Park Tool PS-1 Pad Spreader Piston and Brake Pad Separation Tool: The Indispensable Maintenance Companion for Your Hydraulic Brake System.

🔧 OVERVIEW: A PROFESSIONAL SOLUTION FOR EVERY CYCLIST'S WORKSHOP

The Park Tool PS-1 Pad Spreader is a must-have in the maintenance kit of every bicycle with hydraulic disc brakes. Simple yet revolutionary. It is a specialized tool. It solves frustrating and delicate problems such as brake pads accidentally sticking or pistons pushing back after replacement. strong, controlled and undamaged It is designed to solve this in a way. With its clever design that mimics "a part of the disk rotor," it is not just a spacer, but also a... It is a service vehicle.

⚙️ DESIGN ENGINEERING and MATERIAL QUALITY

• Materials and Structure:

  • Head Section: Made of durable stainless steel. High resistance to wear, corrosion, and bending. Does not deform even with continuous contact with brake pads and pistons.

  • Neck: Long, vinyl-dipped steel neck.

    • Length (162 mm / 6.4 inches): It operates on the lever principle. It allows you to apply maximum pressure in a controlled manner with minimum force.

    • Vinyl Coating: For manual use Prevents slipping, provides extra comfort and a firm grip. It allows you to handle cold metals directly without needing to touch them.

• Critical Design Detail: Rotor Simulation (1.95 mm Thickness)

  • The tip of the tool, 1.95 mm thick, very close to the thickness of a standard disk rotor (typically 1.8-2.0 mm). and is designed with a slightly conical shape.

  • What does this mean? The device, just like a real rotor, removes brake pads. It pushes evenly and parallel. This prevents one-sided or cross-jamming of the pistons, eliminating the risk of damaging the caliper's internal mechanism and delicate piston seals.

🛠️ PRACTICAL APPLICATIONS AND ADVANTAGES

1. SPREADING BRAKE PADS AND RESETTING PISTONS (Main Function)

• Scenario: After removing the wheel, the brake lever was accidentally squeezed. The pistons moved forward, causing the brake pads to stick together and the gap between them to narrow too much to accommodate the new rotor.

• Solution: PS-1's stainless steel tip fits between the two brake pads. in a controlled manner They are inserted. By gently rotating them using the long handle, the brake pads are separated from each other, and the pistons are positioned in the caliper housings. It is pushed back smoothly. The rim and rotor can be reattached.

2. REMOVING THE PISTONS DURING A NEW BRAKE PAD REPLACEMENT

• Scenario: The worn old brake pads were removed. To install the new, thicker pads, the pistons that had moved forward need to be pushed back.

• Solution: PS-1, by being inserted between the two clutch plates, pushes the pistons back simultaneously and evenly. It prevents interventions with ratchet wrenches, pliers, or other unsuitable tools that could damage the pistons/seals.

3. TEMPORARY TEST ELEMENT IN PLACE OF ROTOR (Unique Feature)

• Scenario: You want to test for air in the brake system, center the caliper, or check the feel of the brake lever. But constantly attaching and detaching the wheel and rotor is a hassle.

• Solution: PS-1, With its 1.95 mm tip, it mimics a rotor. By inserting this tool into the caliper, the brake lever can be squeezed and the system tested even when the wheel is not attached. This allows... enormously increases service and maintenance efficiency It is a professional trait.
