Product Details

This Nugeon brake caliper is built for the rear right brake hydraulics position on the Lexus LS400 and includes the bracket, slides, dust boots, and brake pad installation hardware noted in the product data.

For this application, that means a rear right Lexus LS400 caliper assembly prepared for brake service and replacement work.

Common Brake Issues This Part Addresses

• Rear brake drag caused by a sticking caliper piston or slide hardware
• Uneven rear braking on a 1998-2000 Lexus LS400
• Brake fluid leakage at the caliper body or bleeder area
• Corrosion-related caliper wear on the rear right corner
• Poor pad movement from worn caliper hardware

Installation Notes

Verify the rear right position, bracket style, inlet fitting type, and thread sizes before installation. This caliper uses a banjo inlet fitting with M10-1.0 inlet port threads and an M7-1.0 bleeder screw thread. Confirm brake hose and banjo bolt compatibility, and transfer or replace copper crush washers where applicable during brake line connection.

Because this is a brake hydraulic component, bleed the system after installation and inspect for leaks, proper slide movement, and even pad contact. Use the vehicle’s service procedure for torque values and brake fluid bleeding sequence.
