Product Components
The Orion Motor Tech 24-Piece Brake Caliper Compression Tool Set includes the following components, neatly organized in a durable blue storage case:
- 18 x Piston Adapters (various sizes and pin configurations)
- 2 x Thrust Bolt Assemblies (one right-hand threaded, one left-hand threaded)
- 2 x Retainer Plates
- 2 x Brake Caliper Hangers
- 1 x Pair of Work Gloves
- 1 x Storage Case
- 1 x Instructions Manual


Setup
Before beginning any brake service, ensure the vehicle is safely lifted and supported on jack stands. Remove the wheel and the brake caliper according to your vehicle's service manual. Prepare the new brake pads for installation.
Follow these steps to set up the brake caliper compression tool:
- Step 1: Select the appropriate adapter from the 18 provided pieces that matches the piston face of your vehicle's brake caliper. Refer to the compatibility chart in the Operating Instructions section for guidance.
- Step 2: Choose the correct thrust bolt assembly (right-hand or left-hand threaded) based on the direction required to retract the piston for your specific caliper.
- Step 3: Slide one of the retainer plates onto the threaded shaft of the selected thrust bolt assembly.
- Step 4: Attach the chosen adapter to the end of the thrust bolt assembly. The embedded magnets will help secure the adapter in place.

Operating Instructions
Once the tool is assembled with the correct adapter and thrust bolt, proceed with the following steps to retract the brake caliper piston:
- Step 1: Position the assembled tool against the brake caliper piston. Ensure the adapter is flush against the piston face and the retainer plate is against the caliper body.
- Step 2: Use the T-handle to slowly rotate the thrust bolt. For calipers that require the piston to be rotated back (common on rear disc brakes with integrated parking brakes), turn the T-handle in the appropriate direction (clockwise or counter-clockwise) to retract the piston. For calipers that simply need to be pushed back, the tool will compress the piston.
- Step 3: Continue turning until the piston is fully retracted, creating enough space for the new, thicker brake pads. Do not over-retract the piston beyond its necessary travel.
- Step 4: Carefully remove the tool from the caliper. Install the new brake pads and reassemble the brake caliper and wheel according to your vehicle's service manual.

Adapter Compatibility
The kit includes 18 adapters designed for broad vehicle compatibility. Below is a general guide for some common applications:



Magnetic Adapter Feature
The thrust bolt assemblies feature embedded magnets to securely hold the selected adapter in place during use, preventing slippage and improving ease of operation.

Bidirectional T-Handle
The tool includes both right-hand and left-hand threaded thrust bolt assemblies, allowing for piston retraction in either clockwise or counter-clockwise directions, accommodating various caliper designs.

Maintenance
Proper maintenance ensures the longevity and reliable performance of your brake caliper compression tool set:
- Cleaning: After each use, wipe down all components with a clean cloth to remove brake dust, grease, and other contaminants. A mild degreaser can be used if necessary, followed by thorough drying.
- Lubrication: Periodically apply a light coat of machine oil or grease to the threaded shafts of the thrust bolt assemblies to ensure smooth operation and prevent rust.
- Inspection: Regularly inspect all adapters, plates, and thrust bolts for signs of wear, damage, or corrosion. Replace any damaged components immediately to maintain safety and effectiveness.
- Storage: Always store the tool set in its original storage case in a dry, clean environment. This protects the tools from moisture, dust, and physical damage.

Troubleshooting
If you encounter issues while using the brake caliper compression tool set, consider the following:
- Adapter Does Not Fit: Double-check the vehicle's make and model against the adapter compatibility chart. Ensure the correct adapter is selected for the specific piston design (e.g., single-pin, double-pin, or multi-pin).
- Piston Difficult to Retract: Ensure the correct thrust bolt assembly (right-hand or left-hand threaded) is being used for the caliper. Some pistons require rotation while being compressed. If excessive force is needed, inspect the caliper for damage or seized components. Never force the tool, as this can damage the caliper or the tool itself.
- Tool Slipping: Verify that the adapter is properly seated on the piston face and the retainer plate is stable against the caliper body. The magnetic feature should help secure the adapter. Ensure the T-handle is turned smoothly and steadily.
- Damaged Components: If any part of the tool set appears damaged or bent, discontinue use and replace the affected component. Using damaged tools can lead to injury or further damage to vehicle parts.
