Product Information
Brake pad wear sensor, Rear.
It’s a factory-engineered electrical brake pad wear sensor cable that monitors pad thickness and helps alert the driver when brake pads are nearing the end of their service life.
Sold each, 2 required per car

Fits:
Porsche 9YA Cayenne / Cayenne Coupe 2018>>
* For cars with option codes:
  1KX - Rear disc brakes - disc diameter 18 inches, Brake calliper painted Silver
  1KS - Rear disc brakes, 18", green
  1KU - Rear brake discs, Disc diameter 19", Black brake callipers,
  2EN - Rear brake discs, disc diameter 19-inches, Brake callipers, Red
  2EI- Rear brake discs, disc diameter 18 inches, brake calliper painted Black

This brake pad wear sensor acts as a wear monitoring device within the brake system. When brake pads wear down to a critical thickness, the sensor contacts the brake rotor or closes its circuit, triggering a warning light in the vehicle’s instrument cluster. This alerts the driver that it’s time for pad replacement — helping maintain safe braking performance and avoiding damage to rotors or other brake components.

Product Information
Brake pad wear sensor, Rear.
The rear brake pad wear sensor detects the remaining thickness of the brake pad friction material and signals the vehicle’s service reminder system when the pads need replacement. It helps drivers schedule brake service before pads reach critically low levels.
Sold each, 2 required per car

Fits:
Porsche 9YA Cayenne / Cayenne Coupe - 2018 to 2023
* For cars with option codes: 
  1KX - Rear disc brakes - disc diameter 18 inches, Brake calliper painted Silver
  1KS - Rear disc brakes, 18", green
  1KU - Rear brake discs, Disc diameter 19", Black brake callipers,
  2EN - Rear brake discs, disc diameter 19-inches, Brake callipers, Red
  2EI - Rear brake discs, disc diameter 18 inches, brake calliper painted Black

This OE Match rear brake pad wear sensor is engineered to meet OE-equivalent standards for electrical resistance, connector fit, and mounting geometry. It functions as a simple yet critical safety sensor: when the brake pad friction material wears down to the sensor level, it completes (or breaks) an electrical circuit that triggers a warning in the dashboard display.

Brake pad wear sensors protect your vehicle by providing an early notice that pad material has reached a minimum safe thickness. Without a functioning sensor, pads may wear excessively before being noticed - possibly leading to rotor damage, reduced braking performance, and higher repair costs.

This OE Match sensor installs directly into the brake caliper/lining assembly at the rear axle, using the original connection harness and clips. It’s ideal for brake servicing, pad replacement intervals, or when upgrading to OE-equivalent replacement pads.

Brake pad wear sensors are a key safety component: they help prevent unexpected brake failure, excessive rotor wear, and costly repairs by giving you an early warning that pads need service. Replacing a worn or broken sensor with an OE Match brake pad wear sensor ensures the vehicle’s warning system functions correctly and helps maintain proper brake maintenance intervals.

When to replace:
•  Brake wear warning illuminates on the dashboard
•  After replacing rear brake pads
•  Sensor is damaged or corrosion present
•  During brake system overhaul or service
•  If the connector or wiring shows wear or damage

About Brake Pad Wear Sensors

Porsche Brake Pad Anti-Wear Sensors | Design911 Precision Components for Safety, Monitoring & Maintenance

Brake pad anti-wear sensors play a vital role in your Porsche’s braking system by monitoring pad thickness and alerting you when replacement is needed. By providing real-time data, these sensors help prevent excessive wear, protect brake discs, and maintain braking safety. Replacing worn or damaged sensors ensures your Porsche’s onboard systems can accurately detect pad wear — preserving both performance and peace of mind.

At Design911, we supply a comprehensive range of brake pad anti-wear sensors designed for precise fitment and dependable performance. Manufactured using high-grade materials and advanced sensor technology, our components ensure accurate readings under all driving conditions. Ideal for routine maintenance, restoration, or brake system upgrades, these sensors help your Porsche maintain its legendary braking precision.

What Do Brake Pad Anti-Wear Sensors Do?

Brake pad wear sensors are an essential electronic component that monitor the condition of your brake pads and alert the driver when they need replacement.

Core Functions:
• Continuously monitor brake pad thickness.
• Trigger dashboard warning lights when pads reach the wear limit.
• Protect brake discs from damage caused by worn pads.
• Support preventative maintenance and consistent braking performance.
• Ensure optimal braking efficiency and driver safety.

Accurate brake pad sensors allow you to maintain Porsche’s high standards of safety, performance, and responsiveness.

Why Do Brake Pad Anti-Wear Sensors Fail or Degrade?

Because they operate in extreme environments near the wheels and brakes, wear sensors are exposed to heat, friction, and contamination, which can cause malfunction or damage over time.

Common Causes of Failure Include:
• Melting or cracking due to high brake temperatures.
• Corrosion or electrical failure from water and road salt.
• Cable wear or fraying caused by vibration or debris.
• Poor connections or sensor dislodgement during servicing.
• Age-related degradation of wiring or insulation.

When a sensor fails, the system may provide false warnings or fail to detect worn pads, increasing the risk of brake system damage or reduced safety.

Why Replace or Upgrade Your Porsche Brake Pad Anti-Wear Sensors?

Replacing faulty or aged sensors ensures your Porsche’s braking system continues to deliver accurate monitoring and performance reliability. Design911’s precision-engineered sensors are crafted for long-term durability and compatibility across Porsche models.

Key Benefits:
• Restores accurate brake pad wear monitoring.
• Prevents unnecessary pad or disc wear.
• Heat- and moisture-resistant design for long-lasting reliability.
• Plug-and-play fitment for easy installation.
• Engineered for exact Porsche compatibility.
• Ideal for maintenance, upgrades, or complete brake servicing.

Design911’s Porsche brake pad anti-wear sensors ensure consistent safety alerts and reliable performance — maintaining the precision and quality expected of every Porsche braking system.

Highlights

• Premium Porsche brake pad wear sensors for accurate monitoring.
• Designed to withstand extreme heat and vibration.
• Ensures timely replacement of brake pads for safety.
