Detailed Description

Nugeon 99P01630A is a front left disc brake caliper for the 1999, 2000, and 2001 Lexus RX300. It uses a cast iron housing with a steel piston and a single 60 mm piston bore, matching the listed brake hardware configuration for this vehicle position. The caliper arrives with the bracket installed for the application, along with caliper slides, dust boots, bleeder screw, and pad installation hardware where applicable. The gray E-coat finish adds corrosion resistance for everyday brake service conditions.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Part number 99P01630A is also a useful reference when verifying the correct front left Lexus RX300 brake caliper before service.

Common Brake Issues This Part Addresses

• Leaking brake fluid at the caliper body or bleeder area
• Uneven braking caused by a sticking piston or slide hardware
• Poor pad movement from worn caliper guides or dust boots
• Brake pull or inconsistent front left braking response
• Corrosion-related caliper seizure on the original unit

Installation Notes and Tips

Confirm front left placement and verify the banjo bolt connection, M10-1.0 inlet thread, and M7-1.0 bleeder thread before installation. Transfer brake pads only if they are serviceable, since pads are not included. Bleed the brake system after installation and inspect all sealing surfaces, copper crush washers, and hose connections for leaks. Use the vehicle’s brake pad specification D707 when selecting matching pads.
