Product Details

Brembo’s Premium UV Coated OE Equivalent Rotor line focuses on direct replacement fitment and consistent braking feel. The 09.B634.11 uses grey cast iron and a vented design to support heat management in front brake applications. The UV coating helps protect the rotor surface, including the braking plate surfaces, while the marked minimum thickness and part number make inspection and service checks straightforward. This part cross-references PowerStop (e.g., JBR1395, JBR1395EVC) for the same application.

Common Brake Issues This Rotor Addresses

• Brake pulsation from worn or uneven rotor surfaces
• Noise and vibration during braking
• Corrosion on exposed rotor surfaces
• Reduced braking consistency from rotors below service thickness
• Front brake wear on Toyota 4Runner and Lexus GX460 applications
