Product Details

The Carlson Disc Brake Caliper Repair Kit line focuses on restoring the sealing components that keep a hydraulic caliper operating correctly. For front brake service on Infiniti Q50, Infiniti Q60, and Nissan 370Z models, part number 15400 provides the boot and square cut seals needed to address worn caliper seals and maintain consistent brake response. This kit is listed for front applications across 2008-2023 model years, including Brembo brake and D1346-specific fitments where noted.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Kit Can Address

• Brake fluid seepage at the caliper seal area
• Sticking or slow-return caliper piston movement
• Uneven front brake feel caused by worn sealing components
• Loss of caliper sealing integrity during service
• Brake drag related to deteriorated boots or square cut seals

Installation Notes

• Verify front caliper configuration before ordering, including Brembo, Sport Package, or D1346 notes where listed.
• Inspect the caliper bore, piston, and slide surfaces for wear or corrosion before reassembly.
• Clean all sealing surfaces thoroughly to help the new seals seat correctly.
• Use the exact vehicle fitment listing for your Infiniti or Nissan model, since coverage varies by year and brake package.
