1. Application & Related Brake Parts
The DA03D Disc Brake Caliper Assembly is offered as a replacement component for compatible Dongfeng Tianlong heavy-duty truck disc brake systems.
The disc brake caliper works with the brake disc and friction pads to generate braking force. In an air disc brake system, the brake chamber operates the caliper mechanism, pressing the brake pads against the rotating brake disc to slow or stop the wheel.
Related components include brake discs, brake pads, brake chambers, brake carriers, guide pins, adjusting mechanisms, mounting bolts and caliper repair kits.
2. Fitment Confirmation Before Order
Buyers should confirm the complete part number DA03D, original axle identification, caliper design and installation dimensions before purchasing.
Important specifications include brake disc diameter, brake disc thickness, brake pad shape, mounting hole spacing, installation position and left-side or right-side configuration.
Different Dongfeng Tianlong models may use different axle and brake system configurations. Please compare the replacement with the original assembly before bulk purchasing.
The required supply scope should also be confirmed, particularly whether the order includes the caliper body, brake carrier, brake pads or additional mounting accessories.
