Product Details

Nugeon 99P01254B is a rear left brake caliper assembly for Mitsubishi Eclipse and Mitsubishi Galant applications listed above. The TechShield 360 line focuses on corrosion resistance and service-ready brake hydraulics, and this unit includes the bracket, slides, dust boots, and bleeder screw needed for a complete caliper replacement on the specified position. The caliper uses a 35 mm steel piston, cast iron housing, and M7-1.0 bleeder thread specification.

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

Common Brake Issues This Part Addresses

• Rear brake drag caused by a sticking caliper piston or slide hardware
• Uneven rear braking on the left side
• Brake fluid seepage at the caliper body or bleeder area
• Corrosion-related caliper seizure on older Mitsubishi brake systems
• Reduced braking response from a worn remanufactured caliper assembly

Installation Notes and Tips

Verify rear left position, inlet thread size, and banjo bolt connection before installation. Transfer only the components required by the vehicle application, and bleed the brake system after installation to remove air from the hydraulic circuit. Inspect brake hoses, pads, and rotor condition during service to confirm the repair is complete.
