Stay ahead of rear brake pad wear on your Lexus LS400 with the Standard Ignition Disc Brake Pad Wear Sensor PWS168. It installs as a direct-fit replacement for the rear brakes of the 1994-2000 Lexus LS400 (All engines), and these applications use two sensors, so plan on ordering a pair. A brake pad wear sensor is a small electrical device mounted at the pad; as the friction material wears to its minimum thickness, the sensor's circuit changes state and triggers the brake pad wear indicator on the dashboard, prompting service.
- Rear-position wear monitoring: designed to signal when the rear pads reach their wear limit so you know it's time to inspect the brakes.
- Direct-fit design: intended to install in place of the original rear wear sensor on the listed Lexus LS400 applications.
- Sold as needed for the axle: the listed applications use two sensors per vehicle; order two for a complete rear replacement.
If a worn or damaged wear sensor is the reason your brake pad wear light is on or not working correctly, this replaces it. Always diagnose the cause and inspect the pads before ordering, since the warning can also reflect genuinely worn friction material.
Manufacturer part number PWS168
Frequently Asked Questions
What vehicle does this sensor fit?
It's a direct-fit rear brake pad wear sensor for the 1994-2000 Lexus LS400 (All engines). The listed applications use two sensors per vehicle.
Is this a front or rear wear sensor?
The catalog lists this as a rear-position disc brake pad wear sensor for the 1994-2000 Lexus LS400.
How many do I need?
The listed Lexus LS400 applications use two rear wear sensors, so order two for a complete rear replacement.
What does a brake pad wear sensor do?
It's an electrical sensor at the pad; when the friction material wears to its limit, the circuit changes state and triggers the dashboard brake pad wear warning.
What are signs this sensor may need replacing?
A brake pad wear light that stays on, comes on incorrectly, or fails to illuminate may point to a worn or damaged sensor. Diagnose the cause and inspect the pads first.
