Durable, precise disc brake alignment and piston-reset tool built for reliable workshop use Key benefits Prevents damage and deformation: smooth rims and cut grooves distribute pressure evenly during use, minimizing piston and caliper deformation for more consistent brake performance. Accurate alignment across common sizes: three engagement options (15 mm, 18 mm, 42 mm) let you set the correct angle and position for disc brake pistons and pads, improving repair efficiency and restoring proper brake friction. Protects finish and pistons: anti-scratch design helps reset pistons symmetrically and prevents one-sided protrusion, preserving caliper surfaces and pad seating while optimizing braking function using an SE healing. Comfortable, repeatable use: ergonomic handle reduces hand fatigue and gives secure control for precise adjustments during maintenance. Features and specifications Material: durable stainless steel for long-term, robust, resistant performance and consistent results. Engagement sizes: 15 mm, 18 mm and 42 mm options to fit a wide range of disc brake pistons and pad assemblies. Design details: smooth rims, cut grooves and anti-scratch contact surfaces that minimize slippage and component damage while ensuring even piston pressure. How it solves problems Replaces makeshift tools that can scratch or warp pistons and calipers. Speeds up brake service by providing immediate, correctly sized engagement points and stable alignment for piston resetting. Ensures symmetrical piston retraction to avoid uneven pad wear and braking pull. Typical applications Routine bicycle or motorcycle disc brake maintenance: reset pistons and realign pads after pad changes or fluid service. Workshop brake repairs: use during caliper servicing to ensure correct piston seating and consistent pad spacing. Field or mobile repair: compact, durable tool for quick on-site adjustments to restore safe braking feel. What makes it stand out Combines three common sizes in one stainless-steel tool with anti-scratch surfaces and an ergonomic handle for repeatable, professional-quality results.
