Common Brake Issues Addressed

• Brake squeal during light or moderate stops
• Uneven pad wear on front disc brake service
• Reduced braking consistency from worn friction material
• Brake warning from a worn mechanical pad sensor
• Noise and vibration associated with aged front pads

Installation Notes

Verify rotor condition, caliper operation, and pad fitment before installation. Clean the caliper bracket contact points and confirm the pad wear sensor routes correctly for the vehicle application. Because this is a front disc brake pad set, install only on the listed front position applications for the confirmed Lexus and Toyota fitments.
