The 5000 Advanced pad line is formulated for stable friction performance and consistent pedal feel across a range of driving conditions.

What This Brake Kit Helps Address

• Front brake noise from worn pads or fatigued hardware
• Uneven rotor wear or rotor surface corrosion
• Reduced stopping performance from aged friction material
• Brake vibration caused by worn or out-of-spec components
• Extended service time when replacing rotors, pads, and hardware together
