Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electronic components.

2. Inspect and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, rotors, and brake pads.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using the lug wrench.
Inspect the brake rotors for warping (look for any uneven surfaces). If warped, proceed to replace:
- Remove the caliper bolts and detach the caliper.
- Slide the caliper off the rotor and support it (do not let it hang by the brake line).
- Remove the rotor (if necessary, use a rubber mallet to tap it off).
- Install the new rotor and ensure it is seated properly.
- Reinstall the caliper and secure the bolts to manufacturer specifications (typically 20-30 Nm).

3. Replace Brake Pads

Remove old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to contact points.
Install new brake pads and ensure they are seated correctly.
Reinstall the wheel and torque the lug nuts to manufacturer specifications (usually 100-120 Nm).

4. Check Suspension Components

Inspect control arms, bushings, and tie rods for signs of wear or damage.
Replace any damaged or worn components following manufacturer specifications for torque.

5. Wheel Alignment and Balancing

After all repairs, take the vehicle to a professional for a wheel alignment and balance to ensure proper handling and tire wear.
