Common Repair Uses

  • Replacing a cracked or hardened brake master cylinder reservoir cap gasket
  • Restoring a proper seal at the brake fluid reservoir cap
  • Addressing brake fluid seepage around the master cylinder reservoir opening
  • Servicing older Ford, Lincoln, and Mercury brake master cylinder assemblies
  • Maintaining reservoir cap sealing on vehicles with original gasket wear

Installation Notes and Tips

Inspect the reservoir cap and master cylinder sealing surface before installation. Clean away brake fluid residue and debris so the new gasket seats evenly. Verify the vehicle’s exact brake system configuration, including notes such as hydraulic booster, electronic stability control, ABS, or slot count where listed in fitment.
