Solution

1. Preparation

Gather all necessary tools and parts. Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Screwdriver set
- Brake cleaner
- C-clamp or brake caliper tool
Safety Warnings:
- Always wear safety gloves and goggles.
- Allow the vehicle to cool down before working on the brakes.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and support it securely with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set and carefully slide the caliper off the rotor.
Secure the caliper with a bungee cord or rope to prevent stress on the brake line.
Remove the old brake pads from the caliper bracket and inspect for wear.
If pads are worn down (less than 3mm thick), replace them with new ones.
Apply brake grease to the back of the new pads to reduce squeaking.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or warping; if damaged, replace the rotor.
To remove the rotor, unscrew the retaining screws (if applicable) and slide it off the hub.
Install the new rotor, ensuring it is seated correctly.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor, ensuring it moves freely.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel, hand-tightening the lug nuts before lowering the vehicle.

6. Final Checks

Lower the vehicle and tighten the lug nuts to the manufacturer’s torque specifications in a star pattern.
Pump the brake pedal to ensure the pads seat correctly against the rotor.
