Dynamic Friction 633-47028L Disc Brake Rotor - Front Left

Overview

This Dynamic Friction disc brake rotor is built for specific front left applications and uses a slotted, drilled surface with a vented design. The black zinc hat finish and rust-resistant coating add corrosion protection, while the directional braking surface supports consistent pad contact. Part number 633-47028L is a fitment-specific replacement for select Chevrolet, Pontiac, and Oldsmobile models.

Key Features

• Slotted and drilled rotor surface for improved heat management and pad bite.
• Vented rotor construction for airflow through the braking surface.
• Black zinc hat finish with rust-resistant coating for added corrosion protection.
• Directional brake surface for a defined rotation pattern.
• 5-lug bolt pattern with 118 mm bolt circle and 70.5 mm center hole.

Detailed Description

Dynamic Friction 633-47028L is a disc brake rotor engineered for front left fitment on select Chevrolet Malibu, Chevrolet Classic, Pontiac Grand Am, Oldsmobile Alero, and Oldsmobile Cutlass applications. The rotor measures 278 mm outside diameter with a 26 mm nominal thickness and 24.7 mm discard thickness, giving buyers the dimensional details needed for a proper brake service match. Its slotted X-drilled surface and vented construction are paired with a directional braking face to support stable braking performance under repeated use. The black zinc hat finish and rust-resistant coating help protect exposed surfaces from corrosion. This part number, 633-47028L, is a direct replacement choice for drivers servicing compatible GM platforms.

Common Uses

• Replacing a worn or below-spec front left brake rotor.
• Addressing brake pulsation caused by rotor wear or surface variation.
• Restoring braking response when the rotor surface is heat-checked or scored.
• Servicing corrosion-damaged rotor surfaces on compatible vehicles.
• Matching the correct rotor dimensions during brake repair on GM applications.

Installation Notes

Verify rotor diameter, thickness, bolt pattern, center hole diameter, and position before installation. This rotor is listed for front left applications only, so confirm the vehicle side and brake configuration against the fitment data. Part number 633-47028L should be matched to the exact application shown for Chevrolet, Pontiac, and Oldsmobile models.

Quality Assurance

Dynamic Friction supplies brake components with application-specific engineering and corrosion-resistant finishes. The 633-47028L rotor is built to the listed dimensional and fitment requirements for the confirmed vehicles.
