Wagner Brake QC870 Disc Brake Pad Set - Front

Wagner ThermoQuiet QC870 Front Brake Pads

Wagner Brake ThermoQuiet QC870 disc brake pads are built for the front axle of select Lexus LS430 models. This ceramic brake pad set uses a zero-copper friction formulation, slotted pad faces, chamfered edges, and integrated shims to support quieter, more consistent braking performance.

Key Features

• Fits 2001-2006 Lexus LS430, front
• Ceramic friction material for everyday street use
• Zero-copper friction formulation
• Integrally Molded Insulator (IMI) technology for reduced brake noise
• Slotted design and chamfered edges
• Pad shims included
• Outer and inner friction material thickness: 0.626
• FMSI number: 7745-D870

ThermoQuiet Brake Pad Line

The Wagner ThermoQuiet line focuses on quieter operation and OE-style fitment. For the Lexus LS430 front brake application, the QC870 combines ceramic friction material with insulation-focused construction to help maintain smooth pedal feel and controlled stopping performance in normal driving conditions.

Detailed Description

The Wagner Brake QC870 is a front disc brake pad set for 2001-2006 Lexus LS430 models. It is engineered with ceramic friction material, slotted surfaces, chamfered edges, and pad shims to support stable braking and lower noise. The zero-copper formulation aligns with current friction material requirements, while the IMI technology helps isolate vibration at the pad backing for quieter operation. This part cross-references Raybestos Brakes PGD870C for the same application.

Common Brake Issues It Can Address

• Squealing or squeaking from worn front brake pads
• Brake vibration caused by uneven pad contact
• Reduced stopping performance from thin friction material
• Noise related to pad resonance during braking
• Brake service needs on a Lexus LS430 front axle

Installation Notes and Tips

Verify rotor condition, caliper movement, and pad fitment before installation. Clean the caliper bracket contact points and confirm the pad hardware surfaces are free of corrosion or debris. Because this application is front-position specific, confirm the vehicle is a 2001-2006 Lexus LS430 before ordering. The QC870 part number should be matched to the FMSI 7745-D870 profile during brake service.

Quality Assurance

Wagner Brake ThermoQuiet pads are built around a ceramic, low-copper friction design and IMI noise-control technology for OE-style braking performance on the Lexus LS430 front application.
