A.B.S. 39590 Brake Pad Wear Sensor

A brake pad wear warning light that won’t turn off — or one that never comes on — often points to a failed wear sensor rather than the pads themselves. The A.B.S. 39590 warning contact restores accurate pad wear monitoring, engineered as a direct OE-fit replacement.

Key Benefits

The A.B.S. 39590 warning contact is manufactured to restore accurate pad wear monitoring. Here’s what this replacement part offers:

• Straightforward installation using factory mounting points and connector types.
• A.B.S. manufacturing standards, backed by a standard parts warranty against defects in material and workmanship.
• OE-matching fitment designed to connect directly to your vehicle’s existing wiring harness with no modification.
• Early warning protection that helps prevent costly rotor damage from pads worn down to metal-on-metal contact.
• Accurate wear detection engineered to A.B.S. 39590’s original electrical and mechanical specifications.
• Durable construction designed to withstand brake dust, heat, and moisture exposure over time.

Product Specifications

Every A.B.S. 39590 warning contact is manufactured to match OE electrical and dimensional specifications. Full technical details are listed below; always verify fitment against your vehicle’s VIN before ordering.

A.B.S. is an aftermarket brand focused on precision-engineered brake sensor and hardware components manufactured to strict quality-control standards.

Use Cases and Applications

This warning contact is suited for addressing a stuck or malfunctioning brake wear warning light, replacing a sensor during pad service, and restoring accurate pad wear monitoring. Typical scenarios where drivers choose this part include:

• Replacing a sensor after the wear warning light stays on despite adequate remaining pad material.
• Restoring warning functionality after a sensor fails to alert at the expected wear point.
• Installing a new sensor alongside a brake pad replacement, as many manufacturers recommend.
• Addressing a sensor damaged during a previous brake service.

Because wear sensors are manufactured for a specific electrical connector and mounting configuration, this part is intended as a direct match for the applications it’s designed for — always confirm fitment against your vehicle’s OE part number before ordering. Keeping this sensor in good working order helps protect your rotors from the accelerated wear and damage that comes from driving on pads that are worn past their service life.
