PowerStop SW-1904 Disc Brake Pad Wear Sensor - Rear

Rear Brake Wear Sensor Overview

This PowerStop rear disc brake pad wear sensor is built for Mitsubishi Fuso applications that use an electronic wear indicator. It matches the original form, fit, and function expected from an OEM-style replacement, with a design focused on reliable conductivity and long service life.

Part number SW-1904 is a practical replacement for worn or damaged brake wear sensors on compatible Mitsubishi Fuso FE-series trucks. The PowerStop Euro-Stop line emphasizes straightforward replacement parts for brake service, and SW-1904 follows that approach with a fitment-specific design.

Key Features

• OE-style replacement for electronic brake pad wear monitoring
• Built to meet or exceed OEM requirements
• Engineered for high-temperature resistance and stable conductivity
• Black oval connector with female terminal design
• Includes a 2-wire harness with integrated grommets

Detailed Description

SW-1904 is a rear disc brake pad wear sensor from PowerStop’s Euro-Stop line, made for vehicles that rely on an electronic warning circuit to track pad wear. It is designed to match the original sensor’s form, fit, and function, making it a direct replacement choice for service work on Mitsubishi Fuso FE145, FE145CC, FE180, FE140, and FE120 rear brake applications. The sensor uses a black oval connector, blade terminals, and a 2-wire layout with three grommets included in the assembly.

PowerStop builds this sensor to handle extreme temperatures while maintaining electrode conductivity over time. That matters in brake systems where consistent signal transfer is needed to keep the wear indicator functioning properly. Part number SW-1904 is also cross-referenced to Centric Parts 116.74005 and Raybestos Brakes WK1390 for the same application.

What It Helps Address

• Brake wear warning light staying on after pad service
• Damaged or brittle sensor wiring
• Faulty connector or terminal connection at the brake wear circuit
• Loss of wear-indicator signal from heat or age
• Sensor replacement during rear brake maintenance

Installation Notes and Tips

Verify connector shape, terminal style, and rear fitment before installation. Replace the worn sensor during brake service so the warning system can operate correctly after pad replacement. Confirm the vehicle uses the listed rear application for Mitsubishi Fuso FE145, FE145CC, FE180, FE140, or FE120 before ordering SW-1904.

Quality Assurance

PowerStop states that this Euro-Stop brake wear sensor is engineered to meet or exceed OEM requirements and is built for long-term operation under high-temperature conditions.
