Dynamic Friction 633-46061L Disc Brake Rotor - Front Left

Overview

This Dynamic Friction disc brake rotor is built for direct fitment on select applications and features a drilled and slotted 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 633-46061L is listed for the front left position on select Buick Envision and Cadillac XT4 models.

Key Features

• Drilled and slotted rotor surface for improved heat management and pad cleaning.
• Vented construction for airflow through the rotor.
• Black zinc hat finish with rust-resistant coating for added corrosion protection.
• Directional braking surface for a specific rotation pattern.
• Five-bolt, 120 mm bolt circle fitment with 67.4 mm center hole diameter.

Detailed Description

The Dynamic Friction 633-46061L brake rotor is engineered as a vented disc rotor with a slotted and drilled friction surface. Its 321 mm outside diameter, 28 mm nominal thickness, and 25 mm discard thickness provide the dimensional profile needed for the listed applications. The plain disc finish is paired with a zinc black hat finish and rust-resistant coating to help resist surface corrosion in everyday driving conditions. This rotor is listed for select Buick Envision and Cadillac XT4 front left applications, including 2019-2026 Buick Envision and 2019-2025 Cadillac XT4 fitments. Part number 633-46061L is also identified by the same application reference across the listed vehicle coverage.

Common Issues This Part Addresses

• Brake pulsation caused by worn or uneven rotor surfaces.
• Reduced braking consistency from heat buildup in the rotor.
• Surface corrosion on exposed brake rotor areas.
• Noise and pad glazing associated with degraded rotor finish.
• Fitment mismatch when replacing a front left rotor on the listed vehicles.

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and center hole diameter before installation. Confirm the vehicle’s caliper configuration and front left application match the listed fitment, especially on 2021 Cadillac XT4 models with red or silver calipers. Clean the hub mounting surface before installing the rotor to help ensure proper seating and brake performance.

Quality Assurance

Dynamic Friction supplies this rotor as a fitment-specific replacement part for the listed applications. The drilled and slotted design, vented construction, and corrosion-resistant finishes reflect the product’s intended brake service use.
