• Four mounting bolt holes with a 100 mm bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Detailed Product Description

The DuraGo BR5474 disc brake rotor is constructed from full cast iron, providing a solid and reliable braking surface. Its vented design allows air to flow between the rotor faces, reducing heat buildup and minimizing brake fade during extended use. With a nominal thickness of 0.87 inches (22 mm) and a discard thickness of 0.79 inches (20 mm), this rotor meets the specifications required for safe and effective braking. The rotor features a 10.11-inch (256.8 mm) outside diameter and an overall height of 1.78 inches (45.1 mm), ensuring proper alignment and fitment on compatible vehicles. The four mounting bolt holes with a 100 mm bolt circle diameter and 0.51 inch (13 mm) diameter provide secure attachment to the hub assembly. This rotor is designed as a conventional, non-directional brake surface without cross-drilling or slotting, suitable for standard braking applications.

Compatible Vehicles and Applications

This DuraGo BR5474 disc brake rotor is compatible with the following makes and models:

• Ford Escort
• Mazda MX-3
• Mazda Protege
• Mercury Tracer

It is intended for use in front or rear disc brake systems where a vented, conventional rotor is specified.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive brake fade due to poor heat dissipation
• Uneven brake pad wear from damaged or worn rotors
• Reduced braking efficiency from rotor surface corrosion
• Noise or pulsation caused by rotor thickness below discard limits

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below 0.79 inches (20 mm)
• Clean rotor surface to remove any protective coatings or debris
• Ensure mounting bolt holes align properly with hub assembly
• Torque mounting bolts to manufacturer specifications to avoid rotor distortion
• Inspect brake pads and calipers during rotor replacement for optimal performance
