Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Use wheel chocks to prevent the vehicle from rolling.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench.
Take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor.
- Check the brake pads for wear; replace if they are worn down to the indicator.
Replace Brake Pads:
- Remove the old pads and install new ones, ensuring they fit snugly.
- Apply brake grease to the backing of the pads to reduce noise.

4. Inspect and Replace Brake Rotors (if needed)

Inspect Rotors:
- Check for grooves, scoring, or warping.
- If damaged, proceed to replace.
Replace Rotors:
- Remove the caliper bracket if necessary.
- Take off the rotor by unscrewing the retaining screws.
- Install new rotors, ensuring they are clean and free of grease.

5. Reassemble Brake Components

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and tighten lug nuts in a star pattern to ensure even pressure.

6. Final Checks

Pump the brake pedal a few times to seat the pads against the rotor.
Check brake fluid level and top off if necessary.
Lower the vehicle from the jack stands.
