Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads
- Remove the caliper bolts using a socket set.
- Slide the caliper off and check the pads for thickness; replace if less than 3mm.
Replace Brake Pads
- Remove old pads by sliding them out of the caliper bracket.
- Install new brake pads, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors
- Check for warping or scoring on the rotor surface.
Replace Rotors
- If worn, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
- Install new rotors, ensuring they are clean and free from oil or grease.

5. Reassemble Components

Reattach the brake caliper over the new pads and secure with bolts to manufacturer’s torque specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts to the specified torque (typically 80-100 ft-lbs).

6. Final Check

Reconnect the battery.
Pump the brake pedal to ensure proper pad seating.
