Specialised digital drum brake calipers to accurately measure drum brake wear. Suitable for vehicles with drum brakes up to 500mm in diameter.

For cars / SUVs, refer ET3565 which has a range of 0 - 300mm.

These calipers use an SR44 button battery which is not supplied with the unit. Designed for trade use only.

• 0 - 500mm
• Resolution: 0.01mm

Connects to any Power Probe. Limits output voltage to 5V. Essential for safely testing sensors and computer circuits on vehicles. Now you can supply a 5V reference signal to test computer modules, wiring and the components connected to them.

Measures up to 20A (and as low as 1 milliamp). Displays current in realtime. Adaptors work with all Power Probe circuit testers!

The PPPWM is an adapter that is plugged into Power Probe products with 4mm banana plugs (such as THE MAESTRO / PP4 / PP3 / PP3EZ etc).

The adapter can be set for the output 0-100% pulse width drive waveform by pressing the key. It is mainly used for automotive applications such as automotive fan circuit detection, to find the part of the circuit failure, in order to replace and repair.

Duty cycle adjustable 5% - 100%.

For 12V / 24V use. 10A max continuous output.

A metal body tool for accurately measuring brake disc thickness without needing to remove the wheel. Suitable for use on most motorcycles, cars and commercial vehicles.

• 0 - 45mm range
• Metric scale with 1mm graduations
• Spring action plunger, for quick operation

Accurately measure brake disc diameter without removing wheels. Quick identification of the brake system. Saves time!

• Suits most passenger / light commercial vehicles
• Range: 200 - 400mm
• Reach: 265mm

These colour coded gauges help identify brake lining that may require replacement. Quickly assess brake pad thickness on disk brakes, by inserting the blade between the brake disc and brake pad.

Traffic light like colour coding - Green / Go, Yellow / Caution, Red / Replace

• Colour coded metal gauges
• Measuring range: 2mm - 12mm

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.

Quickly / simply measure trending brake thickness without removing any components.

Place the end of this lightweight gauge against the brake disc surface; slide back the measuring peg until it stops against the back plate of the brake pad. Read off the thickness of the pad material in mm.

• Colour coded green | yellow | red traffic-light symbol as to whether you need to replace the brake pads.
• Made from lightweight aluminium.

An updated / improved version of traditional brake rotor gauge kits.

This model uses a clamping system for universal application. On late model vehicles, the clamp points are not necessarily ferrous metal, meaning that traditional magnetic clamping fixtures are no longer suitable.

Ideal for checking tyre / wheel run-out. And also measuring the brake disc / brake hub.

• Measuring range: 0-10mm
• Graduations: 0.01mm
• Aluminium clamping range: 20 - 100mm
