Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to prevent the vehicle from rolling.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
Wire brush
Safety glasses and gloves

2. Remove Wheel

Loosen the lug nuts slightly while the wheel is still on the ground.
Jack up the vehicle 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 the socket set.
Carefully slide the caliper off the rotor while supporting it to avoid strain on the brake line.
Inspect the brake pads for wear; replace them if they are worn down to the indicator.
- If replacing, remove the old pads and install new pads ensuring they are properly seated.
Apply brake grease to the backing of the new pads to prevent squeaking.

4. Inspect and Resurface or Replace Brake Rotors

Check the rotor surface for scoring or damage.
If the rotor is within specifications, clean it with brake cleaner and a wire brush.
If the rotor is warped or damaged, remove it and replace it with a new one.
- Follow the manufacturer's specifications for rotor thickness.

5. Reassemble Components

Reinstall the brake caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to specified values.
