Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and securely lift with jack stands.
Safety: Wear gloves and safety goggles.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the wheel is still on the ground.
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: Examine the brake pads for thickness; replace if they are worn below the manufacturer's specifications (usually 3mm or less).
Remove old pads: Unclip or unbolt the caliper and gently slide it off the rotor.
Install new pads: Apply brake grease to the back of the new pads to prevent squealing. Position the new pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect: Check rotors for any signs of damage or excessive wear.
Remove rotors: If replacing, remove the caliper bracket bolts and slide the rotor off the hub.
Install new rotor: Place the new rotor on the hub, ensuring it is seated correctly.

5. Reassemble Braking System

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specifications (usually around 30-40 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer’s specifications (usually in a crisscross pattern).
Pump the brake pedal a few times to ensure proper pad seating against the rotor.
