Dynamic Friction 631-54131L Disc Brake Rotor - Front Left

Drilled and Slotted Front Left Rotor

The Dynamic Friction DFC Brake Rotor - Drilled and Slotted - Silver, part number 631-54131L, is a vented disc brake rotor built for the front left position on select Ford trucks and SUVs. It features a slotted X drilled surface, zinc silver hat finish, and a rust resistant coating for a clean appearance and consistent braking surface.

Compatible With 1994-1996 Ford Bronco and 1994-1996 Ford F-150 front left rotor applications, this rotor is sized for a 298 mm outside diameter, 65 mm overall height, and 5-lug, 139.7 mm bolt circle fitment. The 631-54131L is a direct-fit style rotor for vehicles that use a directional brake surface and vented construction.

DFC Brake Rotor Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver line focuses on rotor surfaces that combine drilled holes and slots to help maintain a consistent contact area under braking. The silver zinc hat finish adds corrosion resistance at the hub area, while the plain disc finish keeps the braking surface straightforward for service and inspection.

• Slotted X drilled brake surface for front axle braking applications
• Vented rotor construction for heat management
• Rust resistant coating for added corrosion protection
• Zinc silver hat finish for a cleaner hub appearance
• 5-lug pattern with 139.7 mm bolt circle diameter
• Directional brake surface design

Detailed Product Description

Part number 631-54131L is a front left disc brake rotor for 1994-1996 Ford Bronco and 1994-1996 Ford F-150 models listed in the fitment data. It measures 298 mm in outside diameter, 26 mm nominal thickness, and 24.4 mm discard thickness, with a 98.5 mm center hole diameter and 16.4 mm bolt hole diameter. These dimensions matter when matching the rotor to the original brake setup on Ford Bronco and Ford F-150 front brake service.

Common Brake Issues This Rotor Can Address

• Uneven rotor wear on the front left brake corner
• Corrosion on the rotor hat or braking surface
• Brake pulsation caused by worn or out-of-spec rotors
• Reduced braking consistency from heat buildup in vented front rotors
• Service replacement for damaged or heavily worn front rotor assemblies

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and position before installation. This rotor is listed for the front left side only, so confirm the vehicle production date notes for 1995 Ford Bronco and 1995 Ford F-150 applications. Clean the hub mounting surface before installing the rotor, and inspect pads, caliper condition, and wheel hardware during brake service.

Quality Assurance

Dynamic Friction supplies this rotor as a specification-based brake component with rust resistant coating and a zinc silver hat finish for corrosion protection. Part number 631-54131L is listed for confirmed Ford Bronco and Ford F-150 fitment in the model years shown.
