Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, socket set, and safety goggles.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery (negative terminal) to ensure safety while working on the electrical components if necessary.

2. Lift the Vehicle

Using the jack, lift the vehicle and secure it with jack stands.
Remove the wheels using a lug wrench to access the brake components.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads. If they are worn down to 3mm or less, they need replacement.
Replacement:
1. Remove the caliper bolts using the appropriate socket.
2. Slide the caliper off the brake pads and hang it securely to avoid straining the brake line.
3. Remove the old brake pads from the bracket.
4. Apply brake grease to the back of the new pads to reduce noise.
5. Install the new brake pads into the caliper bracket.
6. Reattach the caliper and tighten the bolts to the manufacturer's specified torque (usually around 25-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check for warping or deep grooves.
Replacement:
1. If rotors need replacement, remove the caliper bracket and then the rotor.
2. Install new rotors onto the hub, ensuring they are seated properly.
3. Reattach the caliper and bracket, tightening to the specified torque.

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to the specified torque (usually around 80-100 ft-lbs).

6. Final Checks

Reconnect the battery.
Test the brake pedal for firmness before starting the vehicle and check for any abnormal noises when pressing the brake.
