Dynamic Friction 633-91003L Disc Brake Rotor - Front Left

Overview

Dynamic Friction 633-91003L is a drilled and slotted disc brake rotor built for specific compact car applications with a 258 mm front disc. It features a vented design, directional braking surface, and a black zinc hat finish with rust-resistant coating for added surface protection.

Compatible With Toyota Yaris, Mazda 2, Toyota Yaris iA, and Scion iA applications in the front left position, this rotor is sized for the listed bolt pattern and hub dimensions. The DFC Brake Rotor - Drilled and Slotted - Black line focuses on controlled braking surface design and corrosion protection for everyday service use.

Key Features

• Drilled and slotted braking surface for consistent pad contact and heat management.
• Vented rotor construction for improved airflow through the disc.
• Black zinc hat finish with rust-resistant coating for added corrosion protection.
• Directional brake surface matched to the listed application.
• 258 mm outside diameter with 4-lug fitment dimensions.

Detailed Description

This Dynamic Friction brake rotor, part number 633-91003L, is engineered around the listed fitments for Toyota Yaris, Mazda 2, Toyota Yaris iA, and Scion iA models. The slotted X drilled surface, vented construction, and directional braking face support stable braking performance while the plain disc finish and coated hat help manage exposed-surface corrosion. If you are replacing a worn front left rotor on a Toyota Yaris or Mazda 2, this part number 633-91003L matches the specified dimensions and mounting pattern for the application.

This part cross-references no interchange numbers provided for the same application.

Common Replacement Reasons

• Brake pulsation from rotor wear or uneven surface condition.
• Visible scoring, grooves, or heat checking on the braking face.
• Corrosion on the rotor hat or exposed metal surfaces.
• Reduced braking consistency from a worn front disc rotor.

Installation Notes

Verify rotor diameter, center hole diameter, bolt circle diameter, and lug hole dimensions before installation. Confirm the front left position and application-specific notes for your vehicle before ordering. Clean the hub mounting surface and inspect pads and caliper components during rotor replacement.

Quality Assurance

Dynamic Friction supplies brake components for service replacement applications, and this rotor uses a rust-resistant coating with a black zinc hat finish to support long-term surface protection.
