Founded in 1998, Wenzhou BIT Automobile Parts Co., Ltd. has evolved from a specialized workshop into a global powerhouse in braking technology. Our journey reflects the evolution of the Chinese automotive industry itself—moving from simple component production to complex, high-precision engineering.
Our expertise isn't just in manufacturing; it's in quality assurance. We understand that every brake caliper or repair kit we ship carries the responsibility of passenger safety. This commitment has made us a trusted partner for international trading companies and OEM service providers worldwide.
Once the raw caliper body is formed, it undergoes precision machining on Computer Numerical Control (CNC) machines. This includes rough machining to remove excess material and fine machining to create precise dimensions for piston bores, mounting points, and fluid passages.
Tolerances are kept extremely tight. We employ high-pressure testing to ensure zero leakage and thermal stability tests to guarantee performance under extreme braking conditions. Every 43210-SV4-A02 related component follows these strict protocols.
We work closely with clients to develop custom solutions, adapting to regional requirements such as the high-salt environments of Northern Europe or the intense heat of Middle Eastern deserts.
