Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Engage the parking brake and place wheel chocks behind the rear wheels.
Gather necessary tools and parts for the repair.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts with a socket set while the wheel is still on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.
Tools Required: Socket set, jack, jack stands

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the brake pads and support it with a bungee cord or hook (do not let it dangle).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any signs of damage or wear.
5. Install new brake pads into the caliper bracket (ensure they are oriented correctly).
Tools Required: Socket set

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Inspect the brake rotor for grooves, scoring, or excessive wear.
2. If replacement is needed, remove the rotor by unscrewing the retaining screws (if applicable).
3. Install the new rotor, ensuring it is seated properly against the hub.
Tools Required: Socket set, possibly a rotor puller for stubborn rotors

5. Reassemble and Test

Sub-steps:
1. Reattach the caliper over the new brake pads.
2. Tighten the caliper bolts to the manufacturer’s specifications (typically 20-25 lb-ft).
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and torque the lug nuts to the specified value (usually 100-150 lb-ft).
Tools Required: Torque wrench
