Accurate Measurement: The brake disc depth caliper is a high-quality measuring tool for accurately measuring disc brake thickness and tire tread depth to ensure optimum vehicle performance Readings Easy to Use: The brake disc depth measuring ruler features a unique floating jaw arrangement with leverage, ensuring easy removal of the brake disc while maintaining the measured value. Thus, the brake disc measuring tool is extremely convenient to use, even for people with limited mechanical experience Aluminum Alloy Material: Made of high-strength aluminum alloy, this metric caliper is designed to measure brake disc depth for a long service life. The compact size of the disc brake rotor caliper also allows for convenient storage. Do not use High Precision Gauge: The vernier caliper micrometer is designed for a measuring range of 0-60mm, with 0.1mm increments, it provides extremely reliable and accurate readings, a portable tire tread depth gauge gives mechanics the precision they need to get the job done right Practical Tool: In addition to measuring the thickness of the brake disc, this caliper also provides a simple and effective method to check the depth of the tire tread. The tire tread depth gauge can help ensure driving safety. The brake disc caliper with metric scale is a practical and useful tool. Any professional mechanic or DIY enthusiast should include it in their toolbox
