Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety during brake work.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands.
Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the wheel completely.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, brake cleaner.
Sub-steps:
1. Remove caliper bolts using a socket wrench and carefully slide the caliper off the rotor.
2. Support the caliper with a bungee cord or rope to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the pads for wear; if less than 3mm thick, replace them with new ones.
5. Apply brake cleaner to clean the caliper bracket and rotor.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Torque wrench.
Sub-steps:
1. Check rotors for wear; if they are below the minimum thickness or have deep grooves, replace them.
2. If replacing, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
3. Install new rotors, ensuring they are seated correctly.
4. Torque the rotor screws to manufacturer specifications.

5. Reassemble Braking Components

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the caliper over the new brake pads.
2. Tighten caliper bolts to the manufacturer's torque specs.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and fully tighten the lug nuts in a star pattern.

6. Final Inspection

Tools Required: Brake fluid (if needed).
Sub-steps:
1. Check brake fluid level and top off if necessary.
2. Reconnect the battery.
3. Start the vehicle and pump the brakes a few times to ensure proper engagement.
