Carlson 15309 Rear Disc Brake Caliper Repair Kit

Carlson 15309 is a rear disc brake caliper repair kit for select Mitsubishi Lancer and Subaru Impreza applications. It includes the boot and square cut seals needed to restore caliper sealing and release action during normal brake operation.

Key Features

• Disc brake caliper repair kit for rear applications
• Includes boot and square cut seals for caliper service
• Supports proper apply and release cycle operation
• Built for select Mitsubishi Lancer and Subaru Impreza rear disc brake calipers
• Carlson part number 15309 for application-specific service work

Detailed Description

This Carlson caliper repair kit is designed for rear disc brake service on 2003-2006 Mitsubishi Lancer, 2009-2011 Mitsubishi Lancer, 2012-2013 Subaru Impreza, and 2013-2014 Mitsubishi Lancer applications. The boot and square cut seals help the caliper maintain sealing integrity so the piston can move and return as the brake system cycles. If you are servicing a rear disc brake caliper on a Mitsubishi Lancer or Subaru Impreza, Carlson 15309 provides the sealing components needed for that repair.

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

What It Is Used For

• Leaking caliper seals at the rear disc brake caliper
• Sticking or slow-return caliper piston movement
• Brake drag caused by worn sealing components
• Brake fluid seepage around the caliper piston area
• Service work on rear calipers for Mitsubishi Lancer and Subaru Impreza models

Installation Notes and Tips

Clean the caliper thoroughly before assembly and inspect the piston, bore, and slide surfaces for wear or corrosion. Replace damaged components as needed so the new seals can seat correctly. Confirm rear disc brake caliper identification before ordering, since fitment varies by vehicle and caliper type.

Quality Assurance

Carlson designs brake service parts around system-level operation, with sealing components selected to help the caliper function through the apply and release cycle as intended.
