Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and micrometer.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported by jack stands before beginning work.

2. Remove Wheel

Loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Check the brake pads for wear; if they are below the minimum thickness, replace them.
Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the rotor without damaging the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for scoring or warping; if damaged, replace them.
Remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Clean the hub surface with brake cleaner.
Install new rotors by reversing the removal process and securing with retaining screws.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads.
Tighten the caliper bolts to the manufacturer's torque specifications (typically around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer's specification (typically around 100-110 Nm).
Pump the brake pedal a few times to ensure proper brake pad seating.
