A specialised brake wear gauge for use on heavy vehicles to check the thickness of remaining brake pad material.

An offset design allows for the blades to be inserted between the brake disc and the brake pad backing plate so that the pad thickness can be measured without the pad needing to be removed from the vehicle.

• 9 blades marked in both metric & imperial units. Range: 6 - 22mm (0.2362" - 0.8661").
• Always consult manufacturer's recommended measurements for brake pad replacement; many duty manufacturers recommend pad replacement at around 5mm.

Neon tubes glow to indicate if signal is present. Simply plug into spark leads then connect to high tension leads.

Checks spark to measure ignition voltage without removing spark plug. Simulates spark plug under compression load. For conventional and electric ignition systems.

Quickly locate faulty plug wires without piercing. Simply connect the inductive pick up onto the ignition lead. Light flashes indicating sound wire.
