Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Safety gear: gloves and safety goggles.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Jack up the vehicle and secure it with jack stands.
Remove the wheel to gain access to the brake components.

3. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads. If they are below the minimum thickness (usually around 3mm), they need replacing.
Remove Caliper: Use a socket set to remove the caliper mounting bolts. Carefully slide the caliper off the rotor and support it with a bungee cord or similar device to avoid stress on the brake line.
Replace Pads: Remove old pads from the caliper bracket. Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if needed)

Check Rotors: Measure rotor thickness with a micrometer. If below specifications or if they are scored, they need replacement.
Remove Rotors: Remove the caliper bracket (if applicable) and then slide off the rotor.
Install New Rotor: Clean the hub surface, install the new rotor, and secure it as per manufacturer specifications.

5. Reassemble and Bleed Brakes

Reinstall Caliper: Position the caliper over the new pads and secure it using the caliper mounting bolts. Torque bolts to manufacturer specifications.
Bleed Brakes: If the brake fluid was drained, bleed the brake system using a brake bleeder kit to remove air from the lines.

6. Reinstall Wheel and Lower Vehicle

Reattach the wheel, tightening the lug nuts in a star pattern to ensure even torque.
Lower the vehicle from the jack stands and remove the jack.
