Sinotruk Heavy Truck Brake Bottom Plate AZ4075450060

The AZ4075450060 Brake Bottom Plate provides a rigid, heavy-duty mounting foundation for high-torque wheel braking systems. By maintaining precise structural alignment for brake shoe pivots and S-camshafts, this Sinotruk brake backing plate ensures balanced clamping pressure against the brake drum, preventing twisting or flex under maximum braking force.

Manufactured in ISO9001-certified facilities using drop-forged high-strength steel, the AZ4075450060 plate features high fatigue resistance and structural rigidity to endure severe thermal expansion and dynamic braking stress. Replacing a cracked, warped, or corroded backing plate with a brand-new AZ4075450060 unit restores exact brake shoe geometry, stops uneven lining wear, and shields internal brake components from road debris, water, and mud.
