- Corrosion or rust buildup
- Brake fluid contamination
When the piston becomes stuck or seized, it can cause a range of problems, including:
- Reduced braking performance
- Increased stopping distance
- Difficulty engaging or disengaging the parking brake
- Brake fluid leakage
Tools and Materials Needed
To retract the caliper piston with an integrated parking brake, you will need the following tools and materials:
- Caliper piston retraction tool
- Brake fluid
- Brake cleaner
- Rust inhibitor
- Gloves and safety glasses
Step-by-Step Instructions
Retracting the caliper piston with an integrated parking brake is a relatively straightforward process. Here are the step-by-step instructions:
Step 1: Jack Up the Vehicle
Before you start the process, make sure the vehicle is securely jacked up and supported by jack stands. This will give you clearance to work underneath the vehicle.
Step 2: Remove the Wheel (See Also: Brake Fading Is Caused When)
Remove the wheel to gain access to the brake caliper. You can use a lug wrench to loosen the lug nuts, then raise the wheel off the ground.
Step 3: Remove the Caliper
Use a caliper removal tool to loosen the caliper bolts. Then, slide the caliper off the rotor and set it aside.
Step 4: Remove the Brake Pads
Remove the brake pads from the caliper. You may need to use a screwdriver or pliers to release the retaining clips.
Step 5: Inspect the Piston
Inspect the piston for any signs of corrosion or rust buildup. Use a rust inhibitor to clean and protect the piston.
Step 6: Apply Brake Fluid
Apply a small amount of brake fluid to the piston to help it move smoothly.
Step 7: Retract the Piston
Use the caliper piston retraction tool to retract the piston. Apply gentle pressure and slowly move the piston back into the caliper. (See Also: What Happens With Low Brake Fluid)
Step 8: Reinstall the Brake Pads
Reinstall the brake pads, making sure they are properly seated and retained by the retaining clips.
Step 9: Reinstall the Caliper
Reinstall the caliper, making sure it is securely fastened to the rotor.
Step 10: Bleed the Brake System
Bleed the brake system to remove any air that may have entered the system during the process.
Conclusion
Retracting the caliper piston with an integrated parking brake is a relatively straightforward process that requires the right tools and materials. By following the step-by-step instructions outlined above, you should be able to successfully retract the piston and restore your vehicle’s braking performance.

Here are five FAQs related to ‘How To Retract Caliper Piston With Integrated Parking Brake’:
Frequently Asked Questions
Q: What is the correct procedure to retract the caliper piston with an integrated parking brake?
The correct procedure to retract the caliper piston with an integrated parking brake is to first release the parking brake. Then, use a piston compressor or a C-clamp to slowly retract the piston while monitoring the brake fluid level. Make sure not to over-retract the piston, as this can cause damage to the brake system.
Q: Why is it important to monitor the brake fluid level when retracting the caliper piston?
It is important to monitor the brake fluid level when retracting the caliper piston to ensure that the piston does not retract too far and cause the brake fluid level to drop too low. This can cause air to enter the brake system, leading to spongy brake pedal feel and reduced braking performance.
Q: Can I use a regular caliper piston compressor to retract the caliper piston with an integrated parking brake?
No, it is not recommended to use a regular caliper piston compressor to retract the caliper piston with an integrated parking brake. The integrated parking brake requires a specialized piston compressor that is designed specifically for this type of brake system. Using a regular caliper piston compressor can cause damage to the brake system.
Q: What happens if I over-retract the caliper piston with an integrated parking brake?
If you over-retract the caliper piston with an integrated parking brake, it can cause damage to the brake system, including damage to the brake pads, rotors, and caliper. It can also cause the brake fluid level to drop too low, leading to air entering the brake system and causing spongy brake pedal feel and reduced braking performance.
Q: How do I know if I have successfully retracted the caliper piston with an integrated parking brake?
You know you have successfully retracted the caliper piston with an integrated parking brake when the piston is fully retracted and the brake fluid level is at the recommended level. You should also check the brake system for any signs of air leaks or other damage before using the brakes.
