Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues.

2. Wheel Removal

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack 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. Brake Pad and Rotor Inspection

Sub-steps:
1. Inspect brake pads for thickness; replace if less than 3mm.
2. Check brake rotors for signs of wear, scoring, or heat damage.
3. Measure rotor thickness; replace if below manufacturer specifications.
Tools Required: Caliper gauge, flashlight.

4. Replace Brake Components (if necessary)

Sub-steps:
1. If pads are worn, remove the caliper by unscrewing the mounting bolts.
2. Remove old brake pads and install new ones, ensuring proper orientation.
3. If rotors are damaged, remove the old rotor and install the new rotor.
4. Reattach the caliper over the new pads and torque to manufacturer specifications.
Tools Required: Socket set, torque wrench, brake cleaner.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle off the jack stands and tighten lug nuts to the proper torque.
3. Reconnect the battery.
4. Test the brakes by pressing the pedal a few times to ensure proper operation.
Tools Required: Torque wrench, lug wrench.
