Product Details

Nugeon TechShield 360 99P01310B is a brake hydraulics component engineered as a rear left disc brake caliper for Subaru Legacy and Subaru Impreza models in the fitment list. The cast iron housing and steel piston provide the core hydraulic structure, while the E-coat finish helps protect the caliper surface.

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

Common Brake Issues This Part Can Address

• Rear brake drag caused by a sticking caliper piston or slide assembly
• Uneven rear braking from a worn or corroded caliper body
• Brake fluid leakage at the caliper or bleeder area
• Reduced braking performance from a damaged rear left caliper
• Noise or inconsistent pad contact related to caliper wear

Installation Notes and Tips

Verify rear left position, banjo bolt inlet style, M10-1.0 thread size, and bracket configuration before installation. Transfer or replace copper crush washers where applicable, and bleed the brake system after installation to remove air from the hydraulic circuit. Confirm pad fitment against the listed D471 pad reference and inspect the rotor, hose, and mounting points for wear before returning the vehicle to service.
