Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Brake Pads

Remove the wheel using a lug wrench.
Remove the brake caliper by loosening the caliper bolts (usually a socket or wrench is required).
Take out the brake pads from the caliper bracket.
Inspect the pads for wear; replace if less than 3mm thick.
Insert new brake pads into the caliper bracket.

3. Inspect and Replace Brake Rotors

If rotors are warped or damaged, remove the rotor from the hub after caliper removal.
Clean the hub surface with a wire brush to ensure proper mounting.
Install new rotors, ensuring they are seated flush against the hub.

4. Reassemble Braking System

Reinstall the brake caliper over the new pads and rotor.
Tighten caliper bolts to the specified torque value (usually around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
Pump the brake pedal to ensure proper brake engagement before driving.
