours of salt spray, this caliper is specifically designed for longevity in coastal or winter environments. This superior protection prevents piston seizure and bracket corrosion, ensuring reliable brake function and preventing costly repairs down the line.
For optimal performance and safety, we recommend professional installation. Before starting, always disconnect the vehicle's battery. Securely mount the new, pre-assembled caliper onto the knuckle, ensuring all bolts are torqued to the manufacturer's specified value, typically between 80-100 Nm. Connect the brake line and carefully bleed the system to remove all air, using fresh DOT 4 fluid. Before driving, press the brake pedal firmly several times to seat the pads against the rotor. Finally, conduct a low-speed test in a safe, controlled area to verify proper function and build confidence in your vehicle's restored braking system.
