Solution

1. Preparation

Gather tools and materials needed.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the battery if working with electronic brake systems.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of damage or malfunction.
Install new brake pads, ensuring they are properly aligned and seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or excessive wear.
If replacement is needed, remove the caliper bracket bolts and slide off the rotor.
Install new rotors, ensuring they are clean and free of grease.
Reattach the caliper bracket and torque the bolts to the manufacturer's specification.

5. Reassemble and Test

Reinstall the caliper over the new pads and secure it with bolts.
Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery and perform a brake test at low speeds to ensure proper function.
