Lisle 28600 Disc Brake Piston Tool

The Lisle 28600 is a zinc-plated steel cube with a 3/8-in square drive socket on one face and multiple screw-in piston engagement profiles across the other faces · covering the single-pin, dual-pin, and triple-pin piston patterns found on domestic and some import rear disc calipers. It is a wind-back tool only: the job it does is rotating rear caliper pistons inward while compressing them, which is required on rear brakes with integrated parking brake mechanisms. Front disc brake pistons (push-in type) require a separate C-clamp or push-in tool; this cube does not address push-in pistons. No handle, no case, and no ratchet are included · the tool seats on a 3/8-in drive extension already in most home mechanics' toolsets. Owners broadly document reliable wind-back performance across a large install base for a tool priced under $15.

The right pick as a supplemental wind-back adapter when you already own a 3/8-in ratchet and need rear caliper screw-in coverage for domestic or common Japanese vehicles · the cube's face profiles handle the most common rear piston styles without a larger adapter kit purchase. Skip this if rear caliper compatibility for European vehicles (BMW, Mercedes, Audi) is needed, as vehicle-specific coverage for European dual-pin rear calipers is not confirmed in the listing or community data. Skip also if front disc brake service is the primary task · a C-clamp or push-in disc brake tool is necessary for push-in front pistons and the 28600 cannot substitute for it. For a complete single-tool brake kit with push-in and wind-back capability, a multi-adapter kit (such as the Astro Pneumatic 78618 or equivalent) is the better purchase.

Zinc-plated steel hand tool · no chemical exposure pathway in normal use. The cube body is all-metal with no plastic components, making it fully recyclable at scrap metal at end of life. Brake service work itself generates dust from friction material on pads and rotors; respiratory protection appropriate to the brake pad type and vehicle era is relevant to the work environment, not to this tool.
