Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to ensure safety.

2. Remove Wheel

Tools Required: Socket set, jack, and jack stands
Sub-steps:
1. Loosen the lug nuts of the wheel before lifting the vehicle.
2. Use a jack to lift the vehicle and place it securely on jack stands.
3. Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, brake cleaner, and C-clamp or brake caliper tool
Sub-steps:
1. Remove the caliper bolts and carefully lift the caliper off the rotor.
2. Inspect the brake pads. If the thickness is less than 3mm, they should be replaced.
3. Use a C-clamp to compress the caliper piston back into the caliper housing.
4. Remove the old brake pads and clean the caliper bracket with brake cleaner.
5. Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Hammer, rotor puller (if necessary)
Sub-steps:
1. Inspect the rotors for scoring or warping. Replace if necessary.
2. If replacing, remove the old rotor by unscrewing any retaining screws and gently tapping it off with a hammer.
3. Install the new rotor, ensuring it is seated properly.

5. Reassemble Brake Components

Tools Required: Torque wrench
Sub-steps:
1. Reattach the caliper over the new brake pads and secure it with the caliper bolts.
2. Torque the caliper bolts to the manufacturer’s specifications.
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Tools Required: None
Sub-steps:
1. Lower the vehicle from the jack stands and remove the jack.
2. Tighten the lug nuts in a star pattern to the manufacturer's torque specifications.
3. Reconnect the battery.
