Dongfeng KC truck parts brake valve Bracket assembly 3514020-C0400

Built to withstand the mechanical stress of the Dongfeng KC’s brake system (including vibration, brake fluid pressure fluctuations, and heavy loads), the bracket features a reinforced steel structure. The main body is crafted from 5mm-thick high-strength carbon steel (Q355 grade) with integrated triangular reinforcing ribs at stress points (e.g., valve mounting lugs and chassis connection areas). This design enhances torsional rigidity by 40% compared to standard flat brackets, preventing bending or deformation even under maximum brake system pressure (up to 1.2 MPa). The bracket’s valve mounting surface is precision-machined to a flatness tolerance of ≤ 0.1mm, ensuring the brake valve sits perfectly level—critical for maintaining consistent fluid flow and avoiding valve sticking. Rigorous load testing confirms the bracket can endure 100,000+ brake cycles without structural damage, meeting the demands of commercial truck use

Exposed to road salt, rain, mud, and humidity (common in truck operation), the bracket requires robust corrosion resistance. It undergoes a three-step surface treatment process: first, a zinc phosphate coating to create a porous base that enhances coating adhesion; second, an electrophoretic primer (E-coat) that seals all crevices (including weld joints and mounting holes) for uniform protection; third, a black powder coating (180μm thickness) that resists chipping, scratching, and chemical damage from brake fluid or de-icing agents. This system enables the bracket to pass 800 hours of neutral salt spray testing without rust or coating peeling—far exceeding the industry standard of 500 hours for truck chassis components. The coating also remains stable in extreme temperatures (-40°C to 150°C), ensuring the bracket maintains structural integrity and performance for over 8 years

This bracket is engineered to work seamlessly with Dongfeng KC’s original brake system, ensuring optimal safety and performance. It includes pre-punched holes for brake fluid line clips, keeping hydraulic lines organized and preventing contact with moving chassis components (which could cause line wear or leaks). The bracket’s design also creates 15mm of clearance between the brake valve and adjacent parts (e.g., wiring harnesses, fuel lines), avoiding interference that could damage components or restrict valve operation. Additionally, the bracket features a built-in grounding tab that connects to the chassis, reducing electromagnetic interference (EMI) with the brake system’s electronic sensors—critical for trucks equipped with anti-lock braking systems (ABS) or electronic stability control (ESC). This compatibility ensures the bracket integrates perfectly with the truck’s safety systems, maintaining compliance with international brake safety standards (ECE R13, FMVSS 105)

Engineered for efficient replacement in truck repair shops, this bracket simplifies installation with user-friendly features. It comes with pre-assembled mounting hardware (high-tensile M8 bolts, lock washers, and nuts) that match Dongfeng KC’s OEM specifications—no need for separate parts procurement. The bracket has laser-etched alignment marks that align with reference points on the chassis, guiding technicians to position it accurately in 20–25 minutes using standard hand tools (no specialized equipment required). To guarantee quality, the product is manufactured in an IATF 16949 certified facility, with each unit undergoing strict inspections: dimensional checks via 3D coordinate measuring machines, load tests to confirm strength, and coating adhesion tests. It also includes a 36-month warranty against manufacturing defects (e.g., weld failure, material cracking, or coating peeling), providing Dongfeng KC truck owners and fleet operators with long-term peace of mind and minimal brake system downtime
