Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent vehicle movement.
Disconnect the battery for safety.

2. Remove Wheel

Loosen the lug nuts with a socket wrench while the vehicle is still on the ground.
Use a jack to lift the vehicle and place jack stands for safety.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and hang it using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Compare new brake pads to the old ones for proper fit.
Apply brake grease to the backs of the new pads and install them into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor for thickness and any scoring.
If replacement is needed, remove the rotor by unscrewing the retaining screws or bolts.
Install the new rotor, ensuring it is seated properly.

5. Reassemble and Test

Reattach the caliper over the new pads and secure it with the caliper bolts, tightening to the manufacturer’s specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications using a torque wrench.
Reconnect the battery.
