Buick Brake Pad

Choose Brake Pads by Vehicle, Axle and Brake Configuration

A brake pad set must match the vehicle's exact brake package and installation position. Begin with year, make, model, engine, trim, drivetrain, and any production or caliper note. Then confirm front, rear, or front-and-rear coverage, friction material, pad dimensions, wear-sensor provision, and included hardware. Brake pad replacement should follow the product fitment chart and vehicle service information; pads that share a general shape are not automatically interchangeable across different brake configurations.

Ceramic vs. Semi-Metallic Brake Pads

A ceramic brake pad uses a ceramic-based friction formulation, while a semi-metallic brake pad contains a substantial metallic component in its friction mix. Formulations can differ by manufacturer and application, so do not select material from a generic claim alone. The vehicle's approved application, driving demands, rotor compatibility, and the selected product's specifications take priority.

When both materials are listed for the same vehicle, compare the product-page information for noise-control features, dust behavior, operating characteristics, hardware, and intended use. Do not mix friction materials within one axle. If the site lists only one material for the exact configuration, use the listed application or obtain vehicle-specific guidance before substituting another formulation.

Front, Rear and Complete Brake Pad Sets

The catalog includes front-only sets, rear-only sets, and combined front-and-rear packages. Quantity alone does not identify coverage: verify the installation-position field and photos. Front and rear pads can use different shapes, thicknesses, slots, shims, sensor arrangements, and hardware even on the same vehicle.

• Brake package: Check trim, rotor size, caliper type, wheel size, production date, painted-caliper notes, and other listed restrictions.
• Wear sensor: Confirm whether the pad has an integrated sensor, a provision for one, or requires reuse or separate purchase.
• Hardware: Review whether clips, shims, lubricant, or other pieces are included; kit contents are SKU-specific.
• Dimensions: Compare pad shape, width, height, thickness, and interchange data where the listing provides them.

Brake Noise and Uneven Wear Require a System Inspection

Squealing, grinding, vibration, pulling, a longer stopping distance, a low brake pedal, or uneven pad wear can justify prompt brake inspection, but one symptom does not prove the pads are the only problem. Inspect the friction material and backing plates along with the brake rotors, caliper slides and pistons, brake calipers, hoses, fluid condition, wheel bearings, and mounting hardware as applicable.

A scored rotor, sticking caliper, contaminated surface, loose hardware, or installation error can create noise and irregular wear. Do not continue driving when braking response is unsafe or metal-to-metal contact is suspected. Arrange a qualified inspection and repair the root cause before fitting new pads.

Fitment and Installation Checks for Brake Pad Replacement

Before disassembly, confirm the product listing against the vehicle and inspect both sides of the axle. Follow vehicle service information for lifting, brake-service mode, caliper support, fastener settings, wear-sensor handling, and bedding or burnishing. Never allow a caliper to hang by its hose, and keep friction surfaces free of lubricant and contamination.

After installation, restore the pedal according to the service procedure before moving the vehicle. Check fluid level as directed, verify free wheel rotation, confirm sensor connections, and test braking response in a controlled setting. Reinspect if there is pulling, leakage, abnormal heat, noise, warning lamps, or a pedal that does not feel normal.
