OTC 6596 Brake Pad Gauge

OTC's Brake Pad Gauge allows for a definitive measurement of brake pads to determine remaining life. Unique design allows for measurement on the vehicle without the removal of any components in most cases (wheel assembly or brake caliper). Quick, easy verification of brake pad condition via color code scale - Red means No, Green means Go. Crafted from rugged materials to ensure long term performance and durability. To calibrate: when probe tip is in locked position (resting on either body ledge), barrel measurement should be 4mm - adjust set screw and end screw as necessary to achieve 4mm measurement
