Digital Caliper for brake components Durable stainless steel construction: designed to last longer than calipers with plastic or carbon fiber parts, for reliable measurement of brake pad thickness and brake disc thickness. Precise measurement range and function: measures from 0 to 150 mm with a digital display. Calipers glide smoothly thanks to precision rollers and locking screws, and you can reset to zero with the button to start a measurement at any point on the scale, ideal for differential measurements. Large splashproof LCD display: easy to read results quickly. The display opens automatically when you slide the guide rail, and the unit powers off automatically after 1 minute of inactivity to save battery. Easy to use in tight spaces: clear, easytoread measurements on an ergonomic design that fits comfortably in the hand and reaches hardtoaccess areas around the vehicle. The zero button allows rezeroing during measurement for added flexibility. Practical applications: Routine brake service: check brake pad thickness and disc wear to determine replacement timing. Differential wear checks: compare wear between two components by resetting zero at a reference point and measuring differences along the scale. Work in confined spaces: measure brake components around calipers and wheel assemblies without removing components.
