Durable Cast Iron Disc Brake Rotor for Ram ProMaster
The DuraGo BR901278-02 disc brake rotor is engineered for reliable braking performance on Ram ProMaster 1500, 2500, and 3500 models. Designed with a vented, drum-in-hat construction, this rotor offers effective heat dissipation and consistent stopping power under demanding conditions.
- Constructed from full cast iron for strength and durability
- Vented rotor design to improve heat dissipation and reduce brake fade
- Rust resistant coating to extend rotor life and maintain appearance
- Disc brake rotor with 5 mounting bolt holes and drum-in-hat configuration
- Non-directional brake surface for versatile installation
- Compatible with Ram ProMaster 1500, 2500, and 3500 models
Technical Specifications and Features
The DuraGo BR901278-02 rotor features a nominal thickness of 0.87 inches (22 mm) and a discard thickness of 0.78 inches (19.9 mm), ensuring precise wear limits for safe operation. Its overall height measures 3.15 inches (80 mm), with an outside diameter of 11.81 inches (300 mm). The rotor includes a 3.11 inch (79 mm) center hole diameter and a mounting bolt hole circle diameter of 5.12 inches (130 mm) with five 0.7 inch (17.7 mm) bolt holes. The vented design promotes airflow to reduce heat buildup during braking, while the rust resistant coating helps prevent corrosion over time. This rotor does not include an ABS tone ring and features a non-directional braking surface for flexible installation options.
Applications and Problem Solving
- Replacement rotor for worn or warped disc brakes on Ram ProMaster 1500, 2500, and 3500
- Addresses brake fade caused by excessive heat through vented rotor design
- Helps restore braking performance and pedal feel
- Prevents rust and corrosion that can lead to uneven braking
- Compatible with drum-in-hat brake systems for integrated parking brake function
Installation Notes and Tips
When installing the DuraGo BR901278-02 rotor, ensure the mounting surface is clean and free of debris to maintain proper rotor alignment. Verify the rotor thickness is within discard limits before installation. This rotor is non-directional, allowing installation on either side of the vehicle. Use proper torque specifications for the 5 mounting bolts to avoid rotor warping. Since this rotor is designed for Ram ProMaster 1500, 2500, and 3500 models, confirm vehicle compatibility prior to installation.
