Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and wear safety gear.
Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, caliper tool.

2. Remove Wheel

Loosen lug nuts slightly with a lug wrench.
Lift the vehicle using a jack and securely place it on jack stands.
Remove the wheel to access brake components.

3. Inspect and Replace Brake Pads

Inspect Calipers: Check for proper movement and ensure the caliper slides smoothly.
Remove Brake Pads: Unbolt the caliper using a socket set and carefully slide it off the rotor. Remove the old brake pads.
Install New Pads: Clean the caliper bracket and apply brake grease to the back of the new pads. Install new pads into the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Check Rotor Condition: If rotors show signs of wear or warping, remove them by unbolting from the hub.
Replace Rotors: Install new rotors and ensure they are properly seated. Torque bolts to manufacturer specifications.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Torque caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Remove jack stands and lower the vehicle.
Tighten lug nuts to the specified torque value.
Test the brakes by pumping the pedal several times before driving.
