Caliper AWTools AW18811BL — set of 11 pieces, total weight 1.73 kg

AWTools AW18811BL caliper set comprising 11 pieces and total weight 1.73 kg is a portable toolkit for measuring internal and external clearances and depths in automotive brake service and general workshop tasks. The tools are made of solid carbon steel with a rust-resistant blasted finish, supplied in a plastic case for safe storage and transport. This set includes disc brake hand-held calipers designed to assist when servicing both push-in (front) and screw-in (rear) brake pistons and is compatible with the majority of vehicle makes.

Advantages

The calipers are manufactured from solid carbon steel with a rust-proof blasted finish that improves durability and resists corrosion in workshop environments. The set contains multiple pieces to enable repeatable mechanical measurements across different jobs, while the compact plastic case keeps the tools organized and protected during transport. The design is suitable for both push-in and screw-in brake applications, reducing the need to switch between separate dedicated tools.

Suitable for

• Measuring internal and external brake piston clearances
• Checking depths and gaps during brake servicing and maintenance
• Workshop, repair and production environments requiring repeatable mechanical measurements
• Mobile technicians and service vans that need compact, transportable tools

Key specifications

• Set composition: 11 pieces calibrated for internal/external and depth measurements
• Total weight: 1.73 kg (including plastic case)
• Material: solid carbon steel with rust-resistant blasted finish
• Application: hand-held disc brake calipers for push-in and screw-in brake pistons
• Storage: compact plastic carrying case for transport and protection

How to use

Select the appropriate caliper from the set for the required measurement task, open the caliper jaws and position them on the internal or external surface or depth to be measured. Close the jaws gently until they contact the measured surface and read the value according to the caliper’s scale or transfer the measurement to the required gauge or service specification. When servicing disc brakes, choose the tool suited for push-in (front) or screw-in (rear) piston types and follow vehicle manufacturer procedures for brake retraction and piston alignment. After use, clean off debris and store the tools in the supplied plastic case to maintain accuracy and prevent corrosion.

Usage recommendations

Use the calipers in clean, dry conditions and avoid exposing the tools to harsh chemicals. Verify measurements against manufacturer service limits and periodically inspect the calipers for wear or damage. Store the set in the plastic case when not in use to preserve the rust-resistant finish and ensure consistent measurement performance.
