- brake piston reset tool is designed to speed up brake pad replacement on cars, trucks or vehicles with four-wheel disc brakes by squeezing the inner lining and resetting the piston. When installing new brake shoes and pads, it fully pushes back the brake caliper piston, allows pad replacement, and then returns the piston to the caliper. This process helps prevent damage to the piston surface and provides smooth, gentle operation. - High quality material: forged, high-hardness alloy construction for strength and toughness. The chrome-plated top is resistant to rust, and the thickened top resists deformation. The distance between the adapter plate and the center of the bolt shaft is about 22 mm to 32 mm, making the tool suitable for most disc brake calipers. The kit includes the piston reset tools and is compatible with domestic and import vehicles equipped with right-hand thread pistons. - compact design: the tool offers precise, stable performance for resetting pistons. Its innovative design provides a smooth and even piston reset, reduces unnecessary shaking and jamming, and helps protect brake system components. - easy to use: the reset tool features a simple design with retractable pistons on both left and right brake caliper sides and threaded components for reliable operation. Even beginners can complete the brake piston reset with the screws and adapter plate included in the kit. - compatibility and scope: suitable for most disc brake calipers on vehicles with right-hand thread pistons. compatible with cars, trucks and other vehicles that use four-wheel disc brake systems. - use scenarios: - performing a brake pad replacement on a sedan or SUV with four-wheel disc brakes, ensuring the piston is reset without damage. - servicing rear or front disc brakes on trucks where precise piston retraction is required before new pads are installed. - in a workshop or home garage setting, performing brake maintenance on multiple vehicles without risking piston surface damage or uneven pad seating. - included items and attributes: high-quality alloy piston reset tool set with chrome-plated top, thickened top design, and an adapter plate. distance from adapter plate to bolt shaft center is 22–32 mm, compatible with most disc brake calipers. includes piston reset tools for immediate use on right-hand thread piston vehicles.
