Bmw Heavy Duty Solid Brake Discs

Brake Discs Features:                                                   

•Equivalent to OE design 

•Smooth and quick stop 

•Anti-rust 

•Low noise, low dust 

•Optimal thermal performance 

•Use of high-carbon alloy provides high heat resistance, prolongs service life, and offers consistent performance.

•Vented designs and double-layer help dissipate heat efficiently, combating brake fade during continuous braking.

•Precision manufacturing ensures stable performance. Heat treatment and long-term aging treatment optimize stability and strength.

•Large-size disc design provides high braking force and, when matched with specific pads, can help shorten braking distances.

•The matching brake pads feature a heavy‑duty specific friction material formulation, tuned to the thermal characteristics of solid discs (which dissipate heat more slowly). The design objective of this formulation is to maintain a stable friction coefficient under conditions where solid discs heat up more quickly – such as consecutive downhill driving or heavy‑load braking. The formulation incorporates a higher proportion of high‑temperature binder and heat‑resistant fibres to reduce thermal decomposition and accelerated wear at elevated temperatures. Additionally, the recovery characteristic of this formulation is optimised – after short periods of high‑intensity braking, the pads quickly regain friction performance during cooling, matching the intermittent braking patterns typical of urban driving.

•Rear‑axle brake pads have different NVH and dust priorities compared with front‑axle pads. The rear wheels are closer to the passenger cabin, making brake noise more perceptible to occupants. This product’s matching pads prioritise low noise performance in their formulation design, optimising the damping characteristics and compressibility of the friction material to reduce low‑frequency rumble and high‑frequency squeal during rear‑axle braking. The formulation also adopts a low‑metallic system, reducing dust generation and keeping rear wheels relatively clean. This characteristic is especially important for BMW X5, X7, and other SUVs that emphasise ride comfort.
