Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Remove Wheels

Use a lug wrench to loosen the lug nuts.
Raise the vehicle using a jack and secure with jack stands.
Remove the wheels to gain access to the brake components.

3. Check Brake Rotors

Inspect rotors for signs of warping or uneven wear.
If warped, proceed to remove the rotors using a socket set.
If the rotors are within specifications, clean them with brake cleaner.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket.
Carefully lift the caliper and support it with a bungee cord (do not let it hang on the brake line).
Remove old brake pads and install new ones, ensuring proper orientation.
Compress the caliper piston using a brake caliper tool and reattach the caliper.

5. Reinstall Rotors and Wheels

If rotors were replaced, install new rotors and torque to manufacturer specifications (typically around 80-100 ft-lbs).
Reinstall wheels and hand-tighten lug nuts.
Lower the vehicle and use the torque wrench to tighten lug nuts in a crisscross pattern.

6. Final Checks

Reconnect the battery.
Test brake function before driving by pressing the brake pedal to ensure proper engagement.
