43512-37120 Front Vented Brake Disc for HINO 300 3.5T — 287x40mm 6-Hole Rotor
The Front Brake Disc (Rotor) with OEM reference number 43512-37120 is a verified direct-fit replacement for the HINO 300 series commercial trucks. This disc is a critical component of the braking system, mounted to the wheel hub and working in conjunction with the brake pads to slow and stop the vehicle.
When the brake pedal is pressed, the brake pads are pressed against the rotating disc, creating friction that converts kinetic energy into heat, ultimately slowing down or stopping the vehicle. A worn or damaged brake disc can lead to vibration or pulsation when braking, squealing or grinding noises, reduced braking performance, uneven brake pad wear, and increased stopping distances.
This OE‑spec replacement disc restores factory braking performance and safety. Manufactured to meet or exceed original equipment standards, this disc features a vented design for superior heat dissipation and is produced from high-quality grey cast iron (FC250 / G3000 equivalent) for reliable and safe braking-20.
