Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the front or rear of the CR-V (depending on where the noise is coming from).
Secure with jack stands for safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the wheel bolts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads. If they are less than 3mm, replace them.
Remove: Unbolt the brake caliper using a socket set. Hang the caliper using a hook to avoid stressing the brake line.
Replace: Remove the old brake pads and install new pads, ensuring they are properly aligned.

5. Inspect and Resurface/Replace Rotors

Inspect: Check the rotors for any grooves, cracks, or discoloration.
If needed: Use a brake lathe to resurface the rotors or replace them entirely. Ensure proper torque specifications are followed when installing new rotors.

6. Reassemble Components

Reattach the caliper over the new pads and ensure all bolts are tightened to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

7. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the proper torque specification.
