Product Details and Specifications

The DuraGo BR54090-01 is a solid disc brake rotor featuring a drum-in-hat design, which integrates the parking brake drum within the rotor assembly. This design is commonly used on rear brakes of trucks and SUVs, providing both disc braking and drum parking brake functionality. The rotor is made from cast iron, a material known for its excellent heat dissipation and durability under heavy braking conditions. The rotor’s nominal thickness of 0.55 inches (14 mm) ensures a long service life, while the discard thickness of 0.47 inches (12 mm) signals when the rotor should be replaced to maintain safe braking performance.

With an outside diameter of 13.15 inches (334 mm) and an overall height of 2.24 inches (57 mm), this rotor is designed to fit vehicles requiring a 5-bolt mounting pattern with a 5.31 inch (135 mm) bolt circle diameter. The mounting bolt holes measure 0.62 inches (15.7 mm) in diameter. The rotor does not include an ABS tone ring and features a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Ford F-150 (including Heritage models)
• Ford Expedition
• Lincoln Navigator
• Lincoln Blackwood

This rotor is specifically designed for rear disc brake systems with drum-in-hat parking brake configurations on these Ford and Lincoln trucks and SUVs.

Common Issues Addressed by This Rotor

• Brake rotor wear and thinning beyond safe limits
• Corrosion and rust buildup on brake rotors
• Uneven braking or brake pulsation due to rotor warping
• Reduced braking efficiency from damaged or worn rotors
• Parking brake functionality issues related to drum-in-hat rotor design

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 0.55 inches (14 mm). Clean the hub surface thoroughly to prevent rotor runout and ensure proper seating. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for orientation. Verify compatibility with your vehicle’s brake system, especially the drum-in-hat parking brake setup, before installation.
