Detailed Product Description

The DuraGo BR54119 disc brake rotor is engineered with a full cast iron construction to provide strength and resistance to warping under high heat conditions. Its vented design enhances airflow, helping to dissipate heat more effectively during braking, which is critical for maintaining consistent stopping power and rotor longevity. This rotor features a drum-in-hat design, integrating a parking brake drum within the rotor assembly, making it suitable for vehicles that require this configuration.

The rotor's non-directional brake surface allows for flexible installation without concern for rotor orientation. With 10 mounting bolt holes and a mounting bolt hole circle diameter of 6.43 inches (163.3 mm), it ensures a secure fit. The nominal thickness of 1.5 inches (38.2 mm) and discard thickness of 1.42 inches (36 mm) provide clear service limits for maintenance.

Compatible Vehicles and Applications

This DuraGo BR54119 rotor is compatible with various vehicle makes and models that require a 15.55-inch (395 mm) outside diameter vented rotor with a drum-in-hat design. It is commonly used on trucks and SUVs equipped with parking brake drums integrated into the rotor. Always verify fitment with your vehicle's specifications before purchase.

Common Issues Addressed by This Rotor

• Brake pulsation caused by warped rotors
• Reduced braking efficiency due to worn rotor thickness
• Overheating and brake fade during heavy braking
• Parking brake malfunction related to drum-in-hat rotor wear
• Corrosion and surface damage affecting rotor performance

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Check the mounting bolt holes and hub surface for damage or corrosion to guarantee proper fitment. Measure rotor thickness to confirm it meets or exceeds the nominal thickness of 1.5 inches (38.2 mm). Use a torque wrench to tighten mounting bolts to manufacturer specifications. Since this rotor does not include an ABS tone ring, verify compatibility with your vehicle's ABS system.
