Unior Disc Brake Piston Spreader – Bulk Pack
A must-have tool for servicing hydraulic disc brakes. The Unior Disc Brake Piston Spreader is designed to safely and evenly reset brake pistons after the pads have been advanced.
Whether it’s accidental lever pulls without a rotor installed or routine brake service, this tool helps restore proper caliper spacing quickly and cleanly.
Why You Need It
If brake pistons are pushed out too far, reinstalling the wheel or rotor can become difficult. Forcing pads apart with makeshift tools risks damaging pistons or pad surfaces.
This spreader is specifically shaped to slide between pads and fully retract pistons evenly and safely.
