Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Brake Pads

Remove the Wheel
- Use a lug wrench to loosen the lug nuts; elevate the vehicle using a jack and secure it with jack stands.
- Completely remove the lug nuts and take off the wheel.
Remove Caliper
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor, supporting it with a bungee cord to avoid stressing the brake line.
Inspect Brake Pads
- Check the thickness of the pads. Replace if below 1/8 inch.
- Look for uneven wear or cracking.
Replace Brake Pads
- Remove the old pads and install new ones, ensuring proper orientation.
- Apply brake grease to the backing of the pads to prevent noise.
Reinstall Caliper
- Slide the caliper back over the new pads and tighten the mounting bolts to manufacturer specifications (typically 20-25 ft-lbs).
Reattach Wheel
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the specified value (usually around 80-100 ft-lbs).

3. Inspect and Replace Brake Rotors (if needed)

Remove the Caliper and Pads
- Follow steps 2 and 3 from the above section to remove the caliper and pads.
Remove the Rotor
- If rotors are secured with screws, remove them with a screwdriver.
- Slide the rotor off the hub; if it’s stuck, gently tap it with a rubber mallet.
Inspect Rotors
- Check for grooves, warping, or excessive rust.
- Measure thickness with a micrometer; replace if below minimum spec.
Install New Rotor
- Position the new rotor on the hub.
- Reinstall any securing screws, if applicable.
Reinstall Caliper and Pads
- Follow steps 4 and 5 from the above section to reinstall brake pads and calipers.
