Founded in 1998, our journey began as a precision workshop dedicated to the intricate world of automotive components. Over the past 27 years, we have evolved from a local manufacturer into a global titan in braking system technology. Our expertise spans the entire spectrum of brake caliper production, from the iconic 45210SH3931 series to advanced Electric Parking Brake (EPB) systems.
We don't just manufacture parts; we engineer safety. By integrating advanced CNC machining with rigorous testing protocols, BIT has become a primary choice for wholesalers and OEM partners across Europe, North America, and beyond.

The 45210SH3931 brake caliper is more than just a component; it is a critical safety element for millions of vehicles worldwide. Particularly prevalent in the aftermarket for Japanese and European passenger vehicles, this part number represents a high-volume demand sector for international wholesalers.
With the aging global vehicle fleet, the demand for high-reliability replacement calipers like the 45210SH3931 has surged. Distributors in North America and Europe are increasingly looking for factories that can provide OEM-matching performance at wholesale price points.
Used predominantly in compact and mid-sized sedans, the 45210SH3931 must withstand extreme thermal stress and corrosive environmental factors. Our manufacturing process ensures every unit meets these localized challenges head-on.
B2B procurement for 45210SH3931 has shifted toward "Supply Chain Resilience." Buyers now prioritize manufacturers like BIT that offer integrated logistics and a vast inventory of over 10,000 reference numbers.
The industry is rapidly shifting from mechanical to Electrical Parking Brake (EPB) systems. Our factory is at the forefront, producing EPB calipers with integrated actuators for the next generation of EVs.
Modern manufacturing now demands eco-friendly materials and energy-efficient CNC processes. BIT utilizes advanced waste-reduction techniques in our aluminum and cast-iron machining lines.
We are integrating AI-assisted visual inspection to detect microscopic flaws in caliper bores, ensuring 100% reliability for every 45210SH3931 unit that leaves our factory.
Once the raw caliper body is formed, it undergoes precision machining on Computer Numerical Control (CNC) machines. This critical stage involves:
With over 10,000 part numbers, we are a one-stop shop for passenger car braking systems. From 45210SH3931 to repair kits popular in Russia and South America.
Since 1998, we have mastered the nuances of the automotive aftermarket. We understand the specific needs of European distributors versus North American workshops.
Key markets include China (Domestic), Europe (Premium focus), North America (Scale focus), and Russia/South America (Cost-effective repair solutions).
By eliminating middle-men, we provide wholesale 45210SH3931 components at factory prices, allowing our partners to maintain healthy margins.
