Disc Brake Pad Spreader by Park Tool - PS-1

Allows you to get between the brake pads on hydraulic brake systems to allow you to push the pistons back into the caliber - when servicing / repairing or just changing brake pads

• A great tool for any rider or mechanic who services hydraulic brakes
• The PS-1 Pad Spreader features a tapered edge designed to drive apart and reset hydraulic bicycle brake pads that may have been accidentally engaged
• The head of the PS-1 mimics a section of disc brake rotor
• Strong stainless steel construction
• Long, vinyl-dipped handle for leverage and comfort

The PS-1 can also be used as a temporary stand-in for the rotor when testing or servicing the hydraulic system, negating the need to repeatedly remove and install the wheel
