Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety gear including gloves and goggles.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts.
Carefully slide the caliper off the brake rotor.
Remove the old brake pads from the caliper bracket.
Compare new pads with old ones for size and wear.
Install new brake pads, ensuring they are positioned correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotor condition; if warped or damaged, proceed to replace.
Remove the caliper bracket if necessary to access the rotor.
Unscrew the retaining screws (if present) and slide the rotor off the hub.
Install the new rotor, ensuring it is seated properly.

5. Reassemble and Test

Reattach the caliper over the new pads and rotor, tightening bolts to manufacturer specifications (typically around 25-35 Nm).
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specification (usually around 100-120 Nm).
Pump the brake pedal a few times to ensure proper seating of the pads against the rotor.
