- Consult the vehicle’s repair manual or a professional mechanic if you are unsure about any part of the process.
Necessary Tools and Equipment
To remove the rear brake caliper, you will need the following tools and equipment:
- C-Clamps or caliper piston compressor
- Brake caliper wrench or socket
- Torque wrench
- Brake pad spacers or shims
- Wheel chocks (optional)
- Jack and jack stands
- Socket set or ratchet and extension
- Brake cleaner and lubricant
Step 1: Loosen the Brake Caliper Bolts
Before removing the brake caliper, you need to loosen the caliper bolts. These bolts hold the caliper in place and must be loosened before attempting to remove the caliper. To loosen the bolts: (See Also: What Dies Brake Fluid Do)
- Use a brake caliper wrench or socket to loosen the caliper bolts in a star pattern (tightening one bolt a little, then moving to the next one, and so on).
- Apply gentle pressure to avoid damaging the brake caliper or brake rotor.
- Loosen the bolts until they are loose, but do not remove them yet.
Step 2: Remove the Brake Caliper Bolts
Once the caliper bolts are loosened, you can remove them completely. To remove the bolts:
- Use a socket or ratchet and extension to remove the caliper bolts.
- Place the bolts in a safe location to avoid losing them.
- Be careful not to damage the brake caliper or brake rotor during the removal process.
Step 3: Remove the Brake Caliper
With the caliper bolts removed, you can now remove the brake caliper. To remove the caliper:
- Gently pull the brake caliper away from the brake rotor.
- Use a gentle rocking motion to dislodge the caliper from the rotor.
- Be careful not to damage the brake caliper or brake rotor during the removal process.
Step 4: Remove the Brake Pads
Once the brake caliper is removed, you can remove the brake pads. To remove the brake pads:
- Use a screwdriver or punch to release the brake pad retaining clips.
- Gently pull the brake pads out of the caliper.
- Be careful not to damage the brake pads or caliper during the removal process.
Step 5: Inspect and Clean the Brake Rotor
With the brake caliper and brake pads removed, you can inspect and clean the brake rotor. To inspect and clean the brake rotor:
- Visually inspect the brake rotor for excessive wear, scoring, or damage.
- Use a brake cleaner to remove any dirt, grime, or debris from the rotor.
- Use a wire brush to remove any corrosion or rust from the rotor.
Step 6: Reinstall the Brake Caliper
Once the brake rotor is clean and inspected, you can reinstall the brake caliper. To reinstall the brake caliper:
- Place the brake caliper over the brake rotor, ensuring it is properly aligned.
- Use the caliper bolts to secure the caliper in place.
- Tighten the caliper bolts in a star pattern to ensure even pressure.
Step 7: Reinstall the Brake Pads
With the brake caliper reinstalled, you can reinstall the brake pads. To reinstall the brake pads: (See Also: Should You Set Your Parking Brake When Parking)
- Place the brake pads into the caliper, ensuring they are properly seated.
- Use the brake pad retaining clips to secure the pads in place.
- Make sure the pads are properly aligned and seated.
Step 8: Bleed the Brake System
Once the brake caliper and brake pads are reinstalled, you need to bleed the brake system to remove any air that may have entered the system. To bleed the brake system:
- Use a brake bleeding kit to remove air from the system.
- Follow the manufacturer’s instructions for bleeding the brake system.
- Test the brake system to ensure it is functioning properly.

Frequently Asked Questions: How to Remove Rear Brake Caliper
What tools do I need to remove the rear brake caliper?
To remove the rear brake caliper, you’ll need a few specialized tools, including a lug wrench or tire iron to loosen the wheel, a caliper piston compressor to retract the brake piston, and a wrench or socket to remove the caliper bolts. You may also need a brake cleaner and a rag to clean the area.
How do I retract the brake piston to remove the rear brake caliper?
To retract the brake piston, you’ll need to use a caliper piston compressor. This tool will allow you to slowly and safely push the piston back into the caliper, giving you clearance to remove the caliper from the rotor. Be sure to follow the manufacturer’s instructions for the compressor and take your time to avoid damaging the piston or caliper. (See Also: How To Turn On Parking Brake)
Do I need to bleed the brake system after removing the rear brake caliper?
Yes, it’s highly recommended to bleed the brake system after removing the rear brake caliper to remove any air that may have entered the system. This will ensure that your brakes are functioning properly and safely. You can use a brake bleeding kit to remove any air and fluid from the system.
Can I remove the rear brake caliper without removing the wheel?
In most cases, it’s not recommended to remove the rear brake caliper without removing the wheel. This is because the caliper is typically mounted to the rotor, which is attached to the wheel hub. Removing the wheel will give you better access to the caliper and make it easier to remove. However, some vehicles may have a design that allows for caliper removal without wheel removal, so be sure to consult your repair manual or a professional mechanic if you’re unsure.
How do I reinstall the rear brake caliper after replacing the brake pads?
When reinstalling the rear brake caliper, make sure to align it properly with the rotor and tighten the caliper bolts in a star pattern to avoid warping the rotor. Be sure to follow the manufacturer’s torque specifications for the caliper bolts and bleed the brake system to remove any air that may have entered during the process.
