DuraGo BR901370 Disc Brake Rotor - Front

DuraGo BR901370 Front Brake Rotor

The DuraGo BR901370 is a front disc brake rotor built for Ford Transit and E-Transit applications that require a 111.5 mm bolt circle diameter. It uses full cast iron construction with a vented design to support consistent braking performance on daily-duty commercial vans.

For Ford Transit-150, Transit-250, Transit-350, and E-Transit front brake service, this rotor matches the listed OE-style dimensions and mounting pattern. The BR901370 is a direct-fit replacement for vehicles that call for a 12.13-inch outside diameter and M10 x 1.25 bolt size.

Key Features

• Cast iron, full cast construction for dependable braking strength
• Vented rotor design for front axle heat management
• 12.13 in. outside diameter with 1.18 in. discard thickness
• 1.30 in. nominal thickness and 2.17 in. overall height
• 5-bolt mounting pattern with 111.5 mm bolt circle diameter

Product Details

DuraGo manufactures aftermarket brake components through ISO-certified factories with attention to fit, form, and function. The BR901370 front brake rotor is engineered for Ford Transit front brake applications from 2015-2026, including 2015-2019 Transit-150, Transit-250, and Transit-350; 2020-2021 Transit-150, Transit-250, and Transit-350 except 4,600 lb. front axle; 2022-2023 Transit-150, Transit-250, and Transit-350 except heavy duty front axle; and 2022-2026 E-Transit front. This part cross-references Ford OE numbers such as CK4Z1125A and CK4Z1125C for the same application.

Common Problems This Rotor Helps Address

• Brake pulsation caused by worn or out-of-spec front rotors
• Reduced braking consistency from heat-affected rotor surfaces
• Service issues on Ford Transit front brake repairs with the wrong bolt pattern
• Fitment problems when replacing a rotor with the incorrect diameter or center bore
• Noise or uneven contact from a rotor that no longer meets discard thickness

Installation Notes and Tips

Verify the vehicle’s front axle configuration before ordering, especially on 2020-2023 Transit models with axle exclusions noted in the fitment data. Confirm the 111.5 mm bolt circle diameter, 5 mounting holes, and center hole diameter before installation. For 2025-2026 E-Transit applications, axle hub, brake rotor, and caliper bracket bolts are one-time use and must be replaced after removal; torque all fasteners to factory specifications using the correct procedure.

Quality Assurance

DuraGo brake rotors are produced in ISO-certified factories and built to meet requirements for fit, form, and function. The BR901370 is manufactured to support consistent service quality for Ford Transit and E-Transit front brake maintenance.
