Extended Product Information

FAQs

Are these bolts universal?

No, Wilwood Brake Rotor Bolts are application-specific. You must ensure you have the correct thread size and length for your particular Wilwood rotor and mounting hat.

What material are these bolts made of?

These bolts are made from high tensile steel, ensuring strength and durability for demanding braking conditions.

Do I need to use the included washers?

Yes, the included washers are essential for distributing clamping force evenly across the mounting surface and should always be used.

What torque specification should I use?

Torque specifications vary depending on the specific application. Always refer to the official Wilwood technical documentation for your brake kit or rotor/hat assembly for the correct torque values.

How many bolts are typically in a pack?

Pack quantities can vary. Common pack sizes include 8 or 12 bolts, depending on the specific product number and application requirements.

Can I reuse old brake rotor bolts?

It is generally not recommended to reuse critical fasteners like brake rotor bolts, especially if they show any signs of wear or damage. Always use new, correctly specified bolts for safety and reliability.

Troubleshooting

Bolts do not thread into the mounting hat.

Verify you have the correct thread size and pitch for your application. Ensure the hat's threaded holes are clean and free from damage or debris.

Rotor feels loose after installation.

Ensure all bolts are tightened to the manufacturer's specified torque. Re-check the torque values and tighten in a star pattern. Confirm the correct bolt length is being used, not too short or too long.

Difficulty finding the correct bolt size.

Consult your Wilwood brake kit documentation or contact Wilwood technical support with your specific rotor and hat part numbers to identify the correct bolt specification.

Setup, Compatibility & Care

Setup:

  1. Identify the correct bolt size and thread pitch required for your specific Wilwood brake rotor and mounting hat combination. Refer to your brake kit documentation or Wilwood's specifications.
  2. Ensure the mounting surfaces of the rotor and hat are clean and free of debris.
  3. Insert the bolts through the rotor and into the hat.
  4. Place a washer onto each bolt before fully seating.
  5. Tighten the bolts incrementally and in a star pattern to ensure even pressure.
  6. Torque the bolts to the manufacturer's specified value using a torque wrench. Refer to the Wilwood technical documentation for precise torque specifications.

Compatibility:

These bolt packs are *application-specific*. Always verify the MPN (e.g., 230-8390 for 5/16" - 18 x 1") and thread size against your brake rotor and hat specifications. Wilwood offers various sizes, such as:

  • 5/16" - 18 Thread x 1" Long (Pack of 8)
  • 5/16" - 18 Thread x 1" Long (Pack of 12)
  • 1/4" - 20 Thread x 3/4" Long (Pack of 12)

Care:

These are high-strength fasteners. Inspect them periodically for any signs of wear, corrosion, or damage. If any damage is observed, replace the bolts immediately. No special cleaning is typically required beyond ensuring the threads are clean during installation.
