Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is applied.
Disconnect the battery to ensure safety during the repair.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts and carefully slide the caliper off the brake rotor.
2. Support the caliper with a bungee cord or similar device to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Check the caliper slides and lubricate if necessary.
5. Install new brake pads, ensuring they are properly seated.
Tools Required: Socket set, torque wrench, brake cleaner, bungee cord.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Remove the caliper bracket if replacing rotors.
2. Remove the rotor by sliding it off the hub (may require hammering if rusted).
3. Clean the hub surface where the new rotor will sit.
4. Install the new rotor, ensuring it is properly aligned.
Tools Required: Hammer (if needed), brake cleaner.

5. Reassemble Components

Sub-steps:
1. Reattach the caliper bracket and torque the bolts to the manufacturer’s specification.
2. Reinstall the caliper over the new pads and torque the caliper bolts.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and fully tighten the lug nuts in a star pattern.
Torque Values: Refer to the manufacturer's specifications for specific torque values.

6. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Pump the brake pedal to ensure proper engagement of the brake pads.
3. Check brake fluid level and top off if necessary.
