Feature: 1. Ease To Use: The disk brake rotor gauge features a unique design that allows for secure mounting of a dial indicator directly onto the brake disc, facilitating accurate measurement of brake rotor warp. Its innovative construction enables you to firmly attach the dial indicator in virtually any position, enhancing convenience during inspections. 2. Accurate Measurement Capabilities: With a measuring range of 0-1in and a resolution of up to 0.001in, the integrated dial indicator provides highly accurate and good readings. This accuracy helps you effectively assess brake pad wear, thereby allowing for more informed maintenance decisions and avoiding unnecessary replacements due to inaccurate measurements. 3. Versatile 360° Flexibility: The disc brake rotor gauge set includes a 360° flexible arm support, allowing measurements from a variety of angles, including horizontal, vertical, and inclined positions. You can easily adjust the arm's position and angle as needed, making the measurement process smoother and more efficient, regardless of the job at hand. 4. Secure Locking Mechanism: Equipped with a 7 inch tight lock clamp, the disc brake rotor gauge dial Indicator ensures firm attachment to the components being measured, minimizing external interference and unnecessary movements. The clamp's good grip enhances measurement accuracy by keeping the dial indicator stable during assessments. 5. Enhanced Safety: By utilizing the brake rotor and ball joint gauge set, you can effectively check for tire and wheel runout, gear backlash, and valve guide wear. Performing these checks promotes safer driving conditions, improving vehicle performance and longevity while providing you with peace of mind on the road.
