This component, the "4. Back Of The Disc Corner Teeth 4.88", is a critical and precisely engineered part within your vehicle’s braking system. Specifically designed for optimal performance and safety, it refers to the set of teeth located on the rear outer edge (back) of a brake disc rotor, with a specified measurement or pitch of 4.88. This design is not merely incidental; it plays a fundamental role in the interaction between the brake disc and the wheel hub, ensuring perfect alignment and secure mounting.

The primary function of these corner teeth is to prevent any rotational slippage between the brake disc and the wheel hub assembly. When the wheel is mounted, these teeth interlock with corresponding gaps on the hub, creating a positive-lock connection. This ensures that the braking torque applied to the disc is directly and efficiently transferred to the wheel, without any loss of energy or independent movement. The precise 4.88 specification guarantees a perfect fit for its intended vehicle application, maintaining the structural integrity of the entire wheel assembly.

Using a correct and undamaged "4. Back Of The Disc Corner Teeth 4.88" is essential for vehicle safety. Worn, stripped, or incorrectly sized teeth can lead to improper disc seating, causing vibrations, uneven brake pad wear, pulsation in the brake pedal, and potentially dangerous braking inefficiency. When replacing brake discs, always ensure this component matches the OEM specifications for your vehicle. This attention to detail guarantees reliable braking performance, driver confidence, and the longevity of your braking system components. Always consult your vehicle’s manual or a professional for exact part compatibility.
