Brake pad wear sensor. Porsche 928 1989-95 ❭ 92861236301
- Porsche 928S4 5.0L 1987-92
- Porsche 928GT 5.0L 1989-91
- Porsche 928GTS 5.4L 1992-95
The OE Match Rear Brake Pad Wear Sensor is a high-quality replacement braking system component designed to monitor the condition of the rear brake pads and alert the driver when the friction material reaches its minimum safe operating thickness. Manufactured to OE specifications for fit, function and reliability, this sensor helps ensure timely brake maintenance and supports safe braking performance.

Fits:
- Porsche 928S4 5.0L 1989-92
- Porsche 928GT 5.0L 1989-91
- Porsche 928GTS 5.4L 1992-95
Installed directly into the rear brake pad assembly, the sensor continuously monitors brake pad wear and communicates with the vehicle's brake warning system. When the brake pads wear down to a predetermined limit, the sensor activates the dashboard brake wear warning light, notifying the driver that rear brake pad replacement is required.
What This Product Does:
- Monitors rear brake pad wear throughout the service life of the brake pads.
- Activates the brake wear warning indicator when replacement is required.
- Provides early warning of rear brake maintenance needs.
- Helps prevent excessive brake pad wear.
- Protects brake discs from damage caused by worn brake pads.
- Supports safe and effective braking performance.
- Assists with preventative brake system maintenance.
Symptoms Of Wear Or Failure:
- Brake wear warning light remaining illuminated.
- Intermittent brake wear warning messages.
- False brake wear alerts despite adequate brake pad thickness.
- No warning light when brake pads are excessively worn.
- Damaged, broken or frayed sensor wiring.
- Corrosion or physical damage to the sensor body.
- Brake monitoring fault codes stored within the vehicle system.
- Warning light remaining active after brake pad replacement.
Why Replacement Matters:
- Rear brake pad wear sensors operate in demanding conditions and are exposed to heat, brake dust, moisture, road debris and constant vibration. In many applications, the sensor is designed to wear alongside the brake pads and should be replaced whenever new rear brake pads are installed to ensure continued monitoring accuracy.
- A damaged or malfunctioning sensor can provide inaccurate brake wear information, potentially resulting in unnecessary warning lights or failure to alert the driver when brake pads require replacement. If brake pads wear beyond their service limit, braking performance can be reduced and costly damage to the brake discs may occur.
- Replacing a worn rear brake pad wear sensor restores accurate brake wear monitoring, ensures proper operation of the dashboard warning system and helps maintain safe braking performance. An OE Match replacement provides factory-style fitment, dependable operation and long-term reliability, making it an essential component during rear brake servicing and maintenance.

Brake pad wear sensor – Porsche 911 1984–89 99361296502 by OEMatch for selected Porsche 911 3.2L models from 1984–1989, including G50 applications. This replacement sensor supports the brake pad wear warning circuit and is intended to match the supplied Porsche reference for correct form, fit and function.
What This Product Does
A brake pad wear sensor is an electrical service component positioned at the brake assembly to indicate pad wear through the vehicle warning system. Many owners search for genuine or OEM alternatives; OEMatch supplies direct-fit replacements designed to match the original form, fit and function for Porsche applications.
Functions
- Monitors brake pad wear at the fitted brake position.
- Supports the brake wear warning circuit.
- Helps identify when pad replacement or brake inspection may be required.
- Can be renewed during pad replacement or wider brake service work.
- Matches Porsche reference 99361296502 where this number is specified for the vehicle.
Symptoms of Fault
- Brake wear warning message or warning lamp remains active after pad replacement.
- Damaged sensor cable near the caliper area.
- Broken retaining clip or poor location around the brake assembly.
- Intermittent brake wear warning caused by a worn or damaged sensor.
- Repeat warning issues where the wrong sensor variant has been fitted.
Why Replacement Matters
Brake pad wear sensors are commonly replaced when brake pads are changed, especially if the existing sensor has worn through, broken during removal, or triggered the warning circuit. Selecting the correct OEMatch sensor helps maintain the intended warning function and reduces the risk of repeat work caused by damaged wiring or incorrect fitment.
