Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Brake Pads

Check the thickness of the brake pads; if less than 3mm, replace them.
Remove the caliper bolts with a socket wrench.
Slide the caliper off the rotor and hang it securely using a bungee cord.

B. Check and Replace Brake Rotors

Measure rotor thickness with a micrometer; if below specifications, replace.
Remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install new rotor ensuring it is seated properly.

C. Install New Brake Pads

Apply brake grease to the backing of the new pads to prevent noise.
Insert the new pads into the caliper bracket.
Reinstall the caliper over the new pads and torque bolts to manufacturer specifications (usually around 25-35 ft-lbs).

4. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the specified value (usually 80-100 ft-lbs).
Lower the vehicle from the jack stands.
Reconnect the negative battery terminal.
