MAXGEAR 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.

Do you ship to my state?

Yes, we ship to all 50 U.S. states with tracked, insured shipping on every order.

Can I install this sensor myself?

Experienced DIY mechanics can typically install a wear sensor at home, especially during a brake pad replacement when the wheel is already off. If you’re not comfortable working on your brake system, we recommend having it installed by a qualified technician.

How long does shipping take?

Orders ship nationwide to all 50 U.S. states. Standard delivery typically takes 3–7 business days depending on your location; expedited options are available at checkout. Full details are on our shipping policy page.

What symptoms indicate a failed wear sensor?

Common symptoms include a wear warning light that stays illuminated despite adequate pad material, or no warning at all as pads wear thin — either points to a sensor that needs replacement.

Is this a direct OE replacement?

Yes. The MAXGEAR 20-0120 is engineered to match the connector type and mounting configuration of the original equipment sensor, so no modification is required for installation.
