The rear brake pad wear sensor monitors the thickness of the brake pad friction material. When the pad wears down to a predetermined limit, the sensor alerts the vehicle’s onboard systems (and driver) via a dashboard indicator, helping prevent damage to the braking system and maintaining safety.
Function:
• Detects rear brake pad wear
• Signals brake wear status to the dashboard
• Helps avoid excessive pad wear or rotor scoring
• Supports timely and safe brake maintenance
Driving with worn brake pads without proper indication can lead to:
• Reduced braking performance
• Longer stopping distances
• Scored or damaged rotors
• Risk of brake system component failure.
A functioning brake pad wear sensor helps maintain optimal brake performance and prevents unnecessary damage to expensive brake components.
When to replace:
• Rear brake wear warning light illuminates
• During rear brake pad replacement
• If sensor wire, connector, or clip is damaged
• When replacing rotors or servicing rear brake hardware.

High-quality OE Match replacement rear brake pad wear sensor, engineered to match original Porsche specifications for monitoring rear brake pad wear. Designed for Porsche 997 models, this sensor works with the vehicle’s onboard diagnostic system to provide timely alerts when the rear brake pads approach the service limit.
Sold individually, typically 2 sensors per axle for complete rear pad sets
Fits:

Porsche 997.2 C2 2009 - 2012 Rear Caliper
Porsche 997.2 C4 / C4S 2009 - 2012 Rear Caliper
Porsche 997 TT / GT2 2007 - 2013 Rear Caliper
Porsche 997 GT3 2007 - 2013 Rear Caliper
The rear brake pad wear sensor detects when the brake pad material has worn to its minimum safe thickness and signals the vehicle’s warning system. This alert enables brake servicing before the pads cause damage to other braking components.
Function:
• Monitors rear brake pad wear
• Interfaces with the vehicle’s onboard warning system
• Helps prevent brake rotor damage from worn pads
Brake pads naturally wear down with use. A functioning brake pad wear sensor ensures you receive timely alerts before the pads reach critically low levels. Without a reliable sensor, pad wear may go unnoticed, leading to reduced braking performance, rotor damage, and safety concerns - especially on performance-oriented vehicles like the 997.
When to replace:
• Brake wear warning light appears
• Sensor wiring or connector is damaged or corroded
• After rear brake pad replacement
• During routine brake system servicing
• When upgrading brake components
