Detailed Description

Nugeon 99P01653B is a rear left disc brake caliper engineered for brake hydraulic replacement on select Toyota and Lexus platforms. It uses a cast iron body with a steel piston and rust preventative coating to support consistent brake operation in the rear braking circuit. The included bracket, slides, dust boots, and hardware simplify matching the original caliper layout where applicable.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you are replacing a worn rear left caliper on a Toyota 4Runner, Lexus GX460, Lexus GX470, or Toyota Sequoia, part number 99P01653B provides the fitment and hydraulic connection details needed for a direct replacement search.

Common Problems This Caliper Can Address

• Brake fluid leakage from a worn caliper body or piston seal area
• Uneven rear brake pad wear on the left side
• Sticking or dragging rear brake operation
• Corrosion on the caliper housing or piston area
• Bleeder screw service issues during brake maintenance

Installation Notes and Tips

Verify rear left fitment against the vehicle listing before ordering. Confirm the banjo bolt inlet connection, M10-1.0 inlet thread size, and bleeder screw thread size match the original brake setup. Transfer or replace brake pads as needed, since pads are not included. Follow proper brake bleeding procedures after installation and inspect the brake hose, mounting points, and rotor condition before returning the vehicle to service.
