Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves for personal protection.

2. Remove Wheel

Loosen lug nuts with a lug wrench while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect the brake pads for wear; if the material is less than 3mm, replace them.
If replacing, remove the caliper bolts with a socket set.
Slide the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
Remove the old brake pads and install new ones, ensuring they are oriented correctly.
Apply brake grease to the back of the new pads to prevent noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for grooves or warping using a caliper.
If new rotors are needed, remove the caliper bracket bolts and take off the caliper bracket.
Remove the rotor from the hub. If it is stuck, tap it gently with a rubber mallet.
Install new rotors, ensuring they are clean and properly seated.

5. Reassemble

Reattach the caliper bracket and torque bolts to the manufacturer’s specifications.
Slide the caliper back over the new pads and torque the caliper bolts.
Reinstall the wheel and torque the lug nuts in a star pattern to the recommended specifications.
Lower the vehicle and double-check all connections.
