Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts slightly while the car is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect: Check the brake pad thickness and look for uneven wear.
Replace: If uneven wear is found, remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Remove the old brake pads and clean the caliper bracket with brake cleaner.
- Install new brake pads ensuring they are seated properly.

4. Check and Replace Brake Rotors (if necessary)

Inspect: Measure rotor thickness and runout. If out of spec, replace them.
Remove the rotor by unscrewing the rotor retaining screws (if present).
Install the new rotor and secure it in place.

5. Reinstall Caliper and Wheel

Reattach the caliper, ensuring all bolts are torqued to manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and finish torquing the lug nuts to the proper specifications.

6. Final Check

Pump the brake pedal to ensure proper pad seating before driving.
Conduct a test drive to check for any unusual noises or performance issues.
