Detailed Product Description
The DuraGo BR31070 disc brake rotor is engineered as a full cast, solid rotor made from cast iron, ensuring durability and effective heat management during braking. Its nominal thickness of 0.39 inches (10 mm) and discard thickness of 0.31 inches (8 mm) provide clear service limits for maintenance. The rotor features a conventional design without cross-drilling or slotting, which suits vehicles like the Acura Legend and Honda Prelude that require reliable, straightforward braking components. The rotor’s dimensions, including a 10.24-inch (260 mm) outside diameter and a 1.69-inch (43 mm) overall height, match OEM specifications for proper fitment and performance. With four mounting bolt holes arranged on a 4.5-inch (114.3 mm) circle, and a center hole diameter of 2.52 inches (64 mm), installation aligns precisely with the brake assembly of compatible vehicles.
Common Applications and Problem Solving
- Replacement for worn or warped rotors on Acura Legend and Honda Prelude
- Addresses brake pulsation caused by uneven rotor surfaces
- Resolves reduced braking efficiency due to rotor thickness below discard limits
- Eliminates noise and vibration from damaged or corroded rotors
- Restores proper rotor dimensions for safe and consistent braking
Installation Notes and Tips
- Ensure rotor thickness is measured before installation to confirm discard limits
- Clean rotor surface and hub mounting area to prevent uneven wear
- Torque mounting bolts to manufacturer specifications for secure fitment
- Inspect brake pads and replace if worn to maintain optimal braking performance
- Check for ABS sensor clearance as this rotor does not include an ABS tone ring
