ZTTO Hydraulic Disc Brake 2 & 4 Piston Reset Tool
Professional Brake Maintenance Solution for All Riders

ZTTO's Hydraulic Disc Brake Piston Reset Tool is designed to deliver an efficient, safe, and scratch-free way to reset both 2-piston and 4-piston hydraulic brake calipers. Each set includes two high-strength engineer-grade nylon tools, tailored for modern bicycle maintenance. Whether you're a seasoned bike mechanic or a weekend warrior, this tool helps you maintain your braking system with professional-level precision.

Durable & Fluid-Resistant Materials

Made from high-grade oil-resistant nylon, the tool ensures it won't degrade or swell when exposed to brake fluid. It's engineered to eliminate the risk of scratching or gouging your brake pistons – a safer alternative to metal tools.

Dual-Duty Versatility

Each tool is designed for multiple functions. Use both together to evenly reset pistons after removing pads, or use one tool solo as a pad spacer without removing the brake pads. The added function as a mini lever bar brings more convenience to your maintenance routine.

Comfort-Driven Ergonomics

With an 80mm extended handle and a 100mm widened grip pad, this tool minimizes hand fatigue during piston resets. You get excellent leverage and pressure distribution, so you can push firmly without hurting your palms.
