Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness; replace if worn below 3mm.
Remove Old Brake Pads: Unbolt the caliper using a socket set and slide it off the rotor. Remove the old brake pads from the caliper bracket.
Install New Brake Pads: Apply brake grease to the backing of the new pads. Place the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotor Condition: If rotors are scored or warped, they need replacement.
Remove Rotors: Unbolt the rotor from the hub and slide it off.
Install New Rotors: Place the new rotor onto the hub and secure it with bolts.

5. Reassemble Braking System

Reattach Caliper: Slide the caliper back over the new pads and torque the caliper bolts to the manufacturer's specifications (usually around 20-25 ft-lbs).
Reinstall Wheel: Place the wheel back onto the hub and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).
Pump the brake pedal a few times to ensure proper brake function before test driving.
