Detailed Description

Nugeon 99P01691B is a rear left disc brake caliper for Lexus ES350, Toyota Avalon, and Toyota Camry models listed above. The TechShield 360 line focuses on corrosion protection, while the remanufactured aluminum housing and steel piston provide a direct-fit hydraulic brake service part for rear disc brake repair. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues This Part Addresses

• Leaking caliper seals or fluid loss at the rear brake corner
• Sticking or seized piston movement
• Uneven rear brake pad wear on the left side
• Corrosion on the caliper body or bleeder area
• Brake drag, pull, or reduced rear braking response

Installation Notes and Tips

Verify rear left position, inlet thread size, and mounting bracket style before installation. Use the correct banjo bolt and copper crush washers where applicable, and confirm the vehicle-specific mounting bolt size noted in fitment. Bleed the brake system after installation and inspect for leaks, pad alignment, and rotor contact before returning the vehicle to service.

Quality Assurance

Built as a remanufactured brake hydraulic component under Nugeon’s TechShield 360 line, this caliper is prepared for corrosion-resistant service and application-specific fitment on the listed Lexus and Toyota models. Confirm all vehicle notes, including production date and manufacturing origin, to match the correct rear left application.
