Brembo 08.A038.11 Disc Brake Rotor - Rear

Brembo UV Coated Rear Rotor

Brembo 08.A038.11 is a rear disc brake rotor built as an OE-equivalent replacement for select Lexus applications. It uses grey cast iron construction and a UV-coated surface to help protect the rotor, including the braking plate surfaces, while supporting consistent braking performance.

This rotor line is part of Brembo’s Premium UV Coated OE Equivalent Rotor range, which focuses on direct replacement fitment, corrosion protection, and practical serviceability for everyday driving. For Lexus GS300, GS430, IS300, LS400, SC400, and SC430 rear brake service, 08.A038.11 is specified for the listed applications below.

Key Features

• Grey cast iron construction for stable braking performance
• UV-coated rust-resistant surface for added protection
• Solid rotor design with 307 mm outside diameter
• 5-hole bolt pattern with 62 mm centering diameter
• Nominal thickness: 12 mm; minimum thickness: 10.5 mm
• Height: 63.2 mm; torque spec: 103 Nm
• Intelligent marking location shows part number and minimum thickness
• Direct replacement design for rear brake service

Detailed Description

Brembo 08.A038.11 is engineered for rear brake applications that call for an OE-style solid rotor with precise dimensions and corrosion protection. The UV-coated finish helps shield exposed surfaces from rust, while the grey cast iron rotor body supports predictable pedal feel and reduced vibration in normal service. This makes it a practical choice for Lexus rear brake maintenance where fit, finish, and braking consistency matter.

Compatible With 2002-2010 Lexus SC430, rear; 1998-2005 Lexus GS300, rear; 2001-2005 Lexus GS430, rear; 2001-2005 Lexus IS300, rear; 1998-2000 Lexus GS400, rear; 1997-2000 Lexus LS400, rear with 4 piston caliper; and 2000 Lexus SC400, rear. This part cross-references Raybestos Brakes 96760 and PowerStop JBR739 for the same application.

For Lexus GS300 rear rotor replacement, Lexus IS300 rear brake service, or Lexus SC430 rear disc brake maintenance, Brembo 08.A038.11 provides the dimensions and coating needed for a direct-fit repair.

What It Helps Address

• Brake pulsation from worn or uneven rear rotors
• Surface rust on exposed rotor faces
• Noise and vibration associated with rotor wear
• Reduced braking consistency from rotors below minimum thickness
• Rear brake service needs on listed Lexus models

Installation Notes and Tips

Measure rotor thickness before installation and replace the rotor if it is at or below the minimum thickness specification. Brembo recommends replacing rotors and pads together to restore braking performance. Verify rear fitment, rotor dimensions, and the LS400 4 piston caliper note before installation. Follow the vehicle manufacturer’s torque specification during wheel installation and confirm the rotor seats cleanly on the hub.

Quality Assurance

Brembo develops this rotor as a direct replacement that meets or exceeds OEM specifications. The UV coating is solvent-free and intended to provide durable surface protection, while the intelligent marking location helps identify the part number and minimum thickness during service.
