Air Drum Brakes / Pneumatic Drum Brakes

⚙️ Exact 4-Hole OEM Engineering for Foton Auman
Our QT65CQ2-3501010 (LH) and QT65CQ2-3501020 (RH) Heavy Duty Air Drum Brake Assemblies are custom-engineered as drop-in replacements for Foton Auman heavy-duty truck axles. This specific variant features a precise φ400 × 150 mm (15.75″ × 5.91″) friction profile, seamlessly integrated with a standard 4-hole mounting pattern and a φ140 mm (5.51″) center bore. This configuration guarantees exact wheel-end hub alignment and concentric tolerance control.
🛑 High-Torque S-Cam Performance & Dynamic Stability
Designed to handle intense payload pressures, this foundation brake utilizes a heavy-duty S-Cam mechanical actuation system. The specialized 4-hole stamped steel backing plate provides superior torsional rigidity, effectively neutralizing warping during emergency braking. Paired with premium eco-friendly friction linings, it ensures consistent stopping power, minimal thermal fade, and extended service intervals in linehaul logistics networks.
🔬 Front Quality Assurance & Delivery Configuration
Manufactured under stringent IATF 16949 automotive quality protocols by Rizhao Renhe Auto Parts Technology Co., Ltd., every drum brake unit undergoes precise dimensional and load-bearing verification. The assembly is delivered to global buyers in a fully dressed, “Ready-to-Install” condition—complete with the backing plate, pre-lined brake shoes, return springs, and anchor pins, bypassing secondary shop assembly and reducing fleet downtime.
