Brake Caliper Piston Compressor 88mm Pad Spreader Tool

A brake caliper piston compressor used for pushing back quad pistons during brake pad changes and caliper servicing. Built around an 88mm maximum working range, it is suited to BMW, Mercedes-Benz and other vehicles using compatible quad piston calipers.

Used when replacing worn brake pads, fitting new pads or carrying out brake maintenance, this brake pad spreader tool helps create the space needed to refit the caliper over the disc and pads. It will suit garage work, workshop servicing and home vehicle maintenance where quad piston brake setups need the correct type of compressor rather than a basic single-piston tool. For anyone working on compatible performance or larger brake systems, it gives a more suitable way to reset the pistons before reassembly.

The tool is intended specifically for quad piston applications, which makes it more relevant for the job than a general-purpose brake spreader tool where access or piston layout can be awkward. The 88mm working range provides the reach needed across suitable calipers, helping with controlled piston retraction during brake work. That makes it useful for regular servicing where the right brake tool helps avoid struggling with improvised methods and can make pad replacement more straightforward. A dedicated tool like this is also easier to keep with brake service equipment so it is ready when the next pad change comes in.
