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

Loosen the lug nuts on the wheel using a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect the brake pads for wear; if the friction material is below 3mm, replacement is necessary.
Remove the caliper bolts using a socket wrench and carefully detach the caliper from the rotor.
Slide the old brake pads out of their slots.
Install new brake pads, ensuring they are seated properly in the caliper bracket.

4. Check and Resurface/Replace Rotors

Inspect the brake rotors for damage or excessive wear; if they are scored or warped, they may need resurfacing or replacement.
If replacing, remove the rotor by unscrewing the retaining screws.
Install new or resurfaced rotors by aligning them with the hub and securing with screws.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads and secure it with caliper bolts. Torque to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified torque value.

6. Final Checks

Pump the brake pedal several times to ensure proper contact between the pads and rotors.
Check the brake fluid level again and top off if necessary.
