It’s often the smallest parts of a vehicle that make the biggest difference to safety, and brake wear sensors are a perfect example. The Jaltest Wear Sensor Tester (WST) is a compact, powerful tool that’s revolutionising how quickly and accurately workshops can check wear sensors on brake pads.
In this article, we take a closer look at this tool and highlight how it can help to lower your workshop costs and improve diagnostic efficiency.
What Is the Jaltest WST, and Why Do You Need It?
The Jaltest WST is a portable device specifically designed to check and adjust brake pad wear sensors for commercial vehicles, buses, trailers, and more. You can connect directly to the sensor, select the sensor type via a built-in selector, and read the voltage output to determine brake pad wear — all without dismantling the brake assembly.
This isn’t just a time-saver; it’s a game-changer for diagnostic precision and workflow efficiency.
What It Does: Features & Functionality
The Jaltest WST packs several smart features into a rugged, handheld device:
- Fast, non-invasive checks — Connect right to the sensor and skip the component disassembly.
- Dual-sensor compatibility — Whether it’s a 2-wire/end-of-pad sensor or a continuous wear sensor, the WST covers both.
- Sensor-selector dial — Choose the correct sensor type quickly using the integrated selector switch.
- Voltage reading display — View the voltage (in volts) directly to assess wear percentage.
- LED indicators — Clear green/red LEDs show whether brake pad wear is within acceptable limits.
Eclipse Automotive Technology - Compact, user-friendly design — Lightweight (approx. 193 g) and sized to fit even busy workshop environments.
Key Benefits
Save Time & Reduce Downtime
No need to dismantle brake components. Just plug in, select, and get results fast—keeping vehicles on the road longer.
Accurate Diagnostics = Better Decisions
With real-time voltage data and clear visual alerts, you’ll know exactly if, when, and how to service those pads.
Extend Brake Pad Life
By aligning sensor readings to precise thresholds, the WST gives you the insight needed to avoid premature replacements—saving in parts and labour.
Improved Safety & Compliance
Avoid the risk of brake pad failure and ensure maintenance adheres to safety standards. Faulty sensors equal blind spots; the WST keeps you clear.
Versatility Across Makes & Models
Whether your fleet includes Volvo, DAF, Iveco, Mercedes-Benz, MAN, Scania, Knorr-Bremse, Wabco, Renault, or others—the WST supports numerous sensor systems via its clever selector and connector kit.
