Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, safety goggles, gloves.
Raise the vehicle using the jack and secure it with jack stands.
Remove the wheel using the lug wrench.

2. Remove Brake Pads

Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor without stressing the brake line.
Remove the old brake pads from the caliper bracket.

3. Inspect and Replace Components

Brake Pads:
- Check the thickness; if less than 3mm, replace with new pads.
- Apply brake grease to the back of new pads.
Brake Rotors:
- Inspect for scoring or warping; if damaged, replace with new rotors.
- Clean the rotor surface with brake cleaner and a cloth.

4. Reassemble Brake Components

Slide the new brake pads into the caliper bracket.
Position the caliper over the new pads and rotor.
Tighten the caliper bolts to manufacturer specifications using a torque wrench.

5. Reinstall Wheel and Lower Vehicle

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to the specified torque.

6. Test Brakes

Pump the brake pedal a few times to seat the pads.
Conduct a test drive to ensure proper function and listen for any further noises.
