Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.
Ensure the engine is off and has cooled down.

2. Remove Wheels

Using a jack, lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the front wheels.

3. Inspect and Replace Brake Components

A. Brake Rotors

Inspect: Look for signs of warping or excessive wear.
Replace if necessary:
- Remove the caliper by loosening the bolts with a socket set.
- Slide the caliper off the rotor and secure it with a bungee cord (do not let it hang by the brake line).
- Remove the rotor by unscrewing the retaining screws and pulling it off.
- Install the new rotor by reversing the removal steps.

B. Brake Pads

Inspect: Check for uneven wear.
Replace if necessary:
- Remove the caliper bracket if needed to access the pads.
- Replace old pads with new ones, ensuring the clips are properly seated.
- Reassemble the caliper and torque bolts to the manufacturer’s specifications (usually around 20-30 ft-lbs).

4. Check Suspension Components

Inspect control arms and bushings for any signs of damage or excessive wear.
Replace any worn components as necessary.

5. Wheel Alignment and Tire Balance

Take the vehicle to a professional for wheel alignment and tire balancing.
