As a critical component of disc brake systems, our automotive brake calipers are engineered to deliver exceptional stopping power and reliability for passenger vehicles. These precision mechanisms function by housing brake pads and pistons that clamp onto rotating brake discs when hydraulic pressure is applied through the brake fluid, creating the friction necessary to slow or stop your vehicle .
Manufactured from high-strength materials including aluminum alloys and stainless steel, our calipers offer superior heat dissipation and corrosion resistance. The global brake caliper market, valued at approximately $7.9 billion in 2024, continues to grow steadily with the automotive industry . With dominant market shares in both single-piston (80%) and multi-piston designs, and serving primarily passenger vehicles (90%+ market share), our products meet rigorous international safety standards .
We supply both OEM and aftermarket calipers compatible with various vehicle brands, ensuring reliable performance, reduced braking noise, and enhanced safety for everyday driving and demanding conditions alike .
Our brake calipers are made of high-strength aluminum alloy material and optimized structural design, which significantly reduces weight compared to traditional designs. In some cases, the weight of a single brake can be reduced by up to 5 kilograms, effectively reducing the overall weight of the vehicle, thereby improving acceleration performance and fuel economy (or the range of electric vehicles). Lightweight design does not sacrifice strength, and through finite element analysis (FEA) optimization, it ensures excellent rigidity and deformation resistance even in high-pressure working environments. This design is particularly suitable for the dual demands of performance and efficiency in modern vehicles.
Equipped with a multi piston design (such as a 4-piston or 6-piston configuration), our calipers provide powerful and linear braking force. Its differentiated piston aperture design originates from racing technology, which can proportionally distribute clamping force to ensure uniform wear and stable performance of brake pads under various loads and temperatures. The unique heat dissipation fin design on the surface of the caliper draws inspiration from MotoGP technology, increasing the surface area of the piston exposed to air by 30% and significantly improving heat dissipation efficiency. This effectively suppresses the phenomenon of brake thermal attenuation, and even under continuous high-intensity braking conditions, it can maintain the best braking effect.
For electric vehicle optimization, our calipers will actively retract the brake pads after each brake, reducing the residual braking torque to below 0.2 Nm. This feature greatly reduces unnecessary rolling resistance and energy loss, making an important contribution to extending the range of electric vehicles. At the same time, ensuring the optimal air gap and uniform distribution between the brake pads and brake discs achieves almost lossless operation, improving overall energy efficiency.
We use high-quality materials such as aerospace grade aluminum alloy, ductile iron, and stainless steel hardware for manufacturing. The caliper body is treated with hard anodizing or coated with powder (such as black or silver) to provide excellent corrosion protection and durability. Stainless steel pistons can effectively resist corrosion and reduce heat transfer from brake pads to caliper bodies and brake fluid, maintaining stable hydraulic performance. These materials and technologies ensure the long-term service life and reliability of the product in various harsh environments.
Every brake caliper undergoes 100% high and low temperature pressure testing before leaving the factory to ensure that it meets or exceeds the strict performance, driving, and durability standards of the original equipment manufacturer (OEM). We offer multiple installation options (such as radial installation) and wide compatibility, suitable for many popular small car models and brake discs of different sizes (such as up to 16 inch diameter rotors). Accurate manufacturing and rigorous testing processes ensure the reliability, safety, and plug and play convenience of the product.

Here are specific application scenarios of brake caliper:
Our brake calipers provide reliable stopping power for city traffic conditions, featuring precise hydraulic response and heat dissipation for frequent stop-and-go driving. With over 75% of passenger cars using floating caliper designs for urban environments, our products offer OEM-compatible performance with 100% pressure testing validation to ensure safety during daily commutes, school runs, and grocery trips.
Engineered for enthusiasts and sports vehicles, our fixed-type multi-piston calipers (4/6-piston configurations) deliver enhanced braking force and superior heat resistance during aggressive driving. Tests show 35% better heat dissipation versus standard calipers, preventing brake fade during repeated hard stops. Ideal for mountain roads, track days, and high-performance sedans requiring shorter stopping distances.
Specifically optimized for EVs, our calipers address regenerative braking integration and increased vehicle weight (EVs average 20-30% heavier than ICE vehicles). Featuring low-drag designs with residual torque below 0.2 N·m to extend range, and compatible with electronic parking brake (EPB) systems. Supports extended brake life despite higher mass and reduced friction brake usage.
Built to perform in extreme conditions with corrosion-resistant materials (stainless steel pistons, powder-coated bodies) and advanced sealing systems. Independent testing verifies operation from -40°C to 200°C, ensuring reliable performance in snowy, salty, rainy, or dusty environments. Particularly suitable for areas with severe winters or coastal regions where salt corrosion is common.
Track-proven calipers offering maximum stiffness and minimal weight through forged aluminum construction. Used in professional racing series including Le Mans 24H and FIA-certified competitions. Provides consistent pedal feel and braking performance under extreme track conditions, with rapid heat dissipation through integrated cooling technologies.
Proper installation is crucial for optimal performance. Always use DOT 4 brake fluid and tighten mounting bolts to manufacturer's specified torque values (typically 70-100 N·m). After installation, perform a bed-in procedure by completing 20-30 moderate stops from 50 km/h to 10 km/h, allowing cooling intervals. This creates proper pad transfer layer on rotors, ensuring 90% faster braking response. Test system at low speed before normal driving. Regularly check for leaks and wear every 15,000 km. Our calipers meet SAE J2522 performance standards for reliable operation.
