• Material: Cast iron for strength and heat dissipation
• Construction: Full cast design for structural integrity
• Type: Vented disc brake rotor to improve cooling
• Dimensions: 11.81 inch (300 mm) outside diameter and 3.15 inch (80 mm) overall height
• Mounting: 5 bolt holes with 0.7 inch (17.7 mm) diameter and 5.12 inch (130 mm) bolt circle diameter
• Rust-resistant coating to reduce corrosion and extend rotor life
• Drum-in-hat design with non-directional brake surface

Technical Details and Construction

The BR901278-01 rotor features a full cast iron construction, which balances durability and heat management. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reduce the risk of brake fade. The rotor’s nominal thickness is 0.87 inches (22 mm), with a discard thickness of 0.78 inches (19.9 mm), ensuring it meets safety standards for wear limits. The drum-in-hat configuration integrates a parking brake drum, compatible with the Ram ProMaster’s braking system requirements.

Compatible Ram ProMaster Models

This disc brake rotor is specifically compatible with Ram ProMaster 1500, 2500, and 3500 models. The precise fitment ensures proper alignment and secure mounting using the 5-bolt pattern, making it suitable for vehicles requiring the BR901278-01 part number.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor corrosion and surface rust issues
• Improving braking performance on Ram ProMaster 1500, 2500, and 3500
• Restoring proper rotor thickness to maintain safe braking distances
• Ensuring compatibility with drum-in-hat parking brake systems

Installation Notes and Tips

When installing the DuraGo BR901278-01 rotor, ensure the mounting surface is clean and free of debris to prevent uneven rotor seating. Verify the rotor thickness before installation to confirm it meets the minimum discard thickness. Use proper torque specifications for the 5 mounting bolts to maintain secure attachment. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle’s ABS system if applicable.
