PowerStop SW-1229 Disc Brake Pad Wear Sensor - Front or Rear

Front Brake Wear Sensor for OE-Style Monitoring

PowerStop SW-1229 is a front electronic brake wear sensor built for vehicles that rely on pad wear monitoring to alert the driver before brake material is fully consumed. It is designed to match original equipment form, fit, and function while using temperature-resistant construction for stable conductivity over long service life.

Compatible With 2024-2025 Buick Enclave, front; 2024-2025 Chevrolet Traverse, front; and 2024-2025 GMC Acadia, front. This part number, SW-1229, is also listed for 2026 Buick Enclave, rear; 2026 Chevrolet Traverse, rear; 2026 GMC Acadia, rear; and 2025 Cadillac OPTIQ, rear.

Key Features

• Electronic disc brake pad wear sensor for front brake applications
• OE-style form, fit, and function for direct replacement use
• Built to withstand extreme temperatures for consistent electrode conductivity
• Black connector with oval shape and female connector gender
• Blade terminals with 2-wire construction and 1 connector
• Includes grommet for secure routing and retention
• Wiring harness length: 11.42 in. (290 mm)

Product Details

PowerStop’s Front Electronic Brake Wear Sensor line focuses on restoring the brake pad wear monitoring system after pad and rotor service. SW-1229 is engineered to meet or exceed OEM requirements for form and function, helping maintain the warning strategy used on modern brake systems. For drivers servicing a Buick Enclave, Chevrolet Traverse, or GMC Acadia, this sensor supports accurate wear detection without changing the original system layout.

This part cross-references Monroe Shocks & Struts (e.g., 347-47012, 26473210) for the same application.

What It Helps Address

• Brake wear warning light staying on after pad replacement
• Damaged or brittle wear sensor during brake service
• Inaccurate pad wear monitoring from an aged sensor
• Connector or terminal wear at the brake sensor lead
• Service interruptions caused by a failed electronic pad wear sensor

Installation Notes and Tips

Replace the wear sensor when servicing brake pads if the original sensor is worn, damaged, or has triggered a warning. Verify connector shape, terminal style, and harness routing before installation. On vehicles such as the 2024-2025 Buick Enclave, 2024-2025 Chevrolet Traverse, and 2024-2025 GMC Acadia, confirm front-position application details against the vehicle’s brake system before final assembly.

Quality Assurance

PowerStop builds this sensor to meet OE-style requirements and to maintain conductivity under high-temperature brake conditions. The design focus is long-term signal reliability after extended mileage, supporting the brake system’s original wear-monitoring function.
