Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove the Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is still on the ground.
2. Raise the vehicle with a jack and secure it on jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake grease.
Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor.
3. Inspect the brake pads for uneven wear; replace if thickness is below 3mm or if there are grooves.
4. Apply brake grease to the backing of the new pads to reduce noise.
5. Install the new brake pads in the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Tools Required: Brake cleaner, rotor gauge (if resurfacing).
Sub-steps:
1. Check the rotors for grooves or scoring. If needed, resurface the rotors or replace them if they are below the minimum thickness specification.
2. Clean the rotor surface with brake cleaner to remove any contaminants.
3. Reinstall the rotor, ensuring it is securely mounted.

5. Reassemble the Brake Components

Tools Required: Torque wrench.
Sub-steps:
1. Reattach the caliper over the new brake pads.
2. Tighten the caliper bolts to the manufacturer’s specified torque settings.
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Final Checks

Tools Required: Torque wrench.
Sub-steps:
1. Lower the vehicle off the jack stands using the jack.
2. Torque the lug nuts to the specified value.
3. Pump the brake pedal a few times to ensure proper brake engagement before driving.
