Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, socket set, and a C-clamp or brake caliper tool.

2. Remove Wheel

Loosen the lug nuts slightly while the car is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the pads; replace if below the manufacturer's minimum specification.
Remove Old Pads: Use a socket to remove caliper bolts and carefully slide the caliper off the rotor.
Install New Pads: Slide new pads into the caliper bracket. Ensure that the pads are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Rotors: If the rotors are damaged, remove any retaining screws and slide the rotor off the hub.
Install New Rotors: Place the new rotor onto the hub, securing it with screws if applicable.

5. Reassemble Brake Components

Reattach the caliper over the new pads and rotor. Tighten caliper bolts to the manufacturer’s specified torque values (refer to service manual).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Lower the vehicle to the ground and fully tighten the lug nuts in a crisscross pattern to the specified torque.
Pump the brake pedal a few times to ensure proper seating of the pads and caliper.
