Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, socket set, torque wrench, and safety glasses.
Safety Warning: Always ensure the vehicle is on a flat surface and engage the parking brake before raising the vehicle.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully lift the caliper off the rotor without disconnecting brake lines.
- Inspect the brake pads for thickness; replace if worn down to less than 3mm.
Brake Rotors:
- Check the surface of the rotors for grooves or scoring. If damaged, consider resurfacing or replacing.
Brake Calipers:
- Inspect for any signs of sticking or uneven wear.

4. Replace Brake Pads and/or Rotors

If pads are worn, remove the old pads and install new ones:
- Apply brake grease to the back of the new pads to prevent squeaking.
- Ensure the clips are properly seated.
If rotors need replacement:
- Remove the rotor by unscrewing any retaining screws (if applicable).
- Install the new rotor and secure it according to manufacturer specifications.

5. Reassemble Components

Reinstall the caliper over the new pads.
Tighten the caliper bolts to the manufacturer's torque specification.
Reattach the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle and remove the jack stands.
Tighten the lug nuts in a crisscross pattern to ensure even pressure.
