Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Wheel chocks
- Lug wrench
- Torque wrench
- Brake cleaner
- Soft brush for cleaning
Ensure the vehicle is in a safe position, parked on a level surface, and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during repair.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper by unscrewing the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it using a hook or bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Inspect the brake pads for wear; if the friction material is less than 3mm thick, replace the pads.
- Install new brake pads, ensuring they are oriented correctly and seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Use a micrometer to measure the rotor thickness; if the thickness is below specifications or if there are visible grooves, replace the rotors.
To replace, remove the rotor retaining screws (if equipped) and slide the rotor off the hub.
Install new rotors, aligning them properly, and secure with screws if applicable.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor.
Torque the caliper mounting bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands.
Tighten the lug nuts to the manufacturer's torque specifications (usually 70-90 ft-lbs).
Reconnect the battery and start the vehicle; pump the brake pedal a few times to ensure proper pad seating.
